Beautiful Cars, Those Classic BMWs: An Interview with Diagonalt’s Pawel Bilas

Pawel hails from the land of the famous 80’s new wave band a-ha. We get the Norwegian’s “take on” his role as the owner and lead designer of Diagonalt, and its sister design firm Desagn. Our partnership with Diagonalt is a first for us and to celebrate, Pawel has given us his time in the interview below and a discount for our readers.

Enjoy!

RYE30 Racing: Your products are simple and modern. I feel like that style is a perfect fit for the subject matter because the classic BMWs you feature speak well for themselves. Can you talk about what might have inspired you to showcase the cars this way?

Well, I love the whole sensation of Bavarian cars. I can’t express myself what this nostalgic emotion does to my soul. I’m just simply, very into it. I think it’s the personalities, the mindset, the lifestyle…I’ve always been attracted to the simplicity and pure function. It kind of came out somehow. I wanted to give something from me to the enthusiasts – as a designer and enthusiast myself. It seems that everybody focuses on the most known models like M3 etc. I wanted to expose the cars that enthusiasts truly admire. The rarity, uniqueness and simple forms with personal touches. Back then, I didn’t know how to express it. One day I’ve noticed one drawing of the E30 – it was something. But I felt I can make it better, and here we are.

RYE30 Racing: It’s easy to make products at home these days by simply outsourcing, or designing and manufacturing them at home with design programs, high-quality printers, and 3D printing technology. How involved are you in the manufacturing of any of the products?

I do as much as I can! To give an example: I prefer to shoot the real cars in the right angles, that I can later work on. I often spend late evenings getting the lines the way I want. It’s all about showing the basics until the car looks complete. I’ve produced a lot of prints at home. I still do, but now just the custom prints. The rest is produced by a print house that I’ve collaborated for a while. It came to that point that I can not afford doing it at home. It took a while to find good materials and processes that I’m happy with. I also have one friend that helps me with the calendars shipment. To be honest, it’s cheaper to outsource bigger orders. In that way, I get more time to deal with promotions, customers, ideas and design of the new products. It’s my pleasure to do so.

RYE30 Racing: We noticed some fashionable displays of your One Model Prints on your Diagonalt homepage. What’s the best way to display your prints and calendars? Thank you! I’m trying to display my products in an honest and tasty kind of way. I think my minimalist side is talking there strong. I’m inspired by Dieter Ram, that once said that products we use every day affect our person and our well-being. He also meant that the product design should, therefore, be both neutral and restrained, to leave room for the user’s self-expression. Good design is thorough down to the last detail. Nothing must be arbitrary or left to chance. I would like it if people had that in mind, before displaying my products.

RYE30 Racing: RYE30 Racing has a mandate to practice the Four “R’s” (Reduce, Reuse, Recycle, Refuse) as much as possible in the course of our building and racing. Can you speak to any direct or indirect efforts to be sustainable or use recycled products?

Are we talking about car products? I love to search for used and rare BMW stuff! I like collecting, renovating and reusing old parts. I do also sell them sometimes when I realize that I don’t need them anymore.
This mindset translates to Diagonalt. Living nowadays and expressing nostalgic cars end its era couldn’t exist without a good sustainability story behind. All of my papers and materials are carefully selected to meet my imposed needs. Recycling suits my products very well. I think it’s the only way to do it.

RYE30 Racing: Do you have any products in development that you’re excited about offering?

Yes. I have plenty of car models that are not in the store yet. It takes quite a time preparing a good product presentation. You know, there is this thing, when you do things for yourself, you’re never happy and always find something that could be better. I’ve been planning to extend the horizon for stickers too. Everything is set, I just need to make some decisions about the model and color combination – it’s not that easy as it sounds.

About Pawel:

RYE30 Racing: I know very little about Norway. What is the car culture like there?

Different. However, I’m focused on the BMW culture and events. We have strong sociality. There is always something happening. Even during the winter. We tend to have fun with the cars on the frozen lakes. It’s the cheapest way of racing cars and brings lots of fun. I think racing cars are popular in Norway. There are many possibilities to do it safely and legally. The best thing is, that enthusiasts help each other a lot. Have you, for example, heard the story behind the renovation of DTM E30 M3 Jägermeister? It’s the perfect example of how shared passion unites and helps people. That’s why I love being into it. It’s not really about the cars – it’s the people and atmosphere that make it worth it.

RYE30 Racing: I browsed your portfolio, Desagn and was very impressed! How long have you been practicing as a professional graphic designer?

Professional – it’s when you first get paid for your work, isn’t it? Then I’ve been doing it for over ten years I think.

RYE30 Racing: What was your first job as a professional?

I can’t remember. Maybe I have too many thoughts about the future in my head. I’ve started sole proprietorship already during my high school and did different, weird projects for people and companies in my hometown.

RYE30 Racing: What would your ideal BMW be?

That would be a perfect condition Henna red BMW E30 M3. Probably with a few racing and personal relishes.

RYE30 Racing: Do you own any BMWs now?

I own only BMW’s. I do have a Zinobber red 2-Door E30 with M42 engine. I’ve always wanted to have a red IS, almost like from the first catalog page – Meer motor, Meer auto, Meer sport. I’ve renovated engine, suspension and every moving part of it. It took me over a year to have it finished. The paint works are not perfect. Probably that’s why I’ve decided to take it on our vacation trips for the last two years.
Another one is a 1983 E28 with M10 motor. Bought it cheaply from my friend and rescued from death. It was meant to be my winter car, back when I had the E30 Cabrio M-Technic II. The 5 Series has been with me for about 4-5 years now. We’ve been through a lot together.She brings me the most joy of all the cars that I’ve ever driven. My girl likes it a lot too and she doesn’t allow me to sell it. Funny that I’ve never liked the E28’s until I started to own one.
A few months ago I bought the brown E30 320i. Preface 2-doors.Original car in good condition and low mileage. She needs some love, but I guess she will be fine with me. The only thing is that I’m not sure what to do with her yet.
And my daily. I’ve been driving classic cars for a long time, every day. But last year we’ve decided to buy a “new” car. The E92 325iA showed up. I said well, why not? It took me about one month and she was transformed as I wanted. It’s so easy to customize “new” cars. You can just go and buy parts, install them and… drive. Very easy compared to the oldies.

RYE30 Racing: Where do you see yourself, and Diagonalt or Desagn in five or ten years?

I hope it grows and I can do it for a living. I recently quit my daily job to start working only with these things. I do have expanding plans and I hope it will go somehow right. It’s still much work to get it all where I want it to be. But I enjoy combining my work and passion to shape my future. The best thing is that I get a lot of opportunities to meet new, fascinating and engaged people.

Can’t Stand Your E30 – How to Assemble a Stand and Mount Your M42 Block

Another lesson in frugality incoming: We picked up an early E36 M42 engine for $250 down in Indy for purposes unknown to use at the time. It was fortuitous however because we ended up using its cylinder head after the dreaded faulty profile gasket fault made itself apparent during a July 2018 autocross. We turned in our bad cylinder head as a core-return at local junkyard where we found a good replacement and now we have a fully unfunctional E36 M42 again to make an example of for you fine fuc…folks.

Step 1: A.B.C. – Always Be Craigslisting – ALWAYS BE CRAIGSLISTING

Engine stands are cheap. Even brand new. We overpaid for our Harbor Freight brand “Central Machinery” stand. Rated at 750 lbs, it’s over-qualified, but for $40 on Craigslist, isn’t as great of a deal as we’d like considering we could get one for under $50 with a coupon and we’d have a warranty.

Step 2: Engine Stands – Assemble

The stand is essentially made up of two parts. The mounting bracket that sits in the head tube, and the stand itself. The stand is made of three parts. The two rectangular sections have the caster wheels and the other houses the mounting bracket. In our example, the two rectangular sections are already bolted together with the included hardware we received. If you’ve misplaced yours or never received any, they’re easy to replace (check your leftover nuts-and-bolts bag or buy new ones) and don’t require a specific thread because they’re slipped through simple through-holes.

After those are bolted together you can bolt the mounting bracket section to the wheels. Ours has a nut welded inside the bottom of the tubing to tie it to the wheels. Put the longer bolt through the wheels section and into the bottom of the mounting bracket section. Now you have a completed stand. If you have this stand in particular and you don’t have that bolt, it’s an M12x1.75 and approximately 100mm with a locking washer.

Step 3: Stick it to Me – The Mounting Bracket

The mounting bracket simple slips through the head tube on the mounting bracket section of the stand. Each of the four arms is adjustable. Again, if you don’t have any included hardware, hit up the nuts-and-bolts bag. These M12x1.75s might not be found as easily in your leftovers, so measure the lengths you’ll need and hit the hardware store. With ours we needed four shorter ones (about 3″), four longer ones (about 5″), and four nuts with washers.

With the block on a stable surface and all of the arms loose, mock-up your bracket thusly; bolt the bracket to the block hand-tight and then get the other side with the tube as square to the block as possible so that they are evenly horizontal to each other. Hand tighten those bolts and nuts. After that, tighten the bracket to the block fukentight and then tighten the tube section gutentight.

Put a towel down and grease up the head inside of the head tube. In your best parody of German porn, grab a friend or six and lift the block with the mounting bracket attached, and gently slide the whole thing into the head tube of the stand. Celebrate the event by sliding the swing lever and locking pin into their appropriate holes at the end of the tube. You’ll use those to lock the block in place and swing it around on its axis when necessary.

Word of advice whenever you do so, use two hands! A fully loaded engine is going to be very top or bottom heavy and will leave you in the dust when you try to rotate it. One of these we’ll get around to rebuilding our M42 and hopefully provide you with more scintillating and Pulitzer Prize worthy innuendo.

Rolling Blockout – A “Proper” Tutorial on the Deletion of an M42 Power Steering System (Part Two)

Blockages are bad if you have high cholesterol or are the case-du-jour in an episode of House. M.D. Our blockage is good though because it means the RYE30 team, doctors’ Cameron, Thirteen, and Cuddy can move onto the next scene and remove the rest of the power steering system.

After shamelessly promoting our blog to the usual Facebook haunts we received some surprisingly constructive criticism on the installation of the PS block. Some suggested that it will be more trouble than it’s worth because of the reduced ability to respond to poor steering decisions or unforeseen road hazards. Another user suggested removing valving from the steering rack to free up the internals and make it almost as easy to wrestle as when it had power steering. But the weather has taken a turn for the worse (or at least that’s our excuse) and we won’t be effecting re-installations or modifications until the spring when we’d rather be racing than fixin’. So for now, we give you Part Two of the removal of the power steering system.

Step 1: Work Smart, not Dumb

If you’re as forward thinking as us, you still have the splash guard installed. But if you’re as masochistic as us, leave it installed while you try to remove these components. Since ours is basically ziptied into place, it would have been just as simple as removing it from the enslavement of the few 10mm nuts in the wheel wells that you still hopefully have.

Step 2: There’s Seems to be a Disconnect

Most of your fluid would have drained out when you disconnected the lines from the rack, but there will undoubtedly be some left in the pump when you disconnect the banjo fitting on the bottom (no need to disconnect the one you’ll see on the side of the pump). Give it a good crank with your 22mm and be ready with your drip pan. Once that’s free, you can noodle the reservoir out through the top of the engine bay.

Step 3: No Daddy, not the Belt

Next, you’ll de-tension the belt two ways. The likelihood is that your power steering system, like ours, has never been serviced. So even if you do start off by loosening the tensioner, it might need some persuasion before the pump swings loose of the belt. Loosen the nut and bolt that allow the pump to pivot on the upper oil pan to give it a little freedom. Then loosen both the locknut and the tensioner nut on the tensioner bracket since they are all going to be removed anyway. Use a prybar or a hammer to convince the pump to dislodge. Ideally, it won’t crash down onto your face like when you’re watching hentai late at night on your cell phone in your bed, but hold it in place with a free hand anyway. Pull the belt away from the crankshaft pulley and wiggle the pump out.

Step 4: Practice Safe Splashing

Reinstall the splashguard, but only after you notice that if you’d removed the pump first, you might have had a lot more space to install the power steering block and not need to part the rack from the subframe. Wipe up your frustrated tears with the same rag you use to soak up the power steering fluid dripping down from the steering rack and go have a cream soda.

Rolling Blockout – A Proper Tutorial on the Deletion of an M42 Power Steering System (Part One)

Losing weight can be hard. Dieting. Exercising. Gastricly bypass your power steering system to shed pounds by installing a steering rack block and chucking the remaining components. Trust us. We’re MDs. Which of course stands for “Mostly Dumb.”

Our power steering delete block comes from a California manufacturer and retailer of BMW performance parts. The Denny’s coupons we asked for in quid pro quo of a felicitous name-drop are as yet mysteriously missing from our racecar budget coffers, so you’ll have to hit your favorite search engine to find out who it’s from.

It’s design is so simple that you’ll undoubtedly something like “Pshshsh. I coulda made this.” But that doesn’t betray it’s cleverness as a product likely, largely capitalized on by the manufacturer. The bleeder is a simple hex-keyed set screw instead of a more expensive traditional bleeder screw. A single passageway that intersects the banjo bolt holes to allow flow means one long straight through pass in lieu of other more complicated methods of facilitating a bleed. If it’s CNC’d from a pile of bandsaw cut lengths of mid-grade aluminum then there’s little waste lost to that process and the process of rounding the corners and running the through-holes.

At $40 a pop (when they’re not on sale for $25) they’re likely piling mounds of cash into duffle-bags and shipping them to yours, truly as sponsorship dough as we speak. By the time it gets here, we should be done installing the block and onto the removal of the offending power steering components (which will be covered in Part Two).

Because the weather is officially “fucking awful” here in the Midwest, we pulled out the trusty tent once again to shield us from the light drizzle. “Rolling around on the ground” was brought to you by “Harbor Freight Creeper” which, surprisingly, is not the guy outside the store’s front door trying to sell you coupon books with sticky pages.

Step 1: Just Lemme Squeeze Past Ya There

In a previously unreleased episode, we installed a Z3 steering rack so your experience with gaining clearance to the banjo bolts might be different. All of the related components for the power steering system are on the driver’s side of the car. You’ll find the banjo bolts you need to disconnect right below the connection of the steering shaft u-joint and the rack.

Getting these two free can be difficult for two main reasons: The clearance between the smaller, higher, 19mm bolt and the motor mount, and the blockading of the 19mm bolt by the 22mm bolt. The simple solution to the blockage was to remove the 22mm first. You can reach this one with a 1/2″ ratchet and a 22mm socket. Get your catch pan ready, because you’re going to recieve everything in the lines and in the reservoir once you let it loose.

As for the 19mm, our solution was to disconnect the rack from the subframe by the two 15mm bolts and scootch it over enough to get our working man’s 19mm combination wrench into the gap and onto the head to bust it free. Be ready to give it a few concussive blows though to knock it free because your steering rack will no longer be rigidly attached to the subframe. While the remaining goo flows, get your block ready.

Step 2: Clean Practices Will Ensure a Tight Screw

Because you’re dealing with an aluminum casted rack housing and a sealing surface, you’ll want to be extra cleanly to avoid stripping when you tighten the banjo bolts and to ensure a tight seal. Wipe any grime away from the rack surface and do your best not to wipe much (but preferably any) icky stuff down into the passageways. Clear the threads of the banjo bolts of any debris with a cloth or a spray like brake cleaner. There’s no need to pre-assemble it as seen above (apart from the loosened bleeder screw), because this is where it gets tricky.

The angle of the rack makes it puzzling to keep the crush washers lined up as you place the assembly. We recommend locating the block on the rack using the 19mm bolt and crush washers, and hand-tightening it in so that’s it’s approximately square. Prep your 22mm bolt by placing one washer on it. Back up the 19mm enough to easily slide the free 22mm washer into the gap between the block and the rack. Lastly, use your 22mm banjo bolt (with installed washer) to fish for the washer as you wiggle everything into place until you’ve hand-tightened the 22mm banjo bolt.

Don’t worry about being able to reach the 19mm. We found during the process of re-installation that there was just enough clearance to tighten the 19mm while the 22mm was in place. Unfortunately, reaching the 19mm with a torque wrench is improbable (impossible in our case) so don’t strip it! Re-secure your steering rack and move onto the next step.

Step Three: All Phasers set to ‘Bleed’

In a cosmically fortuitous turn of comedy, once you have it all screwed, you are now set up to give the courtesy of a reach-around. The official instructions guide you to turn the fully travel the rack back and forth “a couple of times” to “let any excess fluid bleed out”. Once you’re done up top, reach in from around the subframe with your 3/32″ hex key wrench and tighten the bleeder down nice and snug with some manufacturer-recommended thread locker dabbed on the threads (highly recommend by us as well given it’s not-an-actual-bleeder-screw nature).

Check back next Sunday for Part Two where we take perfectly good steering components out and then likely never test drive the car until the spring, where we’ll find that it’s now extremely difficult to wrestle the steering wheel in low speed, short radius turning conditions in the good name of weight reduction.

Spring Steel, Spray Paint, and Salvage: Our Anti-Roll Bar Brackets Get a Makeover

We have a friend named ‘Josue’ that we call ‘Sway’ for short. We can count on him to not let us down, unlike these sway bar brackets have.

Long term viability was not our strong suit in the early days of turning our once daily-driven sex-mobile into an inbred racehorse. Midwestern winter driving and near-SpecE30 suspension mix like Virgos and Scorpios. Which is to say that astrology is all made-up as it goes along and we shouldn’t have been driving this car in the winter. The parts that took the beating in particular were ones with a thin, eBay quality epoxy coating or none at all. In other words, all of them. Since we took the front ST anti-roll bar out with the fingers-crossed promise that we’d refinish the brackets, we took the opportunity to do just that in between some work on one of our significant-other’s work-and-school-mobile.

If you’re familiar enough with stock E30 suspension, you’ll notice the differences immediately. The original bracket leverages into place inside of the front subframe and then bolts into place to semi-permanently secure the bar. Because the replacement performance part is slightly larger in diameter and experiences higher torsional forces (that’s us making it up as we go), it came with a special bracket assembly that helps brace it flatter against the subframe with a large backing plate and a bracket that bolts into the original bolt hole. It also dual-purposes one of the subframe bolts.

Step 1: Safety First, Second, and Fourth (Third is Lunch)

As with any operation involving swinging phallic equipment attached to something with too much energy, you’ll want protection. Since we’re using our Harbor Freight bench grinder with included Harbor Freight wire wheel, safety glasses, underneath a face shield, behind ballistic glass would have been the wise decision. But for now, all we have are safety glasses. Gloves are generally not advised for using with rotating equipment, but since the actual bracket portion of the bracket assemblies are awkward to hold, we took the risk. Refinishing the other parts of the bracket was easier because of their straight-forward shapes.

Step 2: Stripping – Taking it all Off to Get Us Through Vocational School

Foreseeing difficulty in attacking these with the bench grinder, we took a whack at them with a nylon wheel and a hammer drill. The nylon wheel had been great at removing the surface rust on our cast iron lathe chuck because it removed it briskly and without damage to the chuck itself, but against the thick rust of our unknown-alloy steel brackets it was almost useless.

To the bench grinder we went. For the brackets, we made sure to get to the insides, outsides, and sides. This would seem obvious, but it’s easy to get caught up in this oh, so shiny metal as it appears before your eyes that it’s easy to skip the quality checks before you move onto the next piece. The part wasn’t as difficult as we expected it to be, but it did take some unusual angling to get to all the nooks on the piece. Specifically, on the outside of the bracket where it bends at 90 degrees. A tip for wheeling the smaller components like the washers and the fasteners; place them in a set of locking pliers. For the nuts and bolts, we spun them together with a fair amount of hand-tightness and ran them against the wire wheel without touching the threads. You’ll remove the special coating that accompanies hardened fasteners like these and will make them more difficult to remove the next time you need to (sometimes even with the application of anti-seize materials!).

After about 20 minutes of tiny projectiles to the stomach and a podcast we couldn’t hear over the drone of the bench grinder, everything was looking as if it had been freshly cast in a medieval blacksmiths forging facility. Blacksmithery? Correct us in the comments. Someone. Anyone. Please read our blog! Anyway, on to paint they go.

Step 3: Epoxy Paint Me Like One of Your American Anti-Roll Bar Brackets

Previous projects on our Alfa Romeo Spider left us with more than enough black epoxy paint. We double-fisted each pair of components on some bailing wire and coated each one three times. Normally, we wouldn’t coat the threads of a fastener with paint because it can negatively alter those threads capacities to have torque applied to them. In other words, they won’t tighten no good no more. But since we had the nylon nut already covering the only area of thread that it would ultimately be engaging, we went ahead and painted it with the intention of it being a rust preventative maintenance.

While we let them air dry between each application, it’s important to let them cure for whatever period of time is suggested on the back of the can. Since we won’t be installing them again any time soon, we let them rest on the bench to do the requisite curing, hoping all the while that they spring to life the moment we close the shed door and go on a Toy Store like adventure in the time it takes us to eat, sleep, kiss our loved ones (and pets), and return to the shed for the continued torture of not being inanimate objects that become sentient in the absence of people.

We hope you had a happy holiday season and that you slayed many no matter what belligerent you fought for in the war on Christmas.

Where Will You Hide When the Revolutions Come? A Proletariat’s Guide to Tachometer Installation

Cowering behind the steering wheel, you wonder if with all of the abuse you’ve reaped on your engine, will you be held to account when the guillotine (or ‘clutch’ in this metaphor) finally drops?

Beyond the faded paint, and rusted door corners. Beyond the hibernated, storage-unit affair of its interior.

Underneath the makeshift sunshade, used to protect only the most highly sensitive electronic equipment…

…lays a digital tachometer.

A purveyor of the most vital information besides water temperature, engine speed is an essential diagnostic measurement for maintenance and reference for track driving. Our preference is for a digital, as opposed to analog, readout of that information. We found a home-grown LED counter and sweeping shift light combination called the “SL10” on eBay from a French seller (and designer) named rgtracetech883 with a tonne of functionality for it’s size and price. But you can use any you prefer as long as it can read a 5 volt or higher pulse signal and be powered from a 12 volt system.

Even if you only have a tentative understanding of electricity, this really isn’t that hard! We’ll try not to drone on about theory, but getting you to understand your car (whether it’s an E30 or not) is what we’re here to do, so no promises. In this case, we’re going to try not to bore you with the installation of this simple power/ground/signal tachometer.

Step 1: Unfuck the Cluster

If the first word you think of after “cluster” is “fuck” then you’ve come to the right blog. We pulled this entire dashboard out for what was ostensibly no reason once, and in subsequent efforts, just the cluster at least a dozen times, so a few steps might be missing since we’ve left a few things out to streamline the process. As you’ll see in the picture, the plastic trim panel that hides the manufacturing nether-regions below the cluster has already been removed (and misplaced). After you’ve navigated to a better resource and figured out how to remove the outer-most panel, grab a PH1 screwdriver (or bit, extension, and impact gun) and remove the four screws imprisoning the bezel. Once that’s removed, there would normally be two more screws holding the cluster itself to the ceiling of the dashboard. Pop those out and get to wigglin’.

It’s in there pretty tight. This is normally where we’d say “that’s what she said” but our adjacent German-language erotic Scott Pilgrim fan-fiction blog only comes out once a month and we don’t want to spoil anything for you by going on a tangent. We found that if you pull up on the bottom, and swing it in towards the front of the car, you can use the space inside the dash to point the face at the floor and eject it like a DVD of Paul Blart: Mall Cop.

Here’s the part where we could just walk you through the details to make it easy for you, but knowledge is power, and power is something you’ll need when you have a 238,000-mile old M42-powered BMW.

Step 2.0: The Basics

The M42 tachometer is aesthetically analog, but is technically digital. It receives a digital signal that gets translated and represented by a sweeping needle across a handsome 6200 RPM redline face. That signal comes in a pulse directly from the computer. That pulse is a beat of 5 volts so-many times per second (where in the off-beat it sends nothing, like turning a light bulb on and off). That beat of so-many pulses-per-second is the hertz frequency or just hertz. So if the computer is sending 5v pulses 20 times per-second, that’s a 20 hz frequency. In the case of the M42 owner specifically, those 20 count, 5v pulses-per-second, represent 800-900 revolutions of the engine per minute.

Step 2.1: All the Right Signal

Now that you’re a little more knowledgeable, it’s time to test that theory on some of the wiring behind the cluster to confirm which wire you’re going to circumcise for the good of your new tachometer signal input. Remove the blue connector and disassemble it as shown in the pictures. Since we’ve already installed ours, you should be able to tell that the black wire is going to be the one sending that 5v, 20hz signal from the computer. Start your engine so you have a frequency to read and place the setting dial of your multimeter in the “Hz” position. With your black wire still attached to the blue connector, you should be able to stab the red lead of your multimeter down into the top of the harness and hopefully contact the bare metal of the wire, and complete the circuit by attaching the black lead to any metal that is attached to the frame of the car. Grounding circuits out to the frame is a concept we won’t go into here because we have to get back to the Planet of the Apes marathon and there simply isn’t time. If at idle, you see “.02 khz” (move the decimal over a few spaces and you’ve got 20 hz) come across the screen then by Jove, you’ve done it! Splice into the black wire and lead your new wire away from the cluster to a location that will let you hook it up to your new tach. Our old tach no longer worked, so we opted to cut it out completely before re-routing it to the top corner of the dashboard on the driver’s side. Turn the engine off for these next steps or you’ll risk turning components of your new tachometer into tiny mushroom clouds.

Step 2.2: POWER!

With the hard part over, and depending on the state of things in your car, you are now tasked with the trial of finding a way to power the damned thing. With most of our HVAC control and radio missing, we had a treasure trove of wires to choose from to give life to the tachometer. Specifically, one that would gain power when we turned the ignition to ON and would invariably lose power when we turned the car off. We determined that by testing the voltages of wires as we turned the ignition ON and OFF. A tedious process, but an effective one. An easier option would have been to defer to a repair manual with an updated wiring diagram, finding a circuit that met our needs, and confirming with our multimeter. Run that power line from its source to your digital tachometer and move on to the next step.

Step 2.3: Don’t forget the little people – Staying Grounded

Remember when we said we didn’t have time to go into series circuitry? We still don’t have the time. Battle for the Planet of the Apes just started and we’ve already missed the crash landing of the spaceship into the Forbidden Zone and we don’t want to miss Taylor’s first meeting with Nova. Oh, Nova. But we will tell you that it’s not like a battery. You don’t have to route the ground cable back to the battery, it can simply be grounded to a nearby bolt, as long as that bolt has an all-metal path back to the frame.

We’ve learned to always anticipate that things will be removed for maintenance or upgrade, so instead of crimping or soldering the tachometer directly to our newfound power, ground, and signal wires, we snapped them together using parts from the same connector kit we used to adapt the oxygen sensor in our exhaust manifold blog entry from last week.

If you haven’t already, go ahead and plug everything in and give it a test! If you see numbers that make more sense than the timeline of the five original Planet of the Apes movies, than you’re now basically an electrician. Go out into the world and remember that it’s not the voltage that’ll kill you, it’s the amperage. Luckily for us, our Hitachi Magic Wand only pulls about 1.5 amps at the most. Don’t ask us how we found that out.

Now get out there and use that new digital tachometer for good by racing your E30!

Exhausting – If It Ain’t Broke, Break It: How to Replace a Broken Exhaust Manifold with an even Broken-er One (Part Two)

We will never be exhausted in our attempts to exhaust the potential of using derivatives of the word “exhaust” in our wordplay. But we sure are exhausted from working on this exhaust. Plainly put, “Hi Exhausted, I’m Dad.”

We apologize for the cliffhanger in the last post. Years of surprisingly good, serialized television has made us incapable of just wrapping up a story (thanks for nothing Breaking Bad). After a bit of manual machining with our battery-powered drill, set on the low gear and with light and continuous trigger pulls, we opened up the mounting holes on our stainless steel manifold’s baseplate so that it could now freely mount to the head. Poor, or no quality control left us with a manifold that was off by several millimeters so mounting was impossible.

Once it was in place, we go to tightening the nuts and studs. A good practice when re-using hardware (that’s safe to be re-used), is to clean all of the surfaces and use anti-seize or thread-locking materials. If you’re comfortable with the use of a threading tap, find the right one (because if you don’t, you’ll be living a popular South Park meme format), and give each threaded hole a good what-for so that your not fighting any grime, dirt, dust, or chips that may have found their way inside.

With most of the nuts and studs hand-tightened, we ran into accessibility issues particular to this manifold. The bottom nuts on either side of the cylinder-two piping were impossible to screw with our power tools. However, being familiar with the plight of un-powerable (clearly sic) bottoms, we resorted again to the technology of the proletariat, the combination wrench. Not being so foresighted as to have ever obtained a ratcheting 11mm combo wrench, we toiled away at the two small nuts with a fever, knowing that the sooner it was over, the sooner we could get back to talking trash about Breaking Bad’s younger sibling, who won trophies, but could never seem to really make mom proud, Ozark. With the last two snugged, we tightened everything else in a sort-of star pattern to evenly apply pressure across the manifold as best we could.

If you’re lucky, the old oxygen sensor came out with some gentle persuasion from a rented or purchased oxygen sensor socket and some propane heat around the bung. If you’re even luckier (like us; suckers), you have an uninstalled sensor sitting around in your spare parts bin from a Miata that you should have never sold. Why did you sell it? Because you didn’t have the space? It still drove. You could have parked it at a friend’s house until you had…Don’t worry about that connector that doesn’t match. We happen to have a small case of 2-8 pin male and female connectors for just these occasions. We bought it online a couple years ago because, who’d’ve thunk, splicing wires together with electrical tape in many ways proved to be a sub-standard repair. You can go to any hardware or automotive store and get a kit like ours, or just get a single connector set to replace the ECU and sensor sides respectively. With a new connector and matching thread (most oxygen sensors regardless of application seems to be M18x1.5 pitch thread), we plugged it in at one end and tightened it down in the other. Unless you have more exhaust work to do because the layout changed so drastically, as ours did, cross out the line on your to-do list that says “Fit Stainless Steel Manifold” and then go out and race your E30 (or whatever other peasant-mobile you’ve been working on for ten or more years*).

*Note from the Editor (who also happens to be the writer, media liaison, intern, and barista) We’d like to take the blog in a slightly new direction. Focusing on E30 specific content is always going to be the purpose of this blog, but we want just as many people to race their cars as we want every E30 owner to race theirs! Our writing style will change a bit to be inclusive to the learning hobbyist so we’ll probably spend more time on tool use, automotive theory, and safety, and other team members have their own projects that will be guesting on the blog. But it will mostly always be through the lens of our ~~rusty~~ trusty sedan.

Better on Vinyl – How to Apply a Windshield Banner

We have many fantasies. Most, if not all of them, could be shared with you here, but they would take away from the focus of this article. We’ll save those for our other blog, “What Macaroni Shapes are Best When Bathing in Tubs Full of Classic Italian Pasta Dishes?”

Today’s non-carbohydrate fantasy involves the awakening of something inside our childhood spirits. The dreams of those 11-year-olds, sat in front of standard definition televisions, fighting for their lives on that final Gran Turismo Super License test, have come to life. We are adults now, with wallets and eBay accounts. We now have a vinyl Gran Turismo windshield banner! Life is now the realest driving simulator!

All the “greats” have and had them. The words adorn instantly recognizable cars and events like the Pikes Peak International Hill Climb and the Nissan GTR Nismo GT3. Now, finally, it graces another legend in the motorsport community; our 1991 M42-powered BMW 318i!

How can you grow up to be like us, you ask? Follow these steps and be prepared for the onslaught of highway thumbs-ups and on-the-spot marriage proposals from women, and men, because you’re going to be swimming in them thereafter once you’ve hit the road.

Not Pictured – Tissues for Wiping Away Tears of Joy

Tooling is pretty light on this one. Especially compared to what we needed to install the flux capacitor. We’ll go over the tools you’ll need from left to right and then up top.

1. We had a small felt lined squeegee left over from a long-ago attempt to recreate a Marlboro theme on our hood, but you can just use a credit card. If you don’t have one of those, use your favorite adult video store loyalty rewards card. It will likely work much better because the felt lining wasn’t as aggressive on the bubbles as we’d have liked.

2. We used an old putty scraper to remove a sun-faded car class sticker from an event we ran at the Autobahn Country Club over the summer. This is another tool that could be successfully substituted with your adult video store loyalty rewards card.

3. In your mind’s eye, picture a can of brake cleaner or Goo-Gone next, to help you get all of the left-over sticky residue free of the glass.

4. (Imagination time again) Painter’s tape will help you keep everything in place while you line up the banner.

5. Use a smaller blade like ours if you can because cutting away the excess is going to need a precise hand, unencumbered by something bulky like a carpet cutter.

6. Use the microfiber and towels to clean the surface area that the banner will be affixed to.

Scrape the Pain Away

Cleaning the windshield is likely going to be the easiest part, but arguably the most important. Bubbles can form around debris stuck underneath after a time, even if you manage to completely squeegee them all away initially. It’s the simplest part of the job to get right, and you wouldn’t want your mother to be disappointed in you again, would you? Especially after that stunt you pulled at your high school graduation?

If you have something as dreaded as what was nothing more than a package label stuck to your windshield, scrape as much away as possible with something that won’t scratch the glass beneath it. Use some brake cleaner to apply a fatality to the remaining goo.

Now that you have a flawless windshield, line up your decal as best you can. We used the bottom seal of the windshield as a reference by making a mark at its center (green squares in the picture below) with a permanent marker. We found the center of our banner and matched it with the centerline mark (green) as best we could. Then from either side of the banner (upper yellow marks), we measured from its bottom to the bottom seal of the windshield (lower yellow marks) to make sure there were even distances. Throughout, we used some painter’s tape to temporarily hold the banner in place as we moved it around.

This is the tricky part. With the banner held in place by the painter’s tape, pick a side of the car, and as best you can, with a partner, pull the backing away a few inches and start applying the banner. Once you make the initial contact, start squeegeeing. Squeegee in the same direction as you are applying the banner. Get most of it laid down with this method and then worry about squeegeeing the edges. Don’t push too hard into the corners because you might cut into the vinyl. To make that step easier, cut away the excess, but leave yourself about two inches to grab at. Gently, (petting-a-kitten gently and not lock-the-door-and-mute-the-sound gently) pull that two inches up at a 90 degree angle to the glass as you push the vinyl into the corners with your edge.

Once you feel satisfied you have a fairly bubble-free and cornered banner, grab that small cutter. We recommend that you do this in two or three evolutions. Cut away 90% of the excess in a slow and steady pass. Be careful not to put too much weight on the windshield and bust it because you’re too focused on edging. If you see what we did there, go ahead and pat yourself on the back. In your second or third pass, cut away the excess right at the intersection of the seal and the glass. That should leave you with an aesthetically and nostalgically pleasant vinyl banner!

Go out and race that E30 already!
