    95 E36 M3 S50 HPDE Car Build Journal

    Bought this car June 2019. It sat in storage for 3yrs never really doing anything to it. Bought it with TCK DAs already installed with 400/500lbs springs. 165k on the motor and chassis.

    Immediately sold the DS1s and put on 17x9 et42mm ARC-8s with 245/40 RE71Rs. I paid to have the cooling system updated with aluminum rad, aluminum tsta housing, some hoses, spark plugs, valve retainers/ keepers, motor mounts, oil change, brake fluid flush, stainless brake lines, MOMO hub & steering wheel, and then I went straight to the track.

    I also figured out that if I want to keep running HPDE’s, I would have to learn to work on this car myself.

    Took it to 8 track events this summer, burned through 2 sets of tires and found a blown head gasket after the final event. In between events I replaced/installed the shifter bushings with OEM, guibo, heater control valve, Rogue trans mounts, front calipers, brass guide bushings, clutch pedal & bushings, diff fluid, MTL fluid, Motion Motorsports underpanel, AC delete, and a couple more things I can’t remember.

    With winter here, kicked things off by getting the RTAB pockets reinforced at MWorks Garage in Cincinnati.

    Disassembled the front end in preparation for my Black Friday purchases.

    Front subframe down awaiting Condor reinforcement plates.

    Head removed to replace gasket, Vanos seals, and being sent off to Autohead Performance for a freshening. Piston bores still show hatch marks.

    Just got it back! 3-angle valve job cut on a Serdi, pretty cool!

    5DB4856C-2D47-4BD5-88D8-E619B6163EEC by D S, on Flickr

    Cams back in and ready to put back in! Most DIYs say 11ft-lbs on the cam cap nuts... but Autohead Performance was adamant they should only be 6ft-lbs. So that’s what they got.

    Got the valve cover back from powder coat. He did it in regular black first and then covered again in wrinkle finish black to try to hide all the imperfections. Still not perfect but much better than what it was. Now trying to decide if I’m still going to put the engine plastic cover back on or not.

    Did a few things while the front subframe was out. Safety wired & red Loctite oil pump nut, Z3 sump pick-up, and a fresh oil pan gasket.

    Dropped the rear subframe as a whole. Was easier than I thought.

    The key to getting the subframe bushings out is to heat them up on the outside just until the rubber starts to sizzle. About 2min with a MAP gas torch. You’ll know you’ve heated too far because they will catch fire. Then just give them a bump with a hammer.

    All cleaned up with Condor bushings.

    Driveshaft freshened with a new centering bushing, CSB, and coat of paint.

    A lot of goodness down here... a bunch from the junkyard. From the junkyard: Z3 031 steering rack, Z3 X-brace, and 325is sway bar. New: Condor front subframe reinforcements, Condor FCAB bushings, and new oil pan gasket. That oil pan used to be as dirty as the transmission.

    Looks good. Should be a big difference come spring when the tracks open up again.

    Baffle the oil pan while it was out? Any oil cooling installed? Consider adding an oil cooler and accusump setup and that engine should stay happy for a LONG time. Also consider hood vents if this is a track car.

    Once I had a happy cooling system/engine, the s50 was dead nutz reliable for me on track. Love the color combo.

    All things I will consider. But this winter was to just get reliability up and anything while in there taken care of. Except the oil pan baffles. Some mods I can do in between events and when the car fund replenishes itself a bit.

    FYI, both Bently and BMW TIS (Technical Information System) say 11 ft-lb for the M7 cam bearing caps

    Love that the cylinder walls still have cross hatches at 165k. Amazing.

    Have to admit that I’m a little sad the interior is gone.

    Ben Sipson bar fitted today. There is a compound angle where the floor mounts go so I put the bar ahead of that angle. When I did, all 4 mount locations touched with a little body weight on the bar. I drilled one hole in each plate and tightened it down before drilling all the rest.

    Would love to see more pics on the bar install. Just ordered mine today from Ben. Doing the X brace and harness bar set back.

    Yes, will do, only fitted the bar and drilled the holes. I drop it off for powder tomorrow. To install, the foot needs to pass in front of the shifter, between the shifter and center dash. The other foot will kinda go under the door until it’s right up to the rocker panel. I’ll get picks when I do the final install.

    Wire is cleaned up as far as I will go. Just waiting on the split wire loom I ordered. I can’t take the fumes from Xylene and Goof Off so the only sound deadening I removed are the pieces that somehow interfere with the roll bar installation.

    Took out the steering column safety bolts in anticipation of lowering the wheel 1/2” to 1”. Silly me thought it was a nut so I figured I’d drill half out. Only to discover it was actually a bolt head. Thankfully the chisel technique still worked despite destroying most of the bolt head. Waiting for my seat and side mounts to arrive before finalizing the spacer.

    While I had the drill out, figured might as well drill out the steering wheel lock out.

    I just gutted my interior and just put the dash on the garage floor as i type this. My wiring looks like a rats nest. I so dont know what to do. Most people are saying to gut it and start from scratch. But i plan to keep this drivetrain for now and do a swap this time next year. I cNt see messing with the engine harness but i want all the body harness (except the lights) gone...... what to do.

    The only wires I completely removed were for the radio/amplifier. The rest I cut, taped, and removed the fuse where possible. I kept everything to keep it street legal. I kept the HVAC black box too. Here’s what my fuse box looks like now. This is an HPDE car that is trailered to the track but driven to the mechanic for alignments, tires, etc. If it was a race car, I would look into completely thinning out the wiring including the HVAC, window switches, hazards, etc.

    Got my Bayside Fabrication (Ben Sipson) bar back from powder. Don’t know if it’s good or bad but paid $85 cash for gloss white.

    What I’m trying to show in some of these photos is how it fit before bolting it down. Less than a 5mm gap shown with 5mm Allen wrench at the passenger front mount, which was the worse one.

    Here it is all tightened down. Trying to show the gaps on the sides and the top with no sunroof cassette. Make sure you tell Ben you deleted the sunroof.

    Lastly, you may have noticed that I tried to cheat the whole bar toward the driver. It’s slightly offset by 3-4mm. But that’s not the bar or Ben’s fault. I work in the automotive body-in-white welding and assembly business... the tolerance stack up on cars from the floor pan to the roof is typically up to 10mm. So not bad for a “production” piece. Overall extremely happy. Any better would need the bar at the shop for custom fit up and measurement.

    I had similar fitment issues with my bar. I also removed the sunroof, so there is that same gap between the bar and roof.

    Man this looks good. I have been wanting to a cage in mine but when I moved up here to Louisville I didn't see much SCCA racing going on. What track are you running on up here?
