    MasterC17's HPDE/Time Attack Track Car (Re)Build

    It's nice to be back on some M3 forums. Some of you may remember me/my car from back in the M3Forum.net days. RIP. Sad to see that go, and lots of great information and builds with it. Fortunately, I was able to recover most of the information from my car after searching Photobucket, etc.

    It's been a long time since I've worked on or driven this car. I purchased it in 2011 with ~105k miles on it - Titanium Silver/Black with SMG. Quickly converted it into a track car and ran it from 2012 through 2014. Car ran nearly flawlessly, but at the end of the 2014 season, I had an issue with the SMG shifting slowly.

    Then, I pulled the motor out of it to use as a donor for another M3 I had. Next, I decided to send it to my buddies body shop - the paint wasn't bad but the carbon stuff needed some TLC and I always really wanted Alpine White.

    The body shop did a complete inside and out (engine bay, door jams, etc) repaint with new VIN stickers. They installed a carbon roof onto it. But, it took a while. I finally picked it up in 2021. And in just these past few weeks, with a few other project cars gone, it is finally time to get this car back together!

    The chassis now has about 110k miles on it. It's incredibly clean, no rust anywhere (Florida car). The donor motor has 80k miles on it. It had an issue with the VANOS bolts that caused timing to jump and two intake valves to hit on Cylinder 6. I just dropped the motor off at the machine shop for a full rebuild.

    Here's the planned build, most of which is carryover from the previous iteration. Main changes are the plan to move to a 5-Speed ZF, and just a general refresh of some of the older components.

    Got the front suspension/subframe/steering rack apart today. The control arm ball joints did not want to come out of the knuckles. I finally got them out, but the rubber seals didn't make it. Not a big deal, since I'm fairly certain they had never been replaced. New ones ordered. Otherwise, got some cleaning done, touched up the paint on the subframe, and swapped in a Purple Tag steering rack! Including a pic of the interior.

      Welcome back and very cool build! I'm curious about the "5-Speed 320Z Transmission". Is that similar to the E36 5-Speed? I'm not familiar with that conversion.

        Thanks! That's correct - it's the same thing. The 95 M3 used the ZF "310Z" and the 96-on used the "320Z", in the M3 and several other E36/E46/Z3 models.

                Heck...I think I knew you from the E46Fanatics days. LCI E46 330Ci, right?

                Nice color change! I don't know why but I love the way alpine white E46 M3s look. It's a subdued body style with a classic color I guess.

                If you have the S54 JB Racing flyheel then you need an E46 M3 pressure plate with the E34 M5 clutch. I've always wondered if I could bolt up an E36 M3 flywheel to the S54 and then use an E36 M3 pressure plate which has more options available. I think Sachs makes an HD/non-SAC version of the pressure plate for the E46 M3. The issue is the E36 and E46 have different diameter pressure plates.

                Details on the side exit? Do you the have the total length of the piping?

                  Yup - that was me!

                  I totally agree, Alpine White is just a great color. Tentatively planning to use an E46 M3 ACT lightweight flywheel.

                  I'm not certain of the total length of the side exit, but it's using a Bimmerworld Y-Pipe to 3.5" tubing which is probably about 2ft in length or so. Only one exhaust tip is used, the other is for show lol!


                  Some updates!

                  The MK60 swap is basically finished, I just need to do the wiring now and get fluid in the system.

                  The Moton's are installed - once everything else is done will focus on corner balancing, alignment, and damping adjustments.

                  Got a lot of the exterior bits back on - tail lamps, wing, trim, some glass, etc. Still a bit to do there.

                  Pedals are in. So manual swap is probably 1/3 of the way done.

                  Motor is nearly complete at the machine shop, planning to pick up next week.

                  Still a lot to do, but making progress!

                    Here's a closeup of the MK60 swap. Tapped into the existing rear line connection points, but ran new lines everywhere else. These are not easy to bend!

                    Also a picture of the current wiring (mess). Will be splicing in the MK60 Connector and cleaning everything up, and deleting the things no longer needed (SMG, EWS, etc).

                      Small update - received the Rotora Calipers back from powder-coating. Are they the most fantastic brakes on the planet - no. But, they worked perfectly fine before, and given the car is ~2,600lbs and won't be making more than 350whp, it won't take a mega amount of brake. One advantage is that they are very light - I'll post final weights later but my recollection is ~5lbs for the rears and ~8lbs for the fronts. Paired with CSL rotors and good pads it's more than enough. Will be getting all new hardware as well.

                        Awesome updates. Do you mind posting some pics of the steering column mounting to the roll cage?

                          Nice work!

                          Like the MK60 swap. Job is a pain on a street car, but probably not as terrible with the engine and interior out. Good call on tapping into the rear lines, making new rear ones was easily the worst part when I did mine.

                            So what you're saying is track guys have it easy?

                            Haha...actually we do. I helped someone do a valve adjustment awhile back on a garage queen. I looked at his engine bay and barely recognized anything. I was like...you really need to take all of that crap off? Takes 5 min to get the valve cover off on my car.

                              Lol easier is probably more accurate. Soo much stuff in the way on street cars
