11-26-2025. I got the rear tires mounted on the wheels and balanced, and I was able to attach one headlight bucket and then started painting several coats of filler primer for deep scratches. The bucket has deep scratches in the metal in the bottom of the scoop portion, so this will get a start on filling them, and then I will put some glaze on there and sand it smooth and sealer prime it before color and clear. The other headlight bucket, after sandblasting revealed a crease in it, and I don't have the moxie to want to fight and fix a crease and make it look good, so I ordered up a reproduction bucket. I then got a call from J&S Polishing, and ran down there and picked up my intake and valve cover. Pics heavy.

I just found this site as i started building my Z, and will be following along as you finish up this project. We are on somewhat similar paths so this will be fun to watch it come together.

Wow, great progress! I love the cantilever design on the rear suspension. A few guys here have previously designed their own custom cantilevers; but AE is the only vendor that I'm aware of that has ever "mass produced" a system like this. Really interested to hear your feedback on how the whole TA package works once installed. Is that the final resting place for the fuel cell? If so, are you going to have a way to isolate it from the rest of the driver's compartment?

Lower than 100kpa at WOT could be elevation too, if this log happen to be somewhere higher than your used to logging take that into consideration aswell. Id think where you have the filter should be a good spot for air. unless the aero is really creating a negative pressure spot for some reason. If thats not the case id think your on the right track with looking at valve train stuff. But don't rule out the sensor itself or the hose feeding it.

Not super sure. At 100% throttle, the MAP sensor is really slow to respond and only climbs to 91.8kPa (atmospheric should be ~100). Here's a log at a good period of full throttle in 4th gear. Just pulling super lazily. This motor has always behaved like it's getting enough airflow. With 3rd gear sorted, I should be able to get it back out and do some testing. One theory is that with all the front end ducting, the motor is pulling a vacuum in the engine bay. Another is that the cam timing is off and needs to be tweaked. I think I might pull the front cover off and see what's up, and if there is anything obvious there before I get back out for next season. I've done cylinder temps, compression checks and leakdown and everything seems happy enough mechanically. Just something silly happening somewhere in the system.

Got a lot of the rear track attack kit put together today. It went together pretty well, their videos are very helpful. Only minor issue was these lock washers being too big, just ground them down a bit.

What did you get, the Pro Touring kit? I do like how the Apex suspension looks and I heard a lot of good things about them. I also picked up some parts for myself to try out. Modified S30 Z’s are rare in Europe and once with anything more the coilovers even more so I’ve never seen the Apex suspension myself. I will eventually move down the new Retro Mod line as I want to keep the stock drivetrain and R200 diff but for now I just got some nice upgrades that give me the adjustability I need. - Front fender brace - Frame rails - Rear strut brace - Front control arms - Steering knuckles - Front crossmember - Upper steering rack clamps - Rear control arms
