I'll dig up my pics. My car is sitting in a friend's barn in Missouri. I had no way to bring it back, and no room for it here. It's strictly for autocross.

When I get home tonight, I'll dig up the photos, but PM me if you have any questions about the car. A friend of mine had a 240Z he used to autocross. He was the master mechanic for a Toyota dealership in Kansas City. He bored his 280Z motor 50 over, had some valve work done, had flathead pistons, 240Z heads, and a 5-speed manual from a 280Z. The Z-car weighed only about 2300 lbs, compared with my Supra which was HEAVY (3700? I believe?!). It's all about power to weight ratios.

I had a 1989 Toyota Supra Turbo (Intercooled) with 292 HP (HKS 2.5" exhaust, variable boost control, 17-inch wheels, soft Yokohama tires, Eibach springs, aftermarket front stabilizers, K&N intake and smoothed out intake runners. We took our cars to KCIR dragstrip. I went through the 1/4-mile at 14.33 secs @ 99.11 mph, but he went through at 14 seconds flat 97 mph. He jumped out ahead by two car lengths at the very beginning, and I couldn't catch him at the end. He eventually switched to the 4.10 gears and was able to reduce his 1/4 mile time to 13.5. Unbelievable for a tiny normally aspirated car.

If you don't want to dish out the money for the Mikinu carbs, you can get a hold of the stock SU carbs that are incredible! Cylinder head and piston choices will affect your compression ratio, and different head designs have different ports. Some have square ones, others have circular ones.
