It's still running strong. It was really lean at 7 psi but at 6 it was the high end of what my tuner called safe. I only left it at 7 psi for a couple of days and then I got scared because I started detonating. I've been running at 5 psi everyday now for almost three months. Almost 8,000 miles and no burning oil, a little bit of lifter noise (but who wouldn't have that at 205,000 miles), and the tranny is still holding strong.
I borrowed some things from a friend that he has to wait for some money to put on his car.
Switched to JWT ECU, 370 cc injectors, Disco Potato, z32 maf and retuned:
5 psi: 151 whp/146 wtq
7 psi: 168 whp/159 wtq
10 psi: 214 whp/191 wtq
12 psi: 228 whp/208 wtq (Trans started slipping)
14 psi: 237 whp/ 214 wtq
18 psi: 258 whp/221 wtq
at 18 psi we had maxed out the injectors and the FMU and the exhaust was a major restriction. I also just about fried my transmission. It was really lean (13.7-14.1). I would not recommend trying this.
If you compare this to Wes's car you can see what a difference the headwork makes.
I've decided that I want to continue the work on the GA just to see what it can do with pistons, rods, etc. I want to blow up the engine in style. I'm also going to do an auto/manual swap.
