2.5 inch turbo back exhaust, 8lb flywheel, 2.5 inch cold air intake with K&N 3x8 inch cone, Walbro 255, exedy clutch, ported manifold from a 95, VPC, S-AFC, Profec A Boost controller. I have bigger injectors, but I havent bothered putting them in yet. I wanted to see this thing running and actually starving for fuel. The profec and S-afc are disconntec as of last night, and still no change. The motor jsut does not want to run under boost, and as thee boost get to 8 psi it becomes verry erratic bouncing between 8 to 10psi. I'll have to add a new log later I cleeared them all.
