im no stranger to all this just this problem in particular. my last car was lsv 95 dx hatch with gsr head and had eagle rods probe industries pistons well you know the roster. made 483 on 18psi with a precision turbo and 750cc injectors and 307 at 13psi tuned on crome gold. i wanted to try all motor this time for the challenge of it all. this one pulls awfully hard compared to my first all motor setup with p30s back in 03 tis why im ruling out everything. i hate to pull it all back down running this good but i hate smoke!
