1st off i would change out the screen name from maybe to something else..
2nd with stock turbo is goos for about ~15 psi.. anymore than that and its blowing out hot air..

AHHAHAHHHA yeh i should have used a different name, its just the name i use on 240sx forums bc i got my motor out of a wrecked car in the area and i heard the motor had a cracked head or something, so i just used "maybe" in my name cause the motor may be good, but it is, so i guess i should change it

I agree with Dousan, get some injectors!
