i just bought a SOHC greddy kit. the question is what is the highest psi can the turbo take? i know my car can take about 10psi daily with proper tuning.

EDIT: oh yea i forgot, i got a y7 and if i add a y8 head and z6 ECU will my CR be too high to turbo 10psi?

you shouldnt worry about the turbo as much as you should worry about the survivability of your motor.

i just want to know whats the limit of my turbo if my engine is properly tuned and such.

1 trillion psi I think the most it will boost is like 13-14 before it starts to spike. above that I doubt it will make any more power at all.

so i guess turbopanda's piston and rod combo would be great for the greddy kit.

Ivan

yeah I wouldn't see why not. I use to have the greddy kit back like 3 years ago. I loved it. good for the price I would say. if you have a few more dunkets and have some ingenuity, I would piece my own kit.

they do say that the b16 rods are no where near forged. but at 15 psi at the max, i think the package can take it...anybody disagree? how much whp will i expect te greddy turbo at 15psi?

Ivan

i would run it at 15 psi. it would cause boost spike. I would say it would be safe at 10 psi tuned. have you posted this in the FI forum? Theres lots of experienced people in there.
