How much boost is it safe to run on a b16a with all stock internals?

 

7 or 8 psi

 

All depends on the tuning. You could run 5psi and blow the engine up. People have made close to 350whp on a stock internal b series but the tuning needs to be spot on. I would say between 8-12 psi would be good as long as you have good tuning.

 

If I were you, I would go here:

They had alot of the information I was trying to find out and bunch of other stuff I never really thought about.

I ran @ 8psi conservative street tuned by XS Engineering on an Apexi Power FC.

 

Wrong link above. Was trying to help some with a nitrous decision. 7-8 psi is good.

 

I used to run 8psi, but know i'm runnig 10psi. Its all in the tuning.

 

ran 10psi in all gears with stock internals. everything was fine. im rebuilding the engine so it will be safer!!

 

nsxmatt ran 10psi in his old hatch, on stock internals, he ran in the 11's on slicks, the car was always his daily driver and the car never once broke down on him.

here is a link to his car.
PS the car is no longer for sale

you wouldn't happen to know how much he got that turbo manifold for or where he got it would you?
