how much boost to u think i could push on a stock b20?

 

there are several threads on here of b20's making decent power. One of the people made 277 hp on 15psi. There are also alot of threads about how weak the sleeves are and how it is not worth it. Just giving you both sides. My friend actually is running a b20 turbo and the motor pulls good and runs strong. No mechanical issues yet, besides a pesky ignition misfire. I would say as long as you dont plan on going crazy it should hold fine like 10 psi daily. But who am I to say . Good luck
