Boost question

Hey guys, I wanted to know if anyone knew how much boost a stock turbo and motor can handle before problems. My boost is around 30 - 32 psi. I just want to make sure I will not blow a head gasket or waste the turbo. I have an over boost annihilator on it's way, and I wanted to tighten up the waste gate for a little more boost. Thanks for any info.

On a stock turbo, 30 psi is the limit. Not sure how your getting 30-32 out of yours, I can barely hit 27 on a good day. You wont need to worry about head gaskets untill 40 psi IIRC

From what I know, 25# is the point that is safe for the stock turbo. Anything over this, the turbo is starting to hurt.

I wasnt thinking when I posted my first post, Rick is correct 25 is the safe number.

I meant 30 is the most Ive seen/heard on a stock turbo with the wastegate unplugged and a boost fooler.

That's not good. I was ready to tighten up my wastegate to try and get some more boost. I guess if I want more I am going to have to get a new ball bearing housing. Can you beef up the stock turbo to handle more them 30 psi?

1.0 housing? at that rate tho u'd be better off investing in a van turbo and a ebpv delete... a 1.0 should reduce drive pressures but i could be incorrect in this thought
