how much boost /?
 

hey i was wondering how much boost can i run with stock sleeves...but with forged internals???? btw its on a b18a1

depends on the turbo....15psi is the most commonly thrown out number....so i would say 15psi really well tuned would be okay...

im guessing a t3/4 turbo at 10-15 psi would do?...also how long could i expect my block to last?

you can throw more boost at it than that, do a search and you will find a stoopid tuned b16 that made upwards of 450+ whp on stock sleves. Im sure it was over 15 psi.
