Normal boost for Turbo??

How much boost do most people with turbo integras run? I am seriously thinking about getting a turbo and the kit i pasted under my other thread "is this turbo good for me", produced 150+ HP running 3psi of boost. Is this fairly low for the average? How much more power could I make if I can run like 10psi. What boost produces good power safely??

average is around 6-9psi. 3psi is a little low but definetly safe. after about 10psi you start getting into the 'danger zone'. I don't have any experience with turbo integras so I can't give you a specifice pressure for that application.
