Turbo psi/hp ratio, 5sfte questions Options

[urbandork]

First off let me say i have searched and gathered lots of info but i still have some questions as sometimes the truth was confusing.

First off what’s the highest psi I can run on a stock 5sfe. My engine has been rebuilt to an extent. Rings and a new crank as well as other tide bits. Would i need to build up my engine even for lower end psi numbers and if so what would i need to beef up?

What HP numbers would I be looking at if i run 5psi 8psi and so on?

The car would be a daily driver what would be a good boost and what would i get hp wise.

i have figured that with a N/A set up with CAI header and exhaust id be getting maybe 20 more hp so around 150. (CA stock is 130). I’ve been wondering if its worth the trouble to go turbo or if i should just stick with N/A.

thanks in advanced
