What else do I need with STS full kit?
What kind of psi could I run with this kit on stock internals?
This kit is good for over 500 rwhp, right?
Start flaming me. I'm a newb.
and upgraded turbo. How much psi you want to run is just a matter of how risky you want to be. I usually try to get people to stop at 8 or 9psi on stock internals, but many people run much more.
