Well I just bought a Dinan Turbo E30 which runs up to 13psi just fine. It does have a bigger HG and some other things done to strenghten the motor's internals. You for sure would need a bigger headgasket and studs (400-500 for good stuff) and then I bet you could run 7-9psi on it just fine.

not needed at all. if under 10psi is the goal on a smaller turbo, just switch to the newer torx headbolts or some 12.9 bolts and you're fine as far as internals go.

if you want to pay for a kit, then go through tcd. if you want to build your own kit then do some research at e30tech. there's a turbo faq along with many many many threads about the subject, so searching should answer any possible question you may have.
