proper tuning is essential, amount of boost is dependant upon that first, then the strength of the internals. You can blow an engine on 3psi if it's not properly tuned. go on amazon.com or some place, and get a book on turbo charging.....you'll find out tons more information there than any honda board. And it'll be right. Most people on boards tend to repost things that they've read in magazines and on here, and believe me, a lot of the stuff is blatently wrong or simple guess work. Not saying that there isn't a lot of good stuff either - don't get me wrong. Seriously though, get a book, you won't regret it.
