The Type-R wasn't really built for forced induction...however, if I was going to go down that road, I think I'd go supercharger, just because it's a lot less maintenance than a turbo would be. not a bad system jackson racing has there either, I lost to a supercharged GS-R, but not until 3rd gear, and he had all the bolt ons and a semi-built engine while i was still stock...plus he lied and said he was just running bolt-ons...of course when you hear that whine...y'know that's BS...and when he tells you that he has a Jackson Racing Supercharger...it's just like, then why didnt' u say so in the first place! :evil:
