correct if I'm wrong but a doesn't a turbo set up cause a bit more heating of the air as compared to a centrifugal compressor? so it will probably require a larger intercooler and higher octane fuel, right? I don't know turbo's sound like a bit more work and may not be as durable as S/C.
sounds like it more work to fab in a turbo too, thus more money needs to be spent on accessories and what not.
