Wouldn't a turbo create more underhood heat? What about all the extra plumbing for the header exhaust, and you still have to fab up an intake. Oh yeah don't forget about turbo lag too. Seems to me a two speed centrifugal S/C is the way to go. Also don't have to worry about cooking the oil in the turbo housing. Each system has it's benefits and drawbacks, but I do like S/C more myself.
