Okay..I'm not picking on you, but there's more to this discussion that needs to be said.

h:
1) How can you say a blower is "better" for a certain kind of engine?
Regardless of engine size or layout, turbochargers produce a different kind of powerband than superchargers. It comes down to the preference of the driver. IMO, since our engines lack torque in general, I'd argue that a supercharger is more effective for a street-driven car than a bolt-on turbo kit, which does little to aid torque until around 3000 rpm.
2) Rebuilding Costs: Turbo vs JRSC:
Eaton, the company that makes the superchargers for Jackson Racing / Moss Motors can rebuild their superchargers just as easily as a turbo can be rebuilt. The difference in rebuilding costs are negligible, as Jackson Racing provides a 100K mile warranty on the supercharger. To the best of my knowledge, no turbo kit comes with that level of protection.
