370Z Supercharger or Twin Turbo

JARblue

If you have a chance, I might recommend test driving both supercharged and turbo vehicles. You can probably do this for free at various dealerships. Obviously, the cars won't be the same as the Z, but you will get an idea of the driving differences in each system. For example, you've never driven a turbo, so there is a possibility turbo lag will turn you off immediately and completely (there are plenty of people like this - but I think they are generally just spoiled from the instant boost a supercharger provides). From your post, I would lean towards the supercharger
