i believe u have the wrong idea about superchargers and turbos. first thing a turbo does not just provide short power gain. as schmoo said a properly sized turbo for your goals can allow for hp increase across the entire powerband. a supercharger also has the same quality but with a supercharger u are already using up some of your excess power gains just to drive that supercharger as they are a belt drive system. also future upgrade options with a supercharger are near existent whereas a turbo setup allows for almost endless upgrade options. i would say go with a basic turbo kit such as the greddy and start with that.
