You can just install the supercharger and call it a day, BUT to maximize power and reliability of the engine you would also need some way to get extra fuel whether it be bigger injectors or the URD 7th injector kit. With the extra fuel you need some way to help correct the ecu (AEM FIC, apexi SAFC, URD FTC, etc...) You would also want to have the transmission valve body upgraded eventually to handle the extra power. There's a lot more to doing it right with the supercharger then just slapping it on, but again it will run if you decided to just go that route.
