Vortech Superchargers are already assembled on kit and are available from Farthing Racing. The kit contains the actual Supercharger (G or H trim), intercooler, mounting bracket, pulleys, belt, belt tensioner, etc. Whatever your needs are, recreational or racing Farthing Racing will give you the answer. However, Vortech Superchargers are still trying to get a deal with Kawasaki in order to use their programmable Mitsubishi ECU.
