FYI: You can go on ebay and get a rebuilt eaton m62(the one used in the Alpine kit) supercharger with a upgrades and a decent warranty for less than half the cost of that one. You also still need to get the bracketing, pulleys, intake manifold/injector portion, etc in order to make it all work. Unless you are a handy guy and have time to tinker on your hands and don't mind your VX being down for awhile to install and test, I'd stick with the alpine kit. If you do have all that stuff, then good luck and don't forget to do a writeup for the rest of us poor schmucks who cant afford the kit .
the price is in NZ $.... half the price would be about .... $300 us....
