I can't seem to find any sites that off them. I know they must have them. Does anyone know of any sites that offer supercharger or turbo kits.

Thanks

The only supercharger for the 2.8 and 3.1l cavaliers is made by these guys.. and it's expensive as crap!!

For a turbo setup your only option(easy option that is) is to find a 1989-1990 TURBO GRAND PRIX, and swap motors. The swap is fairly straightforward, and can be done by most any able bodied backyard mechanic. You can usually pickup the motor/turbo/computer/and everything else you need from a junkyard for around $800, rebuild the motor $400, and have yourself a turbo cavalier!! :smoka: For more info on the swap check out Curtis Walkers website. He was one of the first guys to do the swap, and after lots of work I think he's running mid 13's at the track!! :eek:
