Yau can't change the pulley type on the SC without changing all of the accessory ones as well to run the different belt, and they would have to be custom. IMO, all things being equal (horsepower goal wise) I would rather run a turbo at low boost than a JRSC because you can intercool as much as you want. The H22 can make alot of power with boost. after all, if you are going to spend the cash, why not leave room to grow by going with the turbo.
