Ok so I've read around about turbo'ing an xt. but how about supercharging one? what's needed to be done to put a supercharger in the xt? was the tailshaft changed? does it need to be? do I need a new trans? I have a 4sp also about the standard xt transmission, if I wanted to upgrade it to a 5sp or 6sp auto I think it's called a ZF trans? what would I need to do?
