I don't know of anyone making a supercharger kit for the four-banger, that means buying a centrifugal blower and fabricating everything else. Anything is possible, but there are a lot of easier ways to get power than that. Swapping in a small block chevy sounds like a big deal but as far as money is concerned it would probably come out about even and would take less time and ingenuity because it wouldn't require all the custom fabwork, let alone trying to make the computer get along with the blower. Good luck with whatever you decide.
