93 mustang hatch SUPERCHARGER????

Well, the problem is that nobody makes a supercharger kit for the 2.3, at least not that I know of. If you wanted to put one on there, it would require extensive fabrication on your part just to make it work. And then, you wouldn't be able to run more than...what is it, 10 psi? or is it lower than that? I can't remember. Which, with a supercharger, would give you a negligible gain for the time & money spent. Now there's a chance somebody does make a kit for a 2.3L, but if so it will be designed to fit a late model Ranger and will cost around $3000 like all supercharger kits.

The only way to get any real power is to swap in a turbo engine. You can pick one up for less than $500.

I have been curious about a blower myself on a 2.3, and if I can get a huffer for a decent price I may play around with the idea but as mentioned above a turbo is easy and readily available and easily upgradeable.
