Has anyone took a regular 3800 and put a supercharger on it? And if so what all has to be switched out. I have a 94' Bonne SSE. I would like to supercharge it.

Yes . It'* been done. It'* not as easy as changing out the top end and calling it good. You have some wiring to do an PCM to change and some vacumn lines to re-route. If you search this forum you can find several posts on this subject as well as everything that you will need to make the top swap and other changes.

Take a look at this.
