Hey, you've got quite a project! If you leave on the supercharger and injectors from the 92 engine, everything will work just fine given that it'* hooked up correctly. If you use the newer supercharger, the one that 94-95 SSEis had, you will need to get a new tune put on your PCM. You need to contact Sinister Performance if you'd like to use the bigger supercharger.

The question of Series 1 to Series 2 part interchangeability was brought up. The article for installing a supercharger on an NA engine doesn't cover the Series 1 because it'* so different. It doesn't use OBD 2 with which we're familiar, and most of the engine shapes and sizes are different. Look for turbocharged400sbc on this forum and on 3800pro.com to see the Series 1/2 hybrid that was started. They tried putting Series 2 heads on a Series 1 block, but that'* where they stopped. You need a custom LIM because the heads are so different in design. Pretty much nothing swaps over directly, but with plenty of cutting and welding I guess anything is possible.
You have a really cool project. I suggest for simplicity'* sake that you stay with the 92 supercharger, but you can go to the 94-95 version with the bigger throttle body if Darth Fiero can burn the proper tune for you. Tuning a Series 1 is much different from a Series 2 because the OBD 1 system needs to have a chip burned with new info as opposed to the Series 2 simply getting a new tune via the OBD 2 port. It'* only difficult in that you need to get a tune burned to a chip, but I guess nothing should be hard for you with all the awesome work you've done so hard. Once you jump that hurdle, you should be set tuning-wise and ready to start the engine.
