Hi i have a stock 1994 sse and i was wondering if it would be possible to buy a new supercharger from GM, the same one that is on a ssei, and put it on my sse? If it is possible how much modding would be nessacery and would my engine and trans with 124k miles on it hold up ok? thank you this is my first post here.

Welcome to the Bonneville club. 1993 SLE is the guy to ask on this. It can be done, but will take some work. He should have the answers for you. Personally swapping out the engine and transmission is easier.
