TRY OUT ZZP performance.com. 3800 performace.com grandprix.net, Wbody performance.com, SLP(look under Wbody)Summit has alot of parts also but nothing like The 1st few sites i put down. I believe the SSEI, GTP, impala SS, MONTE CARLO SS, N sum others should all have the same EATON M90 on there. Not sure but i would look for 97-03 After that is the series 3 SC i believe. Who told you it needs a new supercharger?? if it still runs and drives might just need couplers. IF it sounds really bad from the NOSE of the SC,then you could just need a rebuild kit from ZZP. TIP!!!!! If your tranny is still working, GET A HD SHIFT KIT (80 bucks) and tranny cooler cuz i had to pay 1300 for a rebuild !!now its drives way better and the shift kit is great
i would say buy these, the OIL IS A MUST! and YOU GOT TO BUY 2 bottles 1 isn't enough. I think intese racing has the bigger (1) bottle unit but its all the same. I GO with the GM bottle(s)

NOw you could just need to top off your oil, its a little hex on the nose of the SC. DO NOT STRIP IT!!!!!!!!! buy some GM SC OIL(autozone, napa don't carry it you have to order it) get that and top off. THo not to waste the oil i would just buy the couplers and oil. I'm at about 250k on my GS only had to change couplers and oil(at about 170k). Tranny gave out just a few weeks ago.
So unless your friend rags his car out everyday, then im sure its a 50-100(parts & Shipping) Fix and 2hrs of work or under.
