The aftermarket is pretty big for the 3.8 . You can get a larger supercharger but there is also turbo kits out there. Take a look at these 2 sites I bet you'll see alot you like.

Yeah like the other guys said, it really depends if it'* a Series 1 or 2 L67 (3.8 */C). A series one would come from a 92-95 vehicle (in almost all cases, I think the Buick Park Ave retained it a bit longer, not sure), wheras a Series 2 would be from a 96+ vehicle. The Series 2 really has more aftermarket, and it'* a lot easier to swap to a better supercharger with the S2, as there are a few direct replacements.

PS I bet your Sunbird will go like snot once it'* done eh?
