now has out an add-on supercharger kit for those of us with the SE and SSE, non-supercharged motors. I however would recommend against it for the exact reasons DeathRat mentioned. First off, the price they are charging for this kit is rediculas ($3,300+). For that price you could buy the complete engine / transmission / wiring harness / PCM'*, Etc... from a wrecked GTP or SSEi, and youd be getting ALOT more. Second, I dont think there is any way our transmissions (the 4T60E) like DeathRat said, will hold up to that kind of power and torque. With a complete swap you'd not only be getting the revised version of the 4T60E, the 4T65E, but also the supercharged cars 97 and newer came with a heavy-duty version designed to handle even more torque, hence the 4T65E-HD.
I've looked into the swapping idea in my '95 SSE as well, but to be honest, after a lot of research, I just dont think it would be worth it.. '96 was the first year for FULL OBD II, which means even though a 97 and newer L67 (supercharged 3800) will most likely bolt right into the same mounts in our cars, EVERYTHING else must be changed over, including the complete wiring harness, and computer. Your definetely looking at removing your dashboard completely like I did this past summer in order to swap everything.
Dont let me discourage you, because with enough confidence and $$ you can do pretty much anything, but for myself anyways, I have come to the decision of just finding a newer Bonneville that is an SSEi with the L67 motor already in it from the factory, or, maybe if I could find a complete L67, tranny, wiring, PCM, etc... basically a complete front clip for damn cheap like $1500 or something, I would consider the swap.
