hey guys, I have a 1994 sse(L27) but I want to make it supercharged (L67 94-95 225hp) and I need to know what parts I'll need for the swap.

I have been thinking if need to change the tranny fully or leave the axles?, so if the pcm just plug n play or have different connector? thanks for advices...

Well first of all you can't convert an L27 to a L67 series I without changing most of the internal parts like piston rods, bearings etc. For the tranny, well the L67 S1 came with the 4T60-E HD. And the one you have is the regular 4T60-E but i think you could use it with a L67 but i would put a better torque converter and a shift kit. Someone correct me if im wrong about the tranny. For the pcm and hardness you could use yours. Gmtuners.com could help you by updating your mem-cal/ chip of your pcm and that'* it. Search here L27 to L67 conversion series I buicks 1994. Im currently on a similar project doing the same thing want to do. But for you it would be easier. Oh and for the mounts and everything else you could just use the exact settings of the 1994 bonneville SSEi so again easier lol
