Hey all Im new to post in the forums, I been a MCF browser for a while. Well I was planning on doing a swap. I have a good deal on a 3.8L Series 3 supercharged with tranny on subframe coming out of 2006 Gran Prix. I herd about series 1 and 2 swaps needing only the wring harness, pcm, and if supercharged bcm. My ol' 3.4l has been rebuilt and i got a 260,000 out of it but its showin its age in my 2003 MC. Any info would b appreciated,
