    3.8l swap

    Im wanting to do a manual swap on my 99 grand am and put a 3.8 supercharge in it but im not sure what manual transmission bolts straight to it. Any help?

    Heard about some 6-speed swaps from a later model G6 but nothing I'm aware of that is proven. If you're just looking for a supercharger there were at least 2 kits for the 3400 that I've seen, and that direction is going to be easier than putting in a different motor and trans.

    Also the Getrag F23 5-speed from a 00-02 F-body bolts up and is a stout transmission. It would have also come in 00+ 4-banger grand ams.
