    I just bought a 2002 Pontiac grand prix GT 40th and I realized the only difference between the GT and GTP is the supercharger kit. Has anyone installed one of those superchargers from the GTP on an N/A 3.8L GT and transferred the components? If not does anyone think this is doable and what needs to happen?

    Been done a lot. Called a "top swap". There should be plenty of info on here and I'm pretty sure a how-to on what needs to make it all work properly.

    Wouldn't say the "only" difference.


    The L36 has a different compression ratio than a L67. Difference cylinder heads and top end parts. The transmissions have different gearing and the supercharged cars come with a "HD" differential.
