Can you put a supercharger from grand prix gtp on to gt?

No, you cannot directly put a supercharger from a Pontiac Grand Prix GTP (which used a supercharged 3800 Series II V6) onto a Pontiac Grand Prix GT (which used a naturally aspirated 3800 Series II V6). The engine mounts, intake manifold, accessory drive system, and other components are different and incompatible. A massive amount of custom fabrication and engineering would be required, making it a highly impractical and likely prohibitively expensive project.
