Exclamation Grand Prix GT to GTP conversion??

I have a 99 Pontiac Grand Prix, it has the 3800 engine in it, and i'm looking to supercharge it with stock GTP supercharger. What other parts would i need to supercharge it besides the supercharger? Are the injectors the same size? What about the ECU/ECM would i need another one, like the one out of the GTP? Any help is appreciated! Thanks!

Re: Grand Prix GT to GTP conversion??

It would be better just to purchase a supercharged engine from a wrecking yard since trying to supercharge the standard 3.8 could lead to some real problems. Secondly, you will need a PCM, ECM and a host of other items to make this work in your car. One of the most important items will be a new fuel pump that will give you enough fuel when the supercharger produces boost. This would be the least labor intensive and most economical way to do this conversion.
