Question type: Car Customization

I currently have a 3.8 v6 w/supercharge. Kind of wanting

put in?

don't.. it could bust the x-misson. if u can fit a northstar v-8 & x- mission. from a buick lucerne / caddy DTS only.


Pontiac put a V8 5.3 liter ls motor in the Grand Prix in 2006 It made 303 hp. Your supercharged 3.8 makes 240 HP. Swapping to the ls engine is a lot of work and wont be cheap. you would be better off making small upgrades to the 3.8. Thanks to the turbo buick crowd. There are lots of parts available for the 3.8. And lots of companies that offer parts specifically for the supercharged GP's
