ok i have a 3.8 v6 series 2 swap in my car i was just wondering if anyone knows a website for either a supercharger or turbo for this and also wondering which should i go with

You can put a SC on your motor. Here'* some info on whats required https://www.gmforum.com/t279634/

the superchargers easier to do since theres one that came factory on this gen 3.8,
but turbos have been done before.
id go with a SC tho

the thing is though i know people have done turbos before but that is what i am leaning towards mainly for 1 cuz i love the sound of it haha i know that sounds childish but it just gives me chills down my spine. and also i know all in all a turbo may cost more but it is so worth it in my eyes but idk a website that carries a turbo for my car

check either zzp or intense, one of them has a turbo kit. you have to look under grand prix

zzp has a turbo that stattama made for them. And cartunning.com i think has another one with an intercooler comes to be around 5000 to 6000 dollars my SLE cost me 2.7k lmao So after I find every weak link in my sle and change and fix ima install a turbo as well im fixing her lil by lil i love her so much.

also look at 3800 performance they would give you a complete SUPERCHARGER kit or TURBO kit. they do an excelent job.

3800performance.com

also you need to know what your doing, even after you install it because there will be troubleshooting to be done
