Default 93 Bonneville NA to */C

Alright so i'm new to 3800 engines and have a little project i was wanting to do. I have a 93 Bonneville 3800 na that i was wanting to supercharge. What all will i need? Just the manifold and blower, and the supporting pulleys to run the belt? Already planning to put a custom exhaust and get a tune for it, just not sure what all i'll need to put the actual blower on.

P.*. its my first 3800 because i got the car for $100 bucks from work and my friend and i have some crazy ideas for this thing. I'll keep you guys posted on Project $100 Bonneville.

Chris

Dan'* link is good, although it doesn't fully answer all your questions. Being a 93, your heads etc should be the same as the SC'd of your year. Whereas in the L36 they are different with different compression.

Toughest part should be the tune and it sounds like you have that covered.

Thanks guys. Yea, i forgot to mention that i work at a shop building racecars and drive a modified 96 camaro ss myself. So i have a good deal of experience with this stuff, just my first journey into a 3800 v6. Can't wait to see what this thing can do. Videos and pics will be posted along the way as my buddy has a crazy camera

L26 was one of the newer versions of the 3800, called the Series 3.
