Default 3.8L Supercharger

Alright, so I don't know much about forced induction so I'm gonna ask you guys before I buy a supercharger that I can't use. I found a couple auctions on eBay for some superchargers and got to thinking I would just put one in particularly one like this:
http://cgi.ebay.com/ebaymotors/Super...Q5fAccessories
I know they make the Grand Prix supercharged and its the same 3800 engine I believe. So my question is can't I just buy one of these and bolt it right up. I think the only question would be whether or not it has the same bolt pattern and whether the pulley will line up with the serpentine belt. Any input would be greatly appreciated.

I am just disappointed with my V6 and I can't afford a LS1 or an expensive turbo kit. Please tell me if Im missing anything or if there is a better bang for the buck. I just need some good cheap power, like we all do. Also anybody know how much power these things will produce, which one has the most power? Thanks

The fwd blower is not going to work without EXTENSIVE mods. Some people have done it though. www.fullthrottlev6.com, do a search.

The absolute cheapest and easiest v6 mod for big quick power is nitrous.

Cheapest constant FI solution for V6 is single turbo off front sweeping headers with a front mount IC. People have good success with that setup.

Blower is going to be a bear either way, but both styles will work, CSC being the easier of the two. To be honest though, if you sold the V6 now and added what you need to put together a kit that won't blow up your car, you can probably get an LS1 these days, now that the GenV is out. You are going to need fueling mods either way, a pump and possibly injectors, at the very least an FMU, but the FMU will not get you too far without a pump. Any of those will take custom fab work of some kind. You will need a welder, or a shop. I am not trying to discourage you, but if you bought that blower up top, and tried to bolt it up, you would be FUBAR.

The grand prix 3800 and your engine are two totaly different engines and would cost more money to fabricate/alter your engine than it would cost to do a ls swap or even a 3800 sc out of a grand prix

Well, that is actually not true. The block is the same. The heads will swap, but only if you use the corresponding intakes. The slugs and crank will swap, but the l67 slugs are of different composition than the l36 slugs. Blah blah blah. They changed it up just enough for FWD configuration to effectively make it easier and cheaper to do other things, that is the true part.

If it were that easy every V6 fbody would be running ~14s on a blower for under a thousand dollars. And what fun would that be?

V6 stock manifolds will not flip (same bolt pattern on both sides, not mirror), so if you use stock manifolds, you will have to either build a Y or put the turbo after the stock Y joins into one (around where the stock cat is), which is well downdraft of the cylinders and very low to the ground.

Seriously OP needs to search FI on ftv6 if he is serious about this.
