LS9 Supercharger
the pulley as long as its 6 rib, is no prob for me. acc. easy to modify for correct spacing
I think there is a thread floating around with part numbers for the blower and the intercooler. I checked them on GM parts direct a couple months back and I think both parts (total less shipping) were around $3,600... now that I think about it, that might have been for the Cadillac LSA blower and intercooler... I really don't remember.
I am guessing you would next need to get the LS9 crank pulley because it has a separate belt for the supercharger. I am pretty sure the LSA runs with 3 belts - one for the blower, one for the accessories, and one for the A/C. I think the LS9 did some weird stuff where the blower belt also ran the alternator or steering pump or something? I think the LS9 also runs an 8 rib belt on the blower, as opposed to the 6 rib on the Cadillac.
I also hopes someone does one of these swaps, too. If I ever actually get my car running (progress is soooo slow when you're always out of town) I am going to buy an LSA blower and intercooler (my buddy works for Eaton) and find a way to make it work.
From everything I have seen so far, it looks like it will be easier and cheaper to integrate the LSA blower than it will the LS9 blower.

My goal would be to fit the blower/intercooler to an LS1-LS6 based engine.
The first issue would be the actual fitment of the blower to the heads. The LS3 heads have a different port shape and I think a different bolt pattern (where the intake manifold bolts onto the head) than the LS1 heads.
The first order of business: someone needs to make a spacer plate that goes between the blower assembly and the head. The plate has to act as an interface adapter between the blower and the heads.
Maybe it's easier than that - maybe you can tap holes in the LS1 heads that line up with the holes on the blower? If there's enough material left in the right places, it would be a simpler and more straightforward approach. The only thing you would have to deal with would be the different port shapes. If the LS3-LS9 is as tall as the LS1-LS6 port, you could probably get away with porting the LS1-LS6 heads to fit the larger ports on the blower.
Third option - and it's a long shot - drill new holes in the blower that line up with the holes in the LS1-LS6 heads.

it would be easier and wise to just use rec. port heads, since the lsa and ls9 were designed around the ports. direct bolt on.
I don't think the LS3 style heads will work on an LS1 engine, will they? I think the LS1 bore is too small.
oe rectangle port heads, l92/ls3/l76, will not work on any bore smaller than 4.00
there is said to exist some "small bore" l92 heads. but i think the AFR, TFS, and other abc heads have got them covered anyway. cfm, deck thickness and other desirable features.
love turbos, but there is something about that roots blower whine that is intoxicating. So if you can't use LS3/L92/LS9 heads, your only option is to stick with the LS1-LS6 heads and adapt the blower to those heads.
Maybe I will throw down the cash for a new blower in a couple months. That way, we can see exactly what will work and what will not work. I still think the best options to fit the LS9 or LSA blower on the engine would be:
1) Drill the blower to match the LS1 heads; port the heads to match the blower; uses LS9/LSA blower gasket
2) Drill and tap the heads to match the blower; port the heads; uses LS9/LSA blower gasket
3) Make an adapter plate that interfaces between the LS9/LSA blower and the LS1 heads; the plate can be ported to match the different port designs; it will use an LS9/LSA blower gasket and ??? for the LS1 heads?
Please comment on any/all of the 3 options!

Well after doing some research on the ls9 supercharger, It will cost u 5213.66 for all the parts for the thing. Not bad , maggie is around 6500.00 and u cant make the power that u could make 2300
