I'm sure this has been asked before, but I couldn't find a definitive answer. So here it goes:
There's an auction up my way this weekend. I was looking through the listings, and theres a 2003 Buick Park Avenue with 400000 kms (250000 miles approx). It has two sets of tires on rims, so if it goes cheap, I want to buy it just so I have some rubber and rims for the winter. Now, this one has the supercharged 3.8 in it, and I was wondering, is it any way possible to put this on a 4.0 Aurora? Thanks in advance.

I don't know for sure, but I don't see how.. For one, the 3.8 is a V6 and the 4.0 is a V8. Plus, the 3.8 is a normal head/valve/cam setup, and the 40 is DOHC and the upper/lower intake are totally different..
Would be interested in seeing if a SC or TC could be retrofitted, though!

For the 3.5, yes. Lots of fabrication, but yes. (GM did it on the Intrigue OSV)
For the 4.0, NO.
You'd have to completely fabricate a manifold, and relocate the starter.
You'd also have to figure out how to get a belt to the pulley that would have to be added to the front of an accessory area that is already EXTREAMLY close quarters to begin with.
Now that the problems installing are out of the way, the supercharger would be too small as well. With relatively minor modifications, the stock M90 supercharges run out of "huff" well under the 6K RPM range on the 3800.
The 4.0 is larger, higher RPM, and more horsepower in its stock form. My guess would be **IF** you figured out how to install it, it would be a benefit on the bottom end, but would be a limiting factor on the top end.
I have a feeling that these are a few (of many more I'm sure) of the reasons they did not supercharge the Northstar until it was installed in a RWD platform in '06 (Cadillac STS). None of the parts from the RWD version will retro-fit to the FWD versions.
Based on the amount of space we have to work with on these cars, I really think the remote turbo set-up (goes in place of a muffler) would be the only way to add some "un-natural aspiration" to our cars.

If you buy it, measure the rear rotor diameter. If it's 11.7", you need to keep them for your Aurora.
I think it may have been the later years ('06+), but it's worth checking before it's scrapped.
Whenever they made the change, the "Ultra" package also included the larger rear brakes (same as the Bonneville GXP in '04-'05 except with black calipers instead of red).

You would have to rebuild the engine and lower the compression..

Thanks guys for the input, had to work on Saturday so I didn't get a chance to go. Asked my dad to go for me and bid on it, but he never did. Went for $400. Guess I should have taken the day off.
