I've looked at those before on eBay. My feeling is that yes, they will physically bolt on, since the cylinder head ports and bolt pattern is the same. That's where it ends. You would have to make up a drive system to run the supercharger, you may just have enough room on the passenger side to do it, bu I haven't measured. Running the DBW throttle and the boost control / bypass valve will require an aftermarket ECU, such as Holley, Big Stuff3 or MS3. You would have to keep the original ECU to run all the diagnostics, transaxle, and body interface, but it can be done. Last problem I could think of would be hood clearance; I doubt it would fit without a "power bulge" on the hood. Again, I haven't measured, so I could be wrong. Transaxle would have to be upgraded, along with the CV axles.
So, Sempar, you don't think the stock trans and axles can handle the added torqe? I'm kind of curious to try this. I would definitely be willing to pick up an M122 blower from the bone yard and give it a go. I'm assuming I'm going to be needing the fuel rail and other little knick knacks lol
If you can find one in the boneyards, I'd break out a tape measure and measure all the clearances first, just to see if it can be fitted. I think the supercharger drive could be a real problem considering how little room there is already. As you mentioned "fuel rail and other little nick nacks " could make or break the deal, besides costing more money than it worth. I remember someone on this board a few years ago put a turbo on a 4.0 L Aurora, and found he had problems with the CV shafts and the trans. The trans can be built to handle the power, or more inportantly, the torque, but I have reservations about the CV joints and the half shaft splines that go into the trans. As tigger mentioned a STS V could be cheaper, but I'm not sure it would be as much fun!
