well i dont know how much truth this holds, but i was told that a person put a reverse scroll set up on a 1g, but wasn't a direct bolt on. he had to move the air compresso0r and put the alternator there. this person also didn't have power steering and all of the other creature comforts. i was told by jerry that the persons set up put down alot of efficient power, but it wasn't worth the time and hassle. i think that you guys are arguing whether a reverse scroll will work on a dsm car, and the answer imo is yes, with a shit load of time and no a/c it can be done.
