1. maybe this should go in the turbo section.
anyway, if you want a greedy in your altima, i think theres going to have to be some major modification. pretty sure greedy dosen't make turbos for 93 altimas. also, is it really worth it? i can see this costing you well into the 3000 or 5000 dollar range. i dunno, i'm not the turbo guy, so you'll have to talk to them.
