Wife has an 03 gt auto. Has stage 2 high tech stage 2 cams, and usual engine bolt ons, 4.10's, edge 3000 converter. She wants a supercharger now, but still drives it on the street quite a bit. So far it looks as the best ones to consider would be the v3 si trim intercooled vortech or the intercooled p1sc? Which one do you guys think would be better? Where is the best place to buy a COMPLETE kit from?
