actually, just about everything is available, sans turbo, superchargers, cams, exhaust, intakes, pulleys, ecu's suspension mods, wheels, just about everything someone could want, its just that they are expensive. cheapest supercharger is a 6.5 kleeman, 8k with intercooler and higher boost, and a few others. nobody has done it yet, no one has bought cams yet, no one has bought the pulley kit yet, and we have only had one dyno, and that was before the ecu mod, the guy who was supposed to show the "after dyno" of the ecu seemed to disappear, as most people do. so yeah, thats crossfireforum.org in a nutshell. if you want to know about mods that have been done, ask hddp.
