Will a Procharger P600B, 2 core intercooler that came off a 97GT work on a 02GT? I ran across a guy that had one on his 97 GT. He totaled his car from the side and back and has had the thing in storage for a year. He is asking 1,900 for it. It's still under the warrenty.
I think you would need a new mounting bracket, not sure about anything else, but I would think it can be done for a minimal cost, sure cheaper than buying a new one.
A different mounting bracket and idler pullies. The front cover was different from 96-99(early 2000), had different tensioner, belt routing, and idlers. Call procharger and see if they make a bracket for a the 600 for the 02 front cover before you buy the blower.
