yeah, ive been to the 60* V6 site and asked a few questions and got thouroughly flamed a while back. I know that there are a few sites that offer mods for the 3100 and 3400 engines such as milzymotorsports.com and wottech.com. But nothing along the line of superchargers, just P&P stuff and springs,cams,heads blah blah. But none of that stuff is cheap either, i think a lot of the heads and top/ bottom end swaps start at around $450 not including shipping....I believe i was told once that the old TGP 3100 was a completely different engine than the current L82 3100 V6...
