I had a brief chat to one of the guys at Ming Automotive (friend of a friend) who handle APS stuff in the ACT while at Summernats, and he mentioned the ultimate goal of a Phase 6 XR6T making roughly 1000HP. Naturally there would be bottom end mods and further drivetrain mods to cope with that kind of power. He didn't say much else but that would be a brutal car if they could pull it off. He is a Rex man, but loves the APS-kitted XR6Ts
