I would upgrade the 996tt. There is a lot of performance upgrades for the 996tt out there. You could add a pair of GT2 turbos and intercoolers, the possiblities are unlimited. My personal favorite upgrade is the autothority stage 5 ecu upgrade. Sure it costs 20k+ but you cant beat the 355 extra horsepower you gain( total HP= 770). Thats a deal compared to buying a brand new GT2 for 200k.
Alot of these performance parts can be bought here at pelicanparts, also performance products and lindsey racing
