Exactly - the 997.1 C2 has a M96 engine (derived from the 996). The 997.1 C2S had an all new M97 engine. The 997.2 cars have all new DFI engines.

The 997.1 TT had a Mezger engine derived from the GT1 whereas the 997.2 TT (that can take a PDK transmission) is a DFI engine - essentially AFAIK the 997.2 TT engine is a twin-turbo version of the 997.2 C2S engine.

So, long story short, it's mainly a problem of engine compatibility with the PDK gearbox.

And like cdixon said, the 997.2 GT3 still has a Mezger GT1 based engine.
