What are the differences b/w the GT2 and the 996TT X50?
Transmission?
Turbos?
Suspension?
Weight?
Etc....
I know AWD.

Thanks,
Tim

GT2 has lower weight and 2 seats. X50 has four seats (albeit the back are small).

X50 has PSM, GT2 doesn't.

They both use the same size turbos (K24s) and intercoolers. I think that that GT2 runs 0.1 bar (?) more than the X50 package setup on the ECU, maybe more. I am not aware if there are any cam setup differences or any other engine differences. Can someone confirm?

The motors are identical. In general GT2's should run about .1-.2 bar more. But from some of the info some X50 owners have posted it doesn't appear to be true

are you talking about just engine? otherwise there are many differences.

The motors are identical (including the GT3 oil pump not found in the TT motor). The turbos and intercoolers are also the same. The GT2 has slightly more boost (.1 bar). The GT2 has a very different suspension (many different components), RWD (rather than AWD), no PSM, and no back seats.

No sunroof in the GT2, minimal insulation and $50k more.

lots of differences. my list is at the office, but from memory: different suspension, pccb, trans cooler, vent at hood, tail, front spoiler, different syncros, ride height, muffler, lighter, smaller gas tank, no back seat, less sound deadning, no psm, headliner, wheels...

GT2 has a GT2 badge on the back and the turbo doesn't. Clearly, the obvious reason to buy one.

What is PSM?

stability control.

the answer is not one you cannot descirbe without taking you for a drive.

PSM is Porsche Stablility Management AKA PSM=PLEASE SAVE ME.
