Thanks for the replies... so the GT2 takes the strengths of the GT3 engine and furthers it with the turbo from the 997 Turbo? Or is it a different turbo itself designed more for racing?

Not trying to be looney about it, but the myriad configurations for the 997 are dizzying. I have a 997 S and am quite content with it for now, but I'm looking to the future...

I had the chance to drive a GT3 and the experience was amazing... the engine/exhaust sounded much more brutal, and so did the ride feel: brutal. Cant wait to try the Turbo out. GT2 might be out of my price range for some time, but I am still daydreaming.
