There have only been 3 generations in the last 15 years and it hasn't pioneered anything with F.I. lately. The Turbo bore the first variable turbochargers, not the GT2. It's a mere child compared to the Turbo in terms of what it's done for Porsche. Plus some say the Turbo WAS the old GT2, just now with AWD as standard.Originally Posted by matthewAPM
