Written by tonks on July 30, 2008

Porsche 911 TurboPorsche will be using the brand new direct-injected A91 flat six in the 911 Turbo, GT2, and GT3 models. The two turbocharged 911’s will have 3.6 liters of displacement with a 97mm bore and an 81.5 mm stroke. They will also have intercoolers and revised turbochargers.

Sources suggest that output on both models will rise by around 20 hp, with the Turbo producing 500 hp and the GT2 pushing out approximately 550 hp. Torque figures should also increase by around four percent.

The GT3 will stick with the naturally aspirated 3.8-liter version of the A91 with a 102 mm bore and a 77.5 mm stroke. The same internal changes from the Carrera S will carry over to the GT3, including lightweight pistons, valves and springs. Output should increase from around 415 to 430 hp. And all of these changes will also increase fuel efficiency and decrease C02 output.
