We’ve already seen the facelifted 2009 Porsche 911 Carrera 4 and 4S as well as the 911 Tara 4 and 4S. Still to come are the facelifted versions of the 911 Turbo, 911 GT2 and 911 GT3 – but who’s really looking forward to that since Porsche’s design changes aren’t that apparent to the naked eye. However, it’s the mechanical changes where the 2009 911 models shine.

According to AutoCar, the 2009 911 Turbo, GT2 and GT3 will all get direct injection gasoline engines as a par of Porsche’s new plan to increase performance and fuel-efficiency of its cars. All will drop the 6-cylinder M97 powerplant for the new A91 Direct Fuel Injection engines first seen in the 2009 911 Carrera.

The 2009 911 Turbo and 911 GT2 will get a new 3.6 liter A91 with direct-injection and twin-turbochargers and intercoolers. Sources say that will give each model a bump of 20 horses for a total of 500-hp for the 911 Turbo and 550-hp for the 911 GT2.

The 2009 911 GT3 will be powered by a naturally-aspirated 3.8 liter A91 with a couple of other upgrades to the engine that will give it a total of 430-hp.
