Powertrain Options and Availability
Until 2001, the 911 came with a 3.4-liter horizontally opposed 6-cylinder engine that developed 296 or 300 horsepower. Turbo models got a 3.6-liter, rated at 415 hp. In 2002, the base engine grew to 3.6 liters and 320 hp, and the new GT2 got a 456-hp version. A 6-speed manual transmission was standard, with 5-speed automatic optional on regular 911s--and starting in 2001, also on the Turbo. For '03 Porsche offered optional "Horsepower Kits" that boosted the base engine to 345 hp and the turbo to 450 hp. Turbos retun in the middle of 2006 as '07s with 480 horsepower.
