996 GT2 2001-05

The GT2, serving as the turbocharged counterpart to the GT3, opted for rear-wheel drive to save weight and minimize power losses through the transmission. This decision stemmed from the GT2's intended use in GT2 class racing, which imposed restrictions on all-wheel-drive systems. Equipped with a set of aerodynamic enhancements, the GT2 featured a re-engineered version of the 996 Turbo's 3.6-liter, twin-turbocharged engine. This iteration boasted larger turbochargers and intercoolers, along with a revised intake and exhaust system and reprogrammed engine control software. The result? A formidable 356kW (484PS; 477hp) at 5,700 rpm and 640 Nm (472lbf⋅ft) at 3,500 to 4,500 rpm, propelling the car from 0–97 km/h (0–60 mph) in a blistering 3.9 seconds and onward to a top speed of 315 km/h (196 mph). 

Standard features included larger wheels and tires, complemented by lightweight ceramic brakes. The GT2's fixed rear wing, constructed from CFRP in post-2003 models, was a nod to racing regulations typically banning adjustable aerodynamic components. For a stripped-down, race-ready feel, the GT2 omitted rear seats and air conditioning, instead offering a factory-installed roll cage. Like its GT3 counterpart, the GT2 was exclusively available with a 6-speed manual transmission.

Notably, the Turbo, GT2, and GT3 models retained the aluminum crankcase of the air-cooled 911, featuring a true dry sump oiling system. In this engine, each of the six individual Nikasil-lined cylinders is covered with two separately installed water jackets, providing water cooling to a crankcase initially designed for air-cooled cylinders. This contrasts with the standard 996 Carrera engine, where the cylinders and water jackets are cast together with the crankcase.
