Top Cars

Techart has worked its magic, yet again, on the 997 Porsche 911 Turbo, boosting output of the twin-turbo'd flat-six to 660 hp and 634 lb.-ft. of torque. The Techart GTstreet R benefits from a duo of new turbos, larger carbon fiber inlet pipes, revised intercoolers and a new cat-back exhaust mated to the revised manifold which all help to drop the 997's 0-60 time to 3.4 seconds when equipped with an auto 'box and 3.5 seconds with a manual. Top speed is a claimed 214 mph.

Keeping the Techart-modified 911 planted at speed is a new coil-over kit and 20-inch wheels that work in conjunction with a wind-tunnel-tested body kit and carbon fiber spoiler to add another 22 pounds of down force. If those specs aren't enough to make it stand out, Techart also offers a new hood, carbon fiber headlights, side sills and air ducting for the rear bumper.
