Techart Adds 660 HP GTstreetR To Porsche 911 Tuner StableSTuner Techart, apparently inspired by Porsche's endless 911 iteration game, has released its GTstreetR version of the 911 Turbo. The new model slots between the company's 630 HP GTstreet and 700 HP GTstreetRS, producing...you guessed it: 660 HP. The mods read like a laundry list of Teutonic speed parts, including new twin turbos, custom exhaust, special intercoolers and a custom coil-over suspension setup, all dressed up with scoopy bodywork said to add downforce. Of course, with stats like 3.4 seconds to 62 and a top speed of 215 MPH, who are we to be skeptics?
