After unveiling a styling upgrade for the 991 Porsche 911 Turbo at the start of the year, Techart has now detailed the tuning program for the 2014 Turbo and Turbo S models. Dubbed the TA 091/T1 power kit, the upgrade sees the 3.8-liter six-cylinder increase by 60 hp to 580 hp, while torque is upped to 620 lb-ft. The result is a 0-62 mph time of 2.9 seconds for the coupe and three seconds dead for the convertible. 0-124 mph is clocked in 9.8 seconds and the Turbo coupe tops out at 202 mph.

The kit also includes a special stainless-steel sports exhaust system with valve control. The Turbo S enjoys a boost to 620 hp and 650 lb-ft of torque, resulting in a 0-62 mph time of 2.8 seconds and a 203 mph top speed. To recap, the aggressive carbon composite body kit includes an active front spoiler, a fixed rear wing, roof spoiler, rear diffuser and aerodynamic side skirts. The German tuner also offers 20- and 21-inch alloys and sport springs.
