Techart releases new GT Street R package for the Porsche 911 Turbo

Techart is well known in the aftermarket tuner scene for creating some of the greatest performance kits for Porsche cars, so it comes as little surprise that there has been plenty of interest in the German tuner’s latest kit designed for the facelifted 911 range.

The GT Street R is fitted with a power upgrade kit, which boosts engine output to 660hp (485kW) and 634lb-ft (860Nm) of torque. These sees acceleration figures for the automatic 911 Turbo whittled down to just 3.4 seconds for the 0-100km/h sprint. The manual model takes just one tenth of a second more, and both models will reach a claimed top speed of 345km/h.

The increase in engine output is due to the addition of a pair of new turbochargers, large carbon fibre inlet pipes, special intercoolers, a sports exhaust system with high-performance manifolds, and an improved sports air filter.

Accompanying the list of engine mods is a new coil-over suspension set-up, a custom bonnet, carbon-fiber headlight and side mirror trim, sporty side sills, a carbon roof spoiler, and new air ducts behind the front bumper. The custom aerokit has been tested to add an additional 10kg of downforce on both the front and rear axles at speeds of about 140km/h.

At request, Techart can also add individually tailored leather fittings, 20in three-spoke forged alloy wheels and aluminum pedals.
