Porsche 911 Turbo, Porsche 911 GT2, Porsche 911 GT3: All with direct injection!

Porsche 911
It’s official: also the high-performance models from Porsche like the Porsche 911 Turbo, Porsche 911 GT2 and even the Porsche 911 GT3 will feature the new direct injection petrol engines.

Both the 911 Turbo and 911 GT2 are will get the new 3.6-litre version of the horizontally-opposed, six-cylinder A91, with a 97.0mm bore and 81.5mm stroke (compared with the old engine’s 100mm x 76.4mm). This ultra-modern direct injection unit also gets twin turbochargers and intercoolers.

Official power figures are yet to be revealed, but Autocar sources suggest a 20bhp increase over the old cars, taking the four-wheel drive 911 Turbo up to 500bhp and the rear-wheel drive 911 GT2 to around 550bhp.

The updated rear-wheel drive 911 GT3 will get a naturally-aspirated 3.8-litre version of the A91 engine with 102mm bore and 77.5mm stroke. It will receive a number of internal revisions over the engine used in the 911 Carrera S, including lightweight pistons. This should push power from today’s 415bhp to nearer 430bhp.
