Porsche 911 GT3 new engine production starts April 22nd 2014

The new engines for the Porsche 911 GT3 (pictured) start production this month The recall for the Porsche 911 GT3 after a couple of fires forced Porsche to evaluate the cause – and stop further production – now looks to have not only been resolved, but a fix is soon to be available. But Porsche is taking no chances with any sort of sticking plaster fix and is instead building new engines for the 911 GT3, with optimized piston rod screw connection – the cause of the problem – to make sure nothing goes wrong again. Porsche are planning to start production of the revised engine on 22nd April and will be despatching engines out to dealers shortly thereafter for them to fit to the affected cars.
