Due to 911 GT3 engine reliability issues

A new report indicates Porsche is taking into consideration using a turbocharged engine for the upcoming 911 GT3 RS.

It is believed engineers at Porsche are worried about the reliability of the flat-six 3.8-liter engine installed in the plagued 911 GT3 which is why they are analyzing the prospects of mounting a turbocharged engine to squeeze the extra power the "RS" badge imposes.

This rumor makes sense taking into consideration Porsche CEO Matthias Müller said earlier this year the model could be delayed as a result of the fire-related call of the 911 GT3. However, adopting a turbocharged engine for the RS version could upset purists who prefer a naturally-aspirated motor.

In related news, the 911 GT3's four-wheel steering system will reportedly be offered on the Cayman, possibly for the range-topping GT4 version.

Then what prevents them from calling it GT2 RS?

First no manual transmissions, engines catching fire, and now possibly a turbo charger for the GT3. Stop digging Porsche! You are already deep in a hole!

Just bring back the 4.0 engine of the latest 997 GT3RS 4.0. It makes 500hp, good torque, and sounds fantastic.

Turbocharged GT3 means GT2, no?

I am guessing here, but I suspect consolidating the GT2/GT3 and RS concepts is simply due to engineering resources: these great cars take a long time to develop and involve a lot of very smart people innovating and perfecting...and simply put, there is more money in doing that for a new sub-Boxster/Cayman car, or a new 928, which will sell in the tens of thousands per annum, rather than a few hundred.

sounds BS to me, it wouldn't make it as a GT3 RS if its not a naturally aspirated engine.

Nonsense! Keep it N/A! I don't belive that Porsche enginiers had problem with design N/A engine! Look at ferrari or even honda! There was close to twenty years ago engines with even 120HP per litre in series production without problems with broking connection rods! If there is real problem so why they keep with 3.8 displacement? Make it 4.0 or even 4.2 in GT3RS but with lower revs. But not turbocharged!

A naturally aspired engine is fun with a manual box. Since the GT3 now comes with PDK only, it doesn't matter if the engine is NA or turbo charged. Also, since they don't plan a GT2 or a hardocre 911 turbo, they might as well make a turbo GT3 RS.

Trust me, it does matter! Many of user of GT3 and especially GT3 RS using it on track! There is huge difference - N/A is better, some compromise is supercharger. Ofcourse PDK or sequencial gearbox make difference smaller but you still have to carry about nonlinear power. Forgot for one moment about it when you take out of the turn and you lost control. You can habit with this but people who buy GT3/RS instead turbo or GT2 don't want it.

Yes indeed disgraceful but and this is a big but, if Porsche had torque -fill like the 918 spyder there may be no need for a GT2RS anymore. Current GT3 owners had to swallow the PDK and 4-wheel-steer. A sign of them times i guess.

No, a sign of blatant greed so they could save the $$ from developping a manual version, just like abusing CPU's in order to save more $$ instead of using the Metzger motor. The latest M3/M4 is turbocharged and offers a manual stick.
