After running into countless problems with the over-tuned, naturally-aspirated 3.8 liter flat-six they used in the 991 GT3, Porsche seems to have learned its lesson and is reportedly going to turbocharge that engine for the next GT3 RS. Their main concern is to improve the reliability of the engine.
The naturally-aspirated 3.8 engine in the new GT3 is tuned, literally, to destruction. A large number of them spontaneously combusted a few days after delivery, forcing Porsche to get them off the owners’ hands and replace the engines. A lot of them have not yet made it back from the recall.
So for the next Porsche 991 GT3 RS they are thinking about achieving the performance they need through the medium of turbocharging. This ensures the engine is capable of punching enough horsepower to earn its RS badge while remaining safe and reliable. The thing is, it brings the GT3 RS into the GT2 territory, rendering one of these models entirely pointless.
In other radical developments, Porsche is said to be considering the GT3’s rear-steering system for the Cayman. The sports car may also get a new four-cylinder engine boosted with electricity to make 400bhp.
