    • Porsche 992 GT3 to utilize 991.2 GT3 4.0 liter flat-6?

      It seems a bit odd for a new Porsche GT3 model to utilize the same engine as a predecessor but it seems what is likely here is that the same architecture will be used. The 992 GT3 is expected to stay at 4.0 liters of displacement.


      That does not mean the motor will be the exact same. A lot is being read into these comments by Porsche GT head Andreas Preuninger:

      Our philosophy in GT cars is to stay naturally aspirated. We want to keep that engine for the future and that’s why we’ve made such a tremendous effort to get the engine right without taking emotion and performance away.
      Essentially he confirms the next GT3 will be naturally aspirated and says the engine will be re-used but that should not be read as the GT3 will have the exact same motor.

      Remember, Porsche talked about going to 9500 rpm for the GT3.

      Porsche can also likely stretch the motor to 4.2 liters but it seems the 992 generation GT3's will start at 4.0.

        GT cars to stay naturally aspirated is not accurate either, there’s always been the GT2...

        From what I read the GT3 engine cannot really be taken further, even the GT3 RS was not discernibly more powerful than the normal GT3 and even on dynos there was almost no difference. But I agree it would be a pity to dump that marvelous engine.

        They will go with a more aggressive tuner speedster engine which is based on the 4.0 991.2 GT3/RS engine

        changes are

        6 individual thrttle bodies
        GPF in the exhaust (mandatory now) but as a benefit lighter exhaust since side mufflers are no longer needed.

        Yeah I think he clearly meant GT3 in that context though.
