Carpokes

Thank you for reminding these basics of engine design.
I don't see the point in building an oversized engine if we can't put the power to the ground, at least on a track car that is supposed to perform in lap times. If a destroked engine can make the same power, and that would be with the same peak torque as a stroked engine but at a higher rpm, then it should be more reliable and more responsive.
A well built engine should be able to run on full load without holding it back artificially with the tune.

You don't want to use stock S2/968 104mm pistons with a turbo, as turbo pistons are conical to allow for increased thermal expansion.

Of course, i was thinking of wossner who offer forged piston for S2 and 968 with 10.9 rv. Some of the retailler say there are meant for turbo application so i think i will go with that on my build
