TRW forged pistons (340)

..lots of guys trash talk these heavy old school forged pistons (L2316-30)
..How much difference will lighter, newer style forged pistons or hypereutectics make?

Though the lighter Pistons will reduce the rotating-mass, that doesn't
necessarily mean more overall power.

But, yes the engine will rev quicker. And there will be less stress on the
internal engine components at high RPM's.
