Subject: [928] Forged components

There is a lot of confusion regarding forged components in the type 928.

The only "forged" pistons are in GTS.   All others are cast and in many
cases, have visible weaknesses.

Other than the gts, all rods are "sinter" forged, or powder metal technology
and not true forgings.

The only real forged rods are in a GTS.  The only good forged rods are the
ones in a 94 and later GTS, in all 92-93 gts's - porsche recommends that
they be changed any time the engine is dis-assembled for any reason...same
for a 968!

The cranks of the non GTS are all 6 counter weight and non-twisted forged.
The porsche stroker, the gts, is an 8 counterweight and forged.

The DEVEK stroker crank is a 8 counterweight and made (carved) from an
English billet forging.
