I am assembling a clutch kit for my 02 Turbo with Markski 850 turbos, all supporting mods making somewhere between high 5's and low 6's at the wheel.

My questions is if the 764PP and the GT3 RS 4.0 disk and associated TO bearing will work with the factory dual mass flywheel. I would prefer to have the dual mass and not use the 964 RS unit.

I'm working off a parts list from @pwderhound built for a conversion (including the factory 964 RS lightweight flywheel) below.

Sachs 764 clutch pressure plate (88.3082.999.764)
997GT3RS 4.0 clutch disc (997.116.013.91)
964 LWFW (964.102.239.31)
Flywheel bolts 9x (928.102.151.01)
Pilot bearing (931.102.111.00)
Throwout bearing (944.116.080.01)
Guide tube (950.116.813.30)
Guide tube bolts 2x (999,270.070.01)
Ring gear (964.114.143.31)
Pressure plate bolts 9x(999.510.015.02)

 

The only parts to be cautious about between the RS parts with regards to the flywheel are the TO bearing guide tube and disk. The RS LWFW disk is designed so that the sprung hub fits in the recess of the LWFW. If you try to flip the clutch disk 180deg then it will hit the pressure plate. Because the dual mass flywheel does not have the center recess dished out there is nowhere for the clutch disk sprung hub to go. You would be better off with a solid center GT3 street or turbo type disk. No need for sprung hub on a DMFW. So the GT3 street solid one would work just fine. Also, look into the Sachs high performance disk for the turbos. These supposedly have better friction material.

 

Here is a picture showing the LWFW dished center and a DMFW for comparison.

 

VAGscum, thanks for the detailed explanation and pics posted. Good info.
