I have the os giken twin and the upgraded slave. Built 3.8 hr GTM TT making 700whp 700wtq . took it to the track and it held fine on a 10.60 pass and daily abuse.

 

def. need the upgraded slave . Mine stock slave only lasted a few hundred miles with the twin disk.

 

the OS is a very popular setup for the HR

if you need one, let us know

 

Thanks guys, I have the OS Giken coming in and should have it tomorrow along with the CSC. Hey neverenough I have an off topic question for you, what kind of fuel system setup are you running. The very last thing I need to complete my setup is a good furl return/ pump setup. Trying to stay in the budget yet gotta pay to play so need something quality. What did you do? Anybody else have a say? It is so hard to find compatible and readily available parts for the HR. thanks for everyone"s help.

 

did the gtm stage 0 return with mine with a sard regulator

 

Its the twin in tank kit. GTM put it all together with their fuel rails and regulator.

 

Ok Thanks. I'll see what I come up with.

 

Flywheels are different. The HR flywheel and clutch is the same as the 370z. The DE flywheel has a different shaped timing ring and it's in a different location then the HR/370z.
The clutch in the 2005.5-up HR/370z is 240mm and the DE 2003-2004 used a non self-adjusting 250mm pressure plate. 2005-2005.5 used a self-adjusting 250mm pressure plate made by LUK. This occasionally varied, but generally is true. Also, the HR/370z pressure plate uses a rounded diaphragm finger for the CSC where both DE style pressure plates had flat fingers for the rounded DE bearing.
