I got a pretty good deal for a ORC 709 twin plate clutch for 600 bucks didnt wanna let it pass, set my engine back a few weeks but the good old bike gets me from point a to b. The problem is now that i look at it, it doesnt look like it,ll mount to the 2 1/8 nut it actually mounts to a 6 bolt pattern. it will be a turbo 2 s4 engine and ive seen stock turbo flywheels and it looks like it also uses the 2 1/8 inch monster. Ive also seen aftermarkets that look like they use the 6 bolt pattern but look like they can also use the 2 1/8 inch whereas my ORC 709 doesnt look like itll take the monster nut. Does anyone have expeirence with this clutch ive searched and couldnt find anything. thanks guys...

 

all wankels that I've ever seen use the monster boltt.

S4 and S5 TII's definatly don't.

Why don't you look up the numbers on the clutch to see what it's for

 

well the funny thing about that.. when i searched it told me that a s13-s14 240 non sr20(funny my brothers really hoping it wont bolt us so he can steal it) can use the bolt pattern and a r32 and r34 gtr skyline has the same bolt pattern also a fc3s and fd3s. i was under the impression that fc3s was the chassis cold its deffinetly a possiblity im wrong but that what i thought. Maybe i need an adapter plate? Thanks for any help again..

 

Ive heard you could use the automatic counterweight to adapt the flywheels 6 bolt pattern. My clutch and flwheel are balanced to themself so does anyone know if this will through off the balance using the counterwieght. also if anyone has bolted up a lightweight flywheel or anything did you use the automatic counterweight? Any help would be great thanks guys...

 

You need to use teh auto counterweight.

 

The big nut holds the counterweight that you MUST with any aftermarket light flywheel, and then the flywheel bolts to it with 6 bolts. The counterweight must match the series engine as well.

 

thanks alot guys
