OS Giken clutches are the shit. I had a twin-plate on my 90 RX7 turbo in Japan and it was beast. It was great for drifting because it was instant grab and ZERO slippage. An unsprung clutch does wear out fast though and you need a good flywheel so the slutch doesn't eat into it with hard use.

 

The OS Giken clutch for the 300ZX comes with a flywheel. You're not supposed to use any other flywheel with their clutch. I think JUN's is the same way.

 

I've seen a couple dual plates that don't, but they weren't JDM clutches.
Have you looked into a TH350 or TH400 swap? They can hold anything with just a little investment into them. That's if you want an auto.

 

Negative, but will do.

 

Hey everyone. I spoke with DOC last night about what you were talking about. I don't necessarily want the RB26 6 speed, just a six speed. I may just have to get a custom main shaft built. I want to run the same 1-4 ratios, a slightly closer 5th and ofcourse a sixth. (Goal to reach over 200 MPH) I know it's a bit crazy but I would like to see about doing that.

 

Best bet is the Hollinger. Either way, you must have a very favorable financial situation.
