BIG THANKS TO ROGER!
He helped me out with a pressure plate he had from his oldschool 13B 4 port that mated to a lightweight flywheel on that motor. The one he gave me works, because it's for an oldschool 13B 4 port (from 70s RX4/REPU?), I think it also works on 12As. BUT OEM FC3S CLUTCH PRESSURE PLATES DO NOT WORK WITH THIS FLYWHEEL! YOU HAVE ALL BEEN WARNED! |
Just to clarify, all 83+ 225 mm pressure plates wont work.

From tweakit.net:
We supplied the flywheel to suit the 12A/13B 4-port/13B 6-port gearbox which comes with the non-turbo engine for all non-turbo RX-7s upto including gen 2. The only other type of gearbox likely to be fitted is the gen 2 Turbo gearbox. The turbo gearbox requires a 9.5" clutch and the 12A/13B 4port/13B 6port all use the 8.5" clutch. |
Yea I don't think I've ever seen a pressure plate with a lip on it like that, I'm still a bit whoozy from all the beer, but I can't recall seeing a lip like that on any flywheel I've ever slapped in, pretty much all of them run the face all the way to the edge as I recall.

I replied to him again clarifying the situation and summed up all the points brought up in this thread.

You have done more work on turbo cars though haven't you? They are different from stock N/A stuff. I got a pressure plate from Roger, and his oldschool 13B 4 port had a light flywheel too, it looks exactly the same as mine (which is why the clutch pressure plate works). The plates are much different from stock S4 and S5 stuff that we compared while we were there. There's no way a stock S4 or S5 N/A clutch will work with this thing. Edit: The clutch DISCS will work just fine, but the pressure plates do NOT. |

Mike said he looked at his RB lightweight but I wasn't around to talk to him about it so I hope he posts something..
I was actually at my garage snapping pics.. Roger has got the pressure plate I was going to use so I couldn't shoot reference pictures.. I'll do the best I can to illustrate.. |
This is a clutch pressure plate from a carbed 4 port 13B that goes into a REPU/RX4 (as is my understanding)
|
my rb flywheel has a small cutout right there to clear the spring on the pressure plate. it also runs spacers between the pp and the flywheel
