13B 1980 RX7 Transmission Woes
I recently purchased a 1980 RX7 13B that now has developed a transmission problem. It is matted to I believe a stock NA transmission.
So my transmission/clutch has some sort of issue where it makes a hell of a racket when depressing the clutch. The car will not get to neutral as it seems to not disengage properly.
I have yet to drop the transmission to investigate further as I don稚 have easy access to a lift.
The car did come with clutch kit that fits a S4/S5 transmission which I知 told, but would need a custom driveshaft to mount up to the rear.
Any help would be greatly appreciated as I知 trying to get this back on the road ASAP. Also what would be the most cost effective way to go about fixing. Thank you.

Exedy Stage 1 clutch #10806 fits all 12A-13B NA 1983-91 holds up to 196 ft lbs torque. Have put these in a number of 1st gens, good clutch without too much pedal pressure. Shop around for best price.

That's the clutch I'm running. Works great, doesn't kill you in traffic.

Tried the exedy stage 1... not enough grip for my machine; for better or worse.
I use a clutch like the one pictured (except the cheapo brand). It holds my torques in check. Not too bad for a DD clutch.

Ran a early 13B with Holley with a fogger plate and 75,125 hp nitrous shot in 84 GSL with 4.77 final drive with shimmed clutch packs that saw drag strip frequently. Ran strong,I hammered it a lot and stage 1 clutch lasted almost 2 years. It had a little trouble holding the 125 shot as it got a lot of runs on it.
That痴 the most abuse I ever heaped on one of them.
Never had a problem with regular NA use. I like the way it works for driving on the street a lot better than puck type clutch,more civilized,smoother.

Just to confirm this will fit my 1980 car?

It will fit because I believe you have a second gen 13B and they use the 225mm clutch. You could also use that new clutch the car came with and not mess with the drive shaft. The clutch that is used is determined by the flywheel being used. And the flywheel is dictated by the rotating assembly.

I have never changed a clutch, but I think what Kansas was saying is that you need a clutch for the 13B's flywheel. 1979 through 83 didn't have a 13B available.... they were all 12a's. So a clutch kit for a 79-82 or 83+ will be made for a 12a, which you don't have. You need a 13B clutch kit. I think.

So does this mean this ACT kit will work for this setup? A S4 engine with the NA trans? Trying to figure this all out, I知 not mechanical savvy.
