GSL-SE clutch

Hey does anyone know if the clutch from a GSL-SE will fit a 12a car?

Different diameter of the clutch disk/pressure plate. You need to get the correct one for your car.

Check out Mazdatrix.com for more info regarding clutches that will work:

Notice that up to 1982 cars, they use a 215mm clutch, pressure plate, and flywheel. After 1983, they went with 225mm parts. Hope this helps,

An SE clutch will fit a 12A, if the engine is a true 83-84-85 12A with the correct sized/balanced flywheel for the 83-84-85 12A engine.Mazdatrixs' site can also help you to identify the correct flywheel, if your not sure about yours.Just dont mix and match flywheels.

What steve said. There are pretty much two types of N/A clutches in common use, '74-82 and '83-91. The difference is the early clutches use a 215mm disk and the later ones use a 225mm disk.

The REPU used a weirdo arrangement from the factory, but the flywheel from any other '85-earlier 13B can be fitted so a "standard" clutch can be used. Furthermore I think the RX-8 still uses the 225mm setup.

My '85 (12A) currently has a clutch disk from the '83 engine I killed a few years ago, and a Series 5 N/A pressure plate. It's what was lying around and still somewhat functional
