Uberoo Posted July 20, 2009 Share Posted July 20, 2009 For an EJ swap can I use a EA81 flywheel thats already set up for the larger clutch?I have a few of those around, EA82 flywheels, not so much. then does it still need a 720 throwout bearing? I'm just kinda curious...I have a parts EA81 that might be salvageable.not sure, I havent been able to check it out yet...god it would be good to get the subi running. hell, I suppose I could put this first gen mazda rotary in the subi...its sitting is a 70's mazda station wagon... it would have more HP but no torque...AH!!! must get subi running under subi power..

Numbchux Posted July 20, 2009 Share Posted July 20, 2009 flywheel has to match the transmission. AFAIK (and I wouldn't be the person to ask....) EA81 and EA82 flywheels aren't interchangeable. Link to comment Share on other sites More sharing options...
Gloyale Posted July 20, 2009 Share Posted July 20, 2009 flywheel has to match the transmission. AFAIK (and I wouldn't be the person to ask....) EA81 and EA82 flywheels aren't interchangeable. EA81 and EA82 Flywheels are very similar. Same depth step, and the EA82 clutch bolts on. Difference is EA81 Flywheel is about 2 or 3 mm thicker. It wouldn't be hard for a machinist to cut some meet off the back. This is just what it looked like to me comparing the 2, but I haven't actually tried it. either way would require hogging out he bolt holes.

carfreak85 Posted July 20, 2009 Share Posted July 20, 2009 I have an EA82 flywheel and clutch between my EA81T and 5 speed DR. I needed shims for the bolt holes because the EA82 bolt holes are larger than on the EA81 flywheel. Link to comment Share on other sites More sharing options...

I needed shims for the bolt holes because the EA82 bolt holes are larger than on the EA81 flywheel. BUt if it was going on an EJ, the different bolt holes would not matter. What I'm saying is, an EA81 Flywheel can be used in an EJ swap. With a 4spd D/R just by hogging out the crank bolt holes. OR....with an EA82 5spd and clutch if it simply had about 2mm turned off the base The step, friction face, and clutch plate bolt holes are all the same between EA81 and 82 flywheels. The major difference is the overall thickness. Link to comment Share on other sites More sharing options...
Uberoo Posted July 21, 2009 Author Share Posted July 21, 2009 thanks for the answers. I have an idea for a later project using that rotary out of the mazda. The rotary is in a mazda RX4 wagon. the body is missing bits like the suspension and what not. supposidly that motor makes 110 HP and 100 lbs tq(at what rpm?10,000?) the distributor for the rotary has 6 ports. 4 for the spark plugs, one I am assuming for the coil, and another one that goes somewhere...Any idea where it might go?

Uberoo Posted July 29, 2009 Author Share Posted July 29, 2009 Does anyone know the part number for just the XT6 pressure plate at schucks,napa,etc?I would rather not buy a clutch kit to get the pressure plate... Link to comment Share on other sites More sharing options...
baccaruda Posted August 5, 2009 Share Posted August 5, 2009 try a non-chain store that sells clutches for cars AND semi-trucks. Pacific in Spokane was helpful for me. Link to comment Share on other sites More sharing options...

4x4_Welder Posted August 6, 2009 Share Posted August 6, 2009 Two wires to each rotor chamber, and two coil connections. It has two coils. Link to comment Share on other sites More sharing options...
