Can anyone ID this f/d?

Removed from my JDM FC RX7 turbo. I bought the car for parts only!

I\'ve never driven the car, but I removed the diff and opened it up. It looked like it had been played with before (there was a load of sealer round the flange).. I removed it and there was jap writing inside, wiped off once I had been playing about with it though!

Anyway, only number I could see without stripping it down further was (A P012)

Any help please? :confused::confused:

I totally forgot to count the teeth and worth out the FD ratio

If its from an FC it might be an FD torsion diff as it fits into the OEM FC housing - its a good upgrade for a track car, might be worth checking with the FD guys - would explain why its got sealer around it etc

This might also help as some diffs fit into the Miata as an upgrade:

Thanks, hopefully someone will be able to identify it!

I\'m going to use the diff in my mx5, bolts in! Just need to make a brace up for it!

Don\'t forget the half shafts etc, I know speedline import\'s MX7 just bolted in the OEM FC drivetrain and got the propshaft shortened

Yeh, i\'ve found someone who makes custom drive flanges, so I can run the FC half shafts, so no cutting and welding of shafts!

Just need to get the prop shortened!

Its not a stock FD Torsen diff for sure and it doesnt look like the stock OPEN diff from an FC.
