Can Someone Identify This Transmission?

I got a parts car which has had a tranny swap in it. The transmission code reads TZ102ZB3AA - N7. I've been searching and haven't been able to come up with much except that it looks like maybe an imported tranny from a twin-turbo Legacy. Can anyone verify that this transmission will hold up to my EJ22T's torque if I swap it into my car?

Turbo, BF-5? I believe 93-94 JDM spec GT... ala BF5D49P? JDM for sure. My data sheet is not so great with the autos, someone please correct me if that sounds wrong.

Running stock boost the tranny should be fine. Plus if it's a JDM most (all?) had to handle more HP than the USDM model anyway.
Found this thread on USMB:
http://www.ultimatesubaru.org/forum/sho ... 398&page=3
Says the plugs match, but sounds like it's a different ratio...4.11 or 4.44 vs. your 3.90?
Can you put the donor car up in the air and move the rear wheels and count the revolutions compared to the drive shaft?
Also, saw
THIS on NASIOC.

Thanks for the help guys.
I did run across that USMB thread before. I know the previous owner had a 3.9 rear diff in it, but that may not mean anything. I really just wanted to verify that it was from a JDM turbo model because they had more HP/TQ than the USDMs so I'm sure the tranny will hold up fine.
Unfortunately that NASIOC thread doesn't help much since nobody replied.

There are no internal differences to the turbo and NA trannies. If the tranny is healthy, you will be fine.

I was always under the understanding that the turbo 4EATs had more disks in the clutch packs for 1-2 and 3-4. Not true?

They were talking about the 5MT transmissions.
