Harvey is correct, the FWD US is 3.700

I think you can sum up the differences between the three types of drive, by looking at the way they handle a tight corner.

The FWD has to supply all the drive force, and all the change of direction force, so the front tyres reach their slip angle earlier, to under-steer.

The 4EAT depends on how much rear drive is applied. If the pedal is down, there is more rear drive, but if it is lifted, under-steer happens.

The VTD has most of the drive from the rear, but it also has the drive to the front to pull the wheels in the direction of change, the torque split will never drop below 36/64.
This amount of drive to the front wheels varies with the amount of steering, the tighter the turn, the more drive. The practical difference is with tight turns under throttle. The car just goes around with maximum drive, and steering grip.

Though, I might be biased.
Harvey.
Yes, you are rear-biased

If I use a JDM tranny to replace my slipping one it will be FWD only because of the different gear ratio used in Japan.

Any info would be apreciated.
Harvey is correct is saying that no way can you do this. If you installed a US AWD transmission of a different ratio, my experience is that you can do this, for a while anyway.

If you install the fuse when running a US-style (non-VTD) transmission, essentually, you make the car front drive. When we swapped our 4.111 trans, we ran the fuse with the rear 3.545 rear diff still in the car. However, this is not a great idea, unless careful. We drove the car up and around a steep drive, and broke a sprag.

The VTD power to the rear can not be disabled by the fuse. The importers have many transmissions from japan, most ARE the US style. Get one of those if you must, but know that a VTD will not work as you suggest.

Keep us posted

Thank you all for your input. I see my idea was invalid, I have come to my senses and will look for a 4.44 conversion. I just have to find someone to install it. I hate going to a dealer for service but I may have to for this. Do you think a Subaru dealer can handle the rear end transplant?

Ken,
A good transmission shop would be better for the rear end swap, and would be good for the transmission too....and probably a little cheaper than a Subaru dealer.
Make sure you get a 98-back tranny, the newer ones with the spin on filter aren't a direct swap.
