Your best option aside from getting an overseas SVX 3.70 rear diff is to swap the r160 3.70 ring and pinion gear into your SVX r160. You cannot swap the WRX r160 in because the SVX axle shafts will not fit the WRX diff, and the WRX axle shafts will not fit the SVX rear knuckles. You maybe able to find a used diff to get the gears from, but if not you can still get them new from Subaru and I think ralli spec.

Actually thats not a bad idea, get the euro/jdm vtd trans and tcu and worse case get wrx 3.7 gears and swap into svx diff.
If I was thinking about staying auto that may be my plan.
