The vlsd rears are pretty common in the junkyards now. Lots of the 2nd gen Legacy Outbacks came with them. 4.11's in the 5spd's, 4.44's in the a/t's. Look for heated mirrors, if it has them it has the winter package which came with the vlsd.
If you want to spend big bucks, a 4.44 front ring and pinion plus an obx helical front diff with a vlsd 4.44 out of an auto trans outback would be a pretty good setup. Most of your traction is on the front wheels, so that's where the lsd makes the biggest difference.
Yah eventually I might bump up to the obx heli vlsd..there about 6-800 bones on the inter-web. Gonna do a few other mods to it first.
I'm pretty sure I have the 4.11 diff..Its a 2000 Outback Sport (Impreza) with the 4EAT and the EJ22, which to the best of my knowledge and reading is the 4.11..the EJ25 OBW (and other cars) came with 4.44...then again I could be heinously wrong.
I guess it is time to go count drive line revolutions per 5 tire turns.
