VitaminZ Posted July 8, 2014 Share Posted July 8, 2014 (edited) Hey guys , looking to swap my diff to the Subaru R180 3.9 , I currently have one available to purchase but Im not sure if its the right year and model . I know the diff should off a US 04-05 STI , but the diff I am getting is off a 02 JDM STI 3.9 , I'm just trying to ensure this diff is not a Viscous LSD and IS a Clutch type or Torsen . Or if there are specific number stamps on the ring gear I should be looking for ? I cant really tell the difference hence why I am seeking your knowledge on this . There are a few pictures attached , not sure if this helps . Any help is greatly appreciated , thanks .
