jono Posted June 7, 2018 Share Posted June 7, 2018 I knew I threw one of these out with its PT 4WD 3 speed auto Now realised I have tossed another Vortex turbo FWD ! At that stage did not want fwd and only wanted the casings for a single range awd box Having now driven fwd for some time now know I tossed a rare thing.

Numbchux Posted June 7, 2018 Share Posted June 7, 2018 What? Subaru never used a 3.454 diff They use 3.545 in the SVX and some newer models pretty sure a PT4WD 3AT would use a 3.70 Quote Link to comment Share on other sites More sharing options...
john in KY Posted June 7, 2018 Share Posted June 7, 2018 Once had an 85 XT turbo FWD that had the 3.54 differential. Quote Link to comment Share on other sites More sharing options...
silverhelme Posted June 8, 2018 Share Posted June 8, 2018 (edited) In the ea82 cars per the service manual both the 3at and the 4eat used behind turbo engines had 3.454 front diffs. All others used 3.70 or 3.90 diffs. I made the mistake of using a turbo 3at in a nonturbo car and it almost killed me when I put it in 4wd on the snow.
