Aluxes Posted June 12, 2014 Share Posted June 12, 2014 What is the difference between the Impreza phase 1 and phase 2 manual? Im replacing mine, and I hope that I bought the right one. Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 12, 2014 Share Posted June 12, 2014 Depends on which cars the two came from. Different models could have different front differential final drive ratios. This needs to match the rear differential ratio or you'll get torque bind and damage the limited slip unit in the center differential. Other than that. They'll both bolt up fine. You may need to tap the lower starter bolt hole to put a bolt or stud in to hold the starter. I've done this by tapping the hole in the trans to M12x1.75 and using a 1/2" drill bit to widen the hole in the starter, then got a M12x1.75 x 30mm bolt and 12mm lock washer from the hardware store. Check the shift linkage knuckle to make sure its the same, or just swap yours onto the new trans. Very easy to do with the transmission out.

Aluxes Posted June 12, 2014 Author Share Posted June 12, 2014 Cool! Thanks for that. The new 5sp is from a MY 01 Impreza 2.2 and its going into MY 97 Impreza OBS. I checked the final drive ratio at https://www.dropbox.com/s/1ia75cro4n1deou/TransmissionIDChart_Public.pdf and everything matches up. Thanks for the help.

86BRATMAN Posted June 12, 2014 Share Posted June 12, 2014 You'll also need to remove the speed sensor from the new trans, and install your cable in its place. Link to comment Share on other sites More sharing options...
Aluxes Posted June 12, 2014 Author Share Posted June 12, 2014 Ok. Im having the Subaru dealer do the removal and installation. I dont have the facilities or time to do myself. Thanks for that tidbit. Ill let them know. Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 12, 2014 Share Posted June 12, 2014 Both should have electronic speed sensors. They should be the same but if not they'll be able to figure that out. Link to comment Share on other sites More sharing options...
