rideordice Posted February 16, 2006 Share Posted February 16, 2006 ive heard that the turbo models come with different gearing in the rear diff, i just swapped in a 5 speed d/r from an 88 spfi, before i get rid of the donor car is it likely that the gear ratio is different? car isnt running yet or i would just drive it and check.

Dylan86GL10 Posted February 16, 2006 Share Posted February 16, 2006 Look at the diff tag and see if the two are the same. My turbo has 3.7 on it. Link to comment Share on other sites More sharing options...
Subarian Posted February 16, 2006 Share Posted February 16, 2006 Turbo is 3.7:1, non-turbo is 3.9:1. You'll have some major issues in 4wd if you leave the 3.7 rearend in with a 3.9 front. Link to comment Share on other sites More sharing options...
