ResidentRedneck Posted October 29, 2013 Share Posted October 29, 2013 What stronger rear diffs are available? Could I swap in one from a lgt? Would I need the axle shafts? Sent from my SGH-M919 using Tapatalk Link to comment Share on other sites More sharing options...
GEE-OTTO Posted October 29, 2013 Share Posted October 29, 2013 What stronger rear diffs are available? Could I swap in one from a lgt? Would I need the axle shafts? Sent from my SGH-M919 using Tapatalk Stronger than stock 2.5i: R160, R180 that PnP easily swap DS, axles match to gearbox F/D ratio. If you are crafty enough you can fit just about any diff under the rear end, one guy fit a R200 in an impreza with a lot of fab work Also you can buy the Cusco or the Quaife units. You planning something crazy? Link to comment Share on other sites More sharing options...
Rester5350 Posted October 29, 2013 Share Posted October 29, 2013 From what little I know, it mostly depends on the fd and gear ratios. I am putting a r180 ( 3.54) into my OBXT with very little modification. Link to comment Share on other sites More sharing options...
GTTuner Posted October 29, 2013 Share Posted October 29, 2013 I believe the R160 is the standard issue LGT rear diff although I think there are aluminum and iron variants depending on the trans (someone chime in and correct me if I am wrong). The R180 is the brute. Link to comment Share on other sites More sharing options...
whitetiger Posted October 29, 2013 Share Posted October 29, 2013 the strength of the diffs is the same across all r160 that are both VLSD and open. the spider gears are the weak link. i don't see how the op would need a stronger diff with his 2.5i though. If you are looking to add a LSD function, you just need to find a take off r160 from a LGT that has the same FD ratio. other than that, you can drop $$$ on aftermarket units that also require a full build, but this will be over kill unless you track/autox the car.

ResidentRedneck Posted October 30, 2013 Author Share Posted October 30, 2013 i was thinking of converting it to RWD. no matter what diff goes in, its going to be welded. i keep planning crazy things for this car. i need to pick an idea. but i drove a RWD impreza and fell in love though. eventually it will be forced induction as well, but thats still being decided inside my head.

sheppo9 Posted October 30, 2013 Share Posted October 30, 2013 Why not just weld the one in the car now? Link to comment Share on other sites More sharing options...
ResidentRedneck Posted October 30, 2013 Author Share Posted October 30, 2013 Will it hold? If it will then I'll go for it. Sent from my SGH-M919 using Tapatalk Link to comment Share on other sites More sharing options...
whitetiger Posted October 30, 2013 Share Posted October 30, 2013 yes, it will hold, and drive like crap too. not sure what your plans are other than RWD conversion, but if you want to be able to turn on the street, dont weld the diff. Link to comment Share on other sites More sharing options...
ResidentRedneck Posted October 30, 2013 Author Share Posted October 30, 2013 That's not entirely true. I daily drove a jeep with 36inch mud tires and a welded diff. It wasnt bad. Also, buddy's 240 has a welded diff. Not bad to drive at all. Sent from my SGH-M919 using Tapatalk Link to comment Share on other sites More sharing options...
