goldenvtr Posted December 27, 2017 Share Posted December 27, 2017 (edited) Seen information that the ls400 3.2 open diff is a straight swap for my small case a01b. But I cant find any info if it's possible to make it a torsen using my a01b internals. Essentially making a 3.2 torsen. (For my bmw swapped trans) Anyone got any experiance in this? I don't have the space in my garage at the moment to drop my diff off and experiment.

goldenvtr Posted February 3, 2018 Author Share Posted February 3, 2018 so i though id update this it works.i bough a ls400 diff 3.2 from a 2000vvt model, swapped the ring gear, driveshaft 3bolt flange and rear case housing, and bolted it all back together. exactly what i needed and cost me bearly anything ratios suit the getrag 420g perfectly for what i wanted . few photos before i just cracked on it with Quote Link to comment Share on other sites More sharing options...

Rowlze Posted December 12, 2018 Share Posted December 12, 2018 Don't suppose you have the part no. of the Lexus diff you brought? I seem to have purchased the wrong one as the ring is thinner than the Supra ring Quote Link to comment Share on other sites More sharing options...
Iky Posted December 14, 2018 Share Posted December 14, 2018 Did the backlash change much when you put it together? I gather if the ring gear is changed, then the backlash would now be out? Quote Link to comment Share on other sites More sharing options...
Ecosteve Posted January 8, 2019 Share Posted January 8, 2019 This is exactly what I wanted to read when i came on tne forum today . I have the 420G also and find the ratios way too small. Going single turbo soon and want it to actually build boost. Thanks for the great info Quote Link to comment Share on other sites More sharing options...

Going single turbo soon and want it to actually build boost. Thanks for the great info �� Same! Car is the garage now having the 420G installed, but when its back I need to change the diff at some point as the 4.1 ratio isnt the best when going turboooooo, 3.7 or 3.2 would be ideal Quote Link to comment Share on other sites More sharing options...

Ecosteve Posted January 8, 2019 Share Posted January 8, 2019 Does the ls400 diff bolt directly into the Supra? Same shafts and prop etc. Or do you put parts into The supra case? What power are you running through your diff? Thanks man Quote Link to comment Share on other sites More sharing options...
