garethr Posted March 26, 2012 Share Posted March 26, 2012 The "B" at the end of A02B means that the car was fitted with a factory Torsen LSD. Quote Link to comment Share on other sites More sharing options...

James Posted April 5, 2012 Share Posted April 5, 2012 A02B means: A - Crown wheel size of 8" 02 - 3.769:1 diff ratio B - Torsen LSD Quote Link to comment Share on other sites More sharing options...
cooke Posted April 5, 2012 Share Posted April 5, 2012 but if i dont have a lsd on my supra will it still say on the plate a02b or the other one to let me know which one to buy, its a 93 non turbo auto Quote Link to comment Share on other sites More sharing options...
James Posted April 5, 2012 Share Posted April 5, 2012 The plate code corresponds to what you have. Most NA auto cars have the code A01A as they have the smaller casing (the first A represents this), the diff ratio of 4.083 (the 01 represents this) and an open diff (the last A represents this). If you were wanting to fit an LSD, the factory option which was available for the NA auto was a Torsen LSD with the 4.083:1 ratio. This would make your code A01B (optional on the prefacelift SZ). The only NA which came with the 3.769:1 diff was the 6 speed SZ-R (facelift model). Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted April 5, 2012 Share Posted April 5, 2012 basiclt if it ends in A its open if it ends in B it torsen lsd Quote Link to comment Share on other sites More sharing options...
James Posted April 5, 2012 Share Posted April 5, 2012 basiclt if it ends in A its open if it ends in B it torsen lsd Yep, further to that, if it says 01 then it is 4.083:1 diff ratio, if it says 02 then it is 3.769:1 and if it says 03 then it is 3.267:1. If it starts with an A then it is small case (8" crown wheel size) and if it starts with B it is big case (8.7"). Quote Link to comment Share on other sites More sharing options...

David P Posted April 6, 2012 Share Posted April 6, 2012 Are these J spec B03B's 3.266 or 3.133? Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted April 6, 2012 Share Posted April 6, 2012 What engine/transmission is with your A05B? W58, 5 speed manual. I'm nearly sure thats the correct model number for the diff, it actually came from a USDM Lexus SC300 but the USDM NA Supra had the same diff for a couple of years.
