Frank Bullitt Posted November 17, 2018 Share Posted November 17, 2018 (edited) As Scooter said or you can put the internals from that in to yours. Personally it would strip the lot and rebuild using new OEM parts from Toyota. Whilst apart it would also give you the opportunity to give the important parts a DCT treatment for extra strength/longevity. Edited November 17, 2018 by Frank Bullitt Spelling.

philw99 Posted February 21, 2019 Author Share Posted February 21, 2019 (edited) Update to this thread, finally! i work at snails pace on most jobs unfortunaley I've had the crown wheel and final drive pinion removed from the Lexus SC430 Diff, now the big question.... is this the correct one? The only identifying marks on each part, crown wheel 0040524Y (Last 3 letters or numbers are hard to make out) Final drive pinion 0405251 (Really clear) Number of teeth on the crown wheel is 49 Number of teeth on final drive pinion is 15 My simple maths 49 dvided into 15 = 3.266666666666667 Picture attached, it's a 200mm crown wheel as well, can anyone tell me if this will fit in a Supra N\A small case diff? My current Diff "A01A - 4.083:1; small case 200mm; open" Edited February 21, 2019 by philw99 (see edit history) Quote Link to comment Share on other sites More sharing options...
AC93 Posted February 23, 2019 Share Posted February 23, 2019 Ive had read of this swap on the Supra US forum and it should be a straight swap Quote Link to comment Share on other sites More sharing options...

My current Diff "A01A - 4.083:1; small case 200mm; open" Hi Phil. As both Scooter and myself said above, it will fit. You just need to strip your diff with the A01B & 4.083 swap ratios then put it back inside.
