outchea Posted October 8, 2013 Report Share Posted October 8, 2013 So here is the deal; I currently have 2 wagons 1 Ae71 with a t50, and a busted diff center 1 Ke 70 wagon with a 4 spd etc I had a look underneath both wagos and was thinking of swapping the good diff from the KE70 in to the AE71, Both diffs to my understanding are borg and warner, (bolt housing facing the rear of the car). Is this possible ? will i have to modify anything to make it happen.....will the diff ratios be the same ....tailshaft ? Cheers A Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted October 8, 2013 Report Share Posted October 8, 2013 Both diffs to my understanding are borg and warner, (bolt housing facing the rear of the car). If they look the same they are the same. The banjo diffs are made of stamped steel plates welded together, the Borgies are cast. The borgies have the access plate bolted on the back, as you saw, while the banjos have the complete removeable diff unit that bolts onto the housing from the front. The ratios I would expect to be different, but I don't know. The auto 4K uses a 4.3, the manual 4K uses a 4.1, so with the extra power of the 4A they should have lowered the ratio from whatever the 4K wagon uses.. Use the T50 tailshaft, the rear ends will be the same, the fronts different and the lengths might be different. If you repeat whatever you did to bust the AE71 diff, the other will break just as quickly..... Quote Link to comment Share on other sites More sharing options...
rian Posted October 8, 2013 Report Share Posted October 8, 2013 If they are both Borgwarner diffs they should swap over with no problems, check the diff code on the firewall and match it up with this: The 'translator' for diff codes is as follows: First digit: A = 138mm B = 145mm C = 6.25" D = 6.62" E = 7.1" F = 7.5" G = 8" H = 9" J = 9.25" K = 9.5" L = 10.5" M = 12.5" N = 13.5" P = 14" Q = 12" R = 162mm S = 6.38" T = 6.7" U = 6" V = 10.6" W = 15.5" X = 142mm Y = 158mm Z = 202mm - no ring gear = FWD Second, third digits: 01 = 3.30 02 = 3.36 03 = 3.545 04 = 3.556 05 = 3.70 06 = 3.889 07 = 3.90 08 = 4.111 09 = 4.222 10 = 4.375 11 = 4.444 12 = 4.625 13 = 4.79 14 = 4.875 15 = 5.125 16 = 5.286 17 = 5.60 18 = 5.714 19 = 5.833 20 = 6.167 21 = 6.667 22 = 6.78 23 = 6.833 24 = 7.64 25 = 4.556 26 = 5.571 27 = 3.364 28 = 4.30 29 = 4.10 30 = 3.727 31 = 3.909 32 = 6.591 or 4.807 33 = 7.503 or 5.583 34 = 6.781 or 4.786 35 = 7.636 or 5.60 36 = 4.778 37 = 3.583 38 = 3.417 39 = 3.154 40 = 5.375 41 = 3.308 42 = 6.500 43 = 3.550 44 = 3.214 45 = 3.533 46 = 2.928 47 = 3.944 48 = 3.356 49 = 3.729 50 = 3.400 51 = 3.736 52 = 3.722 53 = 3.250 54 = 3.941 55 = 3.333 56 = 2.821 57 = 4.058 58 = 3.238 59 = 3.234 60 = 3.519 61 = 2.724 62 = 2.892 63 = 2.655 64 = 4.312 65 = 3.837 66 = 3.071 67 = 3.526 68 = 3.095 69 = 4.176 70 = 5.857 71 = 2.962 72 = 3.949 73 = 4.285 Fourth digit: 2 = 2 pinions, not factory LSD 3 = 2 pinions, yes factory LSD 4 = 4 pinions, not factory LSD 5 = 4 pinions, yes factory LSD Information sourced from: Toymods.org Quote Link to comment Share on other sites More sharing options...
tojo2 Posted March 17, 2014 Report Share Posted March 17, 2014 Do those diffcodes apply for borg warner as well? Quote Link to comment Share on other sites More sharing options...
rian Posted March 17, 2014 Report Share Posted March 17, 2014 (edited) These are Toyota's codes, they will be stamped on the compliance plate under "Axle". So I assume they will to apply to whatever factory diff is in the car. Edited March 17, 2014 by rian Quote Link to comment Share on other sites More sharing options...
ra23celica Posted June 4, 2014 Report Share Posted June 4, 2014 My November 1984 auto AE71 has the Borg Warner diff and the silver tag on the base of the rear plate says the ratio is 4.11. Just my 2 cents here. Quote Link to comment Share on other sites More sharing options...
