styler Posted February 3, 2012 Report Share Posted February 3, 2012 (edited) Theres only one diff that somewhat bolts in but it has its own issues, its the 8 bolt d series out the ta22, and I think a t series 10 bolt centre can be fitted. The leaf spring pads are 20mm out or so and so can be forced on but wear out bushes rapidly or do it right and relocate spring pads inwards which is a bit of work. http://www.toymods.org.au/forums/tech-conversions/65900-ta22-gearbox-diff-problem.html http://www.toycrazy.net/index1.html You pretty much have to shorten a diff, try r31, t series, f series converted to disc or the other less common alternatives last I remember were are g series, alfa 105, volvo dana, 9 inch ford, ford escort mkI/II, mazda rx3/4/5/7 etc You can't legally have a diff under factory length, I know it would be ideal to have 1300mm for wheels but you can't get it engineered, gotta be 1320mm or more as shortening the diff causes the track to decrease which affects stability, I know it can be altered with wheel offset but the factory wheels still have to work if ever used, hence the reason its not allowed.

parrot Posted February 3, 2012 Report Share Posted February 3, 2012 I can tell you that a TE27 T series diff bare housing face to face is 1225mm The axle from the bearing flange to the outside of the hub face is 58mm Thus 1341mm hub face to hub face.

Carts Posted February 3, 2012 Author Report Share Posted February 3, 2012 Thanks for the info but i still hoping for a diff with the magic 1320 mm disk to disk. To do the r31 diff it will end up to wide as the wheels only 20mm - offset. I must use these wheels because they look great and where free.

oh what a nissan feeling! Posted February 3, 2012 Report Share Posted February 3, 2012 R31 diff to get 1300mm need to shorten axles gets to mutch cost one axle needs to be shortened, but both both sides of the housing need to be shortened. Short axle goes into the long side, long axle gets shortened. Shortening an axle costs $150 - $180. Quote Link to comment Share on other sites More sharing options...
Carts Posted February 4, 2012 Author Report Share Posted February 4, 2012 You use two short axles in both sides but it still ends up at 1410mm total and offset diff center. So maybe shorten shorten one side more will get the center closer to where should be and give me 1320mm Thanks that will work better and should cost me about $750 Quote Link to comment Share on other sites More sharing options...
oh what a nissan feeling! Posted February 4, 2012 Report Share Posted February 4, 2012 If you do it that way the diff pinion will end up within 10mm of centre. Quote Link to comment Share on other sites More sharing options...

parrot Posted July 22, 2012 Report Share Posted July 22, 2012 I saw these on yahoo the other day. A bit ghetto, but may be ok if you are a good welder......... The translation to Japlish says, "Was removed from the 2-door Corolla KE10 late. ＫＰ６１スターレット用のＲシャフトを改造してＰＣＤを１１０→１１４，３に変更されています。 Has been changed to 110 → 114,3 PCD make modifications to the R shaft for KP61 Starlet" Quote Link to comment Share on other sites More sharing options...

coln72 Posted July 23, 2012 Report Share Posted July 23, 2012 What width is a Sigma diff? Right stud pattern and GSR's had rear discs. Would need to convert to leaves though. Quote Link to comment Share on other sites More sharing options...
KE25 Punk Posted July 26, 2012 Report Share Posted July 26, 2012 I saw at just toyota 5 odd years ago a RT104 with a t series diff in it on leaf springs. it was perfect and would fit a ke25. I'm annoyed I didnt buy it as the car got scrapped when just toyota changed focus. I have a similar problem. I'm think of LSD options for my 71 KE25. not sure what to do. I am only staying old school K motor in NA form. but would like LSD. Any thoughts? Quote Link to comment Share on other sites More sharing options...

Carts one other option would be putting flares on to cover the tyres then you can have the slightly wider diff and still have your deep dish wheels covered Quote Link to comment Share on other sites More sharing options...
KE25 Punk Posted July 31, 2012 Report Share Posted July 31, 2012 sounds like you still may have to modify the archs so the wheels don't scrap. That sounds ok if the flares are never coming off I suppose. Quote Link to comment Share on other sites More sharing options...
parrot Posted July 31, 2012 Report Share Posted July 31, 2012 You really need to modify the rear guards anyway, otherwise the flares available don't sit correctly Quote Link to comment Share on other sites More sharing options...
