Xany Posted October 21, 2008 Report Share Posted October 21, 2008 (edited) Just weld on some mounts and your away. These diffs need to be shortened to fit in any corolla.....you can't "just weld mounts on" as you say. The axels and the housing need to be cut and rewelded. Also most corolla tailshafts need to be shortened about 40mm as the yoke on the diff is a touch longer than the standard corolla item.

tas_ae71 Posted October 21, 2008 Report Share Posted October 21, 2008 (edited) you don't have to shorten the diff. just use wheels with a smaller offset. which tend to be half the price :laff: Edited October 21, 2008 by tas_ae71 Quote Link to comment Share on other sites More sharing options...

furryfrog Posted October 21, 2008 Report Share Posted October 21, 2008 (edited) Standard r31 diff is 1460mm.. They come in these varients. R31 Skyline Manual - 3.7:1 28 Spline axles 4 pinion R31 Skyline Auto - 3.9:1 28 spline axles 4 pinion R31 Pintara Manual - 3.9:1 25 spline axles 2pinion R31 Pintara Auto - 4.11:1 25 spline axles 2 pinion The ke35/55 rolla diff is 1320mm iirc Ive heard of people using different offset wheels on ke7x and getting the diffs to work without shortening but that should a bit annoying to me. also the LSD centres in these diffs are pretty average been a cone type. edit: for the money its a good diff none the less, will take a beating and there are plenty of minispools available for the BW GL with the sale.

The axels and the housing need to be cut and rewelded. Also most corolla tailshafts need to be shortened about 40mm as the yoke on the diff is a touch longer than the standard corolla item. as with any diff upgrade for a corolla t-series etc that i've seen you'll need a custom tailshaft of some description, thats pretty much a given you CAN just weld the mounts on, custom tailshaft and away you go if the extra track doesn't worry you also considering before i found this i was offered a ra23 t-series for $150 i think the price etc is very reasonable the centres can be pretty average, but i've found it depends on the way you drive, in my mates skyline if he just powers over out of a corner it can sometimes only spin a single however if you actually flick it out and use abit of clutch it spins twins everytime. (this was all done on private property of course) this is also the reason why i included the fact minispools and 2way mechanical lsd's are available. Minispools go for about $80-100 on ebay, and i've herd of 2ways being had for about $800 this howerver was when the australian dollar wasn't so shit! i will have it sent to the mainland at the buyers expence however i don't want anyone to buy something, have it sent all that way and think its a dud, i was going to use it in my car, but had every intention of using a minispool and putting new seals etc in I'm about to go and take some photos, and your PM has been replied "KE ping it real" Quote Link to comment Share on other sites More sharing options...

HEKTIC Posted October 22, 2008 Report Share Posted October 22, 2008 love how everyone has something to say in forsale threads just to put an argument to rest http://i10.tinypic.com/8g9i2dl.jpg that has a non shortened r31 diff in it those are stock s13 wheels 15x* with a + offset if you want to shorten it then thats your choice, but you CAN put it in a k30 onwards without shortening these days the desired stereotipical look is fitment, sitting flush with the gaurds and there you have it. yes lockers, minispools, full spools etc etc are illegal but so are half the things people do to their cars, drive sensibly don't hang skids in suburban areas and learn throttle control and you'll be fine Quote Link to comment Share on other sites More sharing options...
Xany Posted October 22, 2008 Author Report Share Posted October 22, 2008 (edited) I was stating the fact that the R31 diff is over 100mm wider than the standard corolla item, that it would need to be shortened to fit normal wheels on and to prevent scrubbing. In my eyes you were trying to deceive the buyer into thinking that the diff would bolt straight in after "just welding mounts on" which is wrong, because as you know you would still have to shorten the tailshaft no matter what. I should know, i've had one of these diffs sitting out the side for about 3 years now cause i can't afford to shorten the tailshaft.....My housing and axels have been shortened though.

kangaroosa Posted October 24, 2008 Report Share Posted October 24, 2008 I have a shortened R31 LSD in my KE30 2 door. If you want to do it properly, you have to get it cut and the flange re-welded on. Weld on the new leaf spring mounts. Then get it straightened and heat treated. Can be a costly experience, but thats what you pay for a proper job. I run 15"x7" Globes with +20 or +3 offset (can't remember which is on the front and rear). Anyway, they just sneak inside the gaurds. I also purchased a brand new 4.11:1 ratio and had the lsd rebuilt, so its tight as a drum. On a side note, I found that Commodore pads don't fit in these callipers whereas the brake place told me they would and actually sold me a set of EBC Green Stuff pads..... Maybe other brands vary in thickness and thus will sneak in, but the ebc ones are too thick. Quote Link to comment Share on other sites More sharing options...
