demuire Posted May 20, 2004 Report Share Posted May 20, 2004 I've managed to find an R31 LSD diff complete for a pretty good price (well I think so anyway), not 100% sure if I'm going to get it yet... Would anyone (Junior?) be able to point me to roughly how much it would cost to shorten? The only quote I've been able to get so far (from a generic diff place) has been closer to $800 which I thought was a bit high (considering Junior set the whole diff up inc new discs, bearings etc for $1000...). Or would anyone be able to hook me up with somewho who would be able to do the shortening / welding of mounts? Any ideas? Quote Link to comment Share on other sites More sharing options...

I'm in the same situation as this atm anyone got any info on r31 lsd conversions? ive searched a number of forums and everyone seems to have mixed opinions but nothing really solid Quote Link to comment Share on other sites More sharing options...
Junior Posted November 29, 2005 Report Share Posted November 29, 2005 Hey just browsing around... and I see this. Yes I have done the conversion.. Though it was in a KE55 Sedan, but I think it would be the same as a KE30. So Fook... Did you ever get around to doing this, as your post is dated early 2004. For starters. Find a complete R31 Skyline axle.. Your choice should depend on the ratio in which you would prefer.. R31 Skyline Manual - 3.7:1 28 Spline axles R31 Skyline Auto - 3.9:1 28 spline axles R31 Pintara Manual - 3.9:1 25 spline axles R31 Pintara Auto - 4.11:1 25 spline axles. Next job is to work out a length... I can't remember the length that we used, but i assume it was near standard length, maybe a touch shorter. We shortened the r31 Housing by a total of 130 mm. Before cutting the housing up.. Make sure to measure the overall length of the housing only, as what the shortened legth is, is how much you shorten and repline the axle by... The borgwarner diffs have 2 different length axles in them.. You use the shortest axle still, tho it now ends up as the long axle. Measure the differnce in axle lengths, and this is how much the housing will get shortened by on the opposite side to which the short axle was fitted. Now the other side will be shortned however much you want, nut keep in mind that the housing has to be shortened a minimum off 100mm in order to respline the axle. Get axle resplined by engineering shop to specified length.... No start putting it all back together :hmm: If you find you need more info email me... or add me to msn [email protected] Cheers Jamie Quote Link to comment Share on other sites More sharing options...
