r31 LSD

[Guest 1200ute]

Does the R31 LSD centre fit a regular R31 Skyline diff housing and axles, etc?

Yes, as long as you are talking about the live axle Borg warner 78 series diff LSD (as in skyline silhouette/SVD GTS1-2, open centre in all other aussie skylines), then that is a straight fit replacement centre in a skyline diff. I don't think it will fit a pintara diff, they have different axle splines.

The japanese HR31 models have IRS, and their differentials are completely incompatible with the aussie live axle rear end.

I hope that helps.

Exactly what i was after, tanks!

On another front, i have heard some bad reports about the Borg Warner LSD. I am getting a diff shortened to put in my project car so should i look for another LSD that would fit the live axle housing? Is there any (no more than $500)?

Hmm not much at that price range. The clutch type LSD in the silhouette/GTS is prone to wear, thats about all I've heard problems wise. You could get an earlyish XR6 LSD, or one from a VL turbo, or some of the V8 commos or falcons. All the LSD centres from BW/BTR78 series diffs should fit.

There is a company called http://www.4wdsystems.com.au who make a diff centre for the BW/BTR 78 diff called a "LOKKA" . It isn't an LSD as such, it either locks or unlocks (no degrees of torque split like an LSD) dependent on power/cornering etc. Read more on their site. Basically its like a detroit locker (in function, if not operational principle) but quieter.

Should be about 650 or thereabouts for the centre, new.

Some R31 forum members are trying to bulk buy LOKKA kits for their diffs...
