Can You Id This Lsd Please?

[Chris Wilson]

This LSD came ina R33 GTS-t I bought, can you ID it please, and if so are they convertible from 2 way to 1.5 way? It's set up as a 2 way at the moment. Thanks

don't know who makes that LSD, but to convert from a 2 way to 1.5 way requires a teardown and replacement of some parts in the cam system. that is one clean diff though.

Judging by what is clearly some sort of spring which is part of the internals of the diff centre, that's not Nissan centre or the 'usual' type of clutch pack LSD. Probably some sort of aftermarket LSD and in that case doing any sort of work on it could be 'difficult'.

Someone has e-mailed me to say it looks like a Cusco RS type. In which case I should be able to rotate the pressure rings and convert from 2 way to 1.5 way myself, with no parts needed.

Well if that's what it is and you know what your doing........I did say 'could'.

I pulled the diff out this afternoon and took the LSd out of the casing. i believe it IS a Cusco RS, although there was no makers logo on it. The centre section has two possible ramps, an equal angle ramp set that gives the same preload increase under acceleration and decelleration, which is how it was set up, and a "1.5" way ramp set up, that gives more preload gain on acceleration than on decelleration. I have rebuilt it like tat, hopefully slow corener understeer (push) will have been helped or eliminated, and it should be more of a circuit race diff now, tahn the aggressive drift type it was before. At least it was a cost free excercise, if it helps i will know in what direction to proceed. I fancy an OS Giken LSD, I believe these are fully user adjustable with variable preload and other trickery. has anyone any direct experience with them? Thanks.

The springs put the preload on the plates, governing the torqu at which the plates start to slip.

Its looks like a cusco RS too me.

Looks identical to mine in my R32.

I think it can be paulled aprt and the casing set up to become a 1 way or a 2 way from memory.

check this link it may help.

Thanks for that, I have adjusted for 1.5 way, a clever design! Cheers.
