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. :O

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.

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.

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.

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.
