I’m not partial to any brands but you for sure want to get one designed for OPEN diff 29 spline output shafts (s13 is a safe bet). Some use a pair of short side vLSD stubs so the LSD manufacturer doesn’t have to cut internal splines in the side gears (ATS and maybe others). This is not one that you want. I ended up grinding new c clip grooves in my ATS diff and trimming down the internal spacer to make it work with old school 29 spline axles.

Hope that helps.

I used a later model R200, so the splines were the same as the 240SX/Skyline etc. I have a Tomei clutch type that I reduced the initial breakaway torque for. It's still a bit clunky, but all clutch LSDs are. As long as you use later versions that are compatible with the newer units, you have plenty of options.

This one sounds promising but I would confirm before purchasing. This link is also a 2 way. You could always hold out for a 1 way or 1.5 way if so desired.
