A solution for LSD?

I would rather run a welded diff, and I think welded diffs are a bad idea.
All this is are a couple of steel blocks and a spring set. Not a true limited slip. Anyways if you want to learn about it then go here:

Plenty of info on what it is including pictures.
Now, alot of people say it self-destructs. This in the DSM, Honda, and even the Z communities. The PG tends to accelerate side gear wear in the diff.
Me, I'd go with a viscous. But that's me.

i agree with arro on this one. It'll work... but it's cheap for a reason. Some honda guys i used to know (they weren't ricers) called them phantom slips

Or phony grips. I wouldn't try it. I'm sure it will put a ton of fine metal shavings in your dif oil and wear everything out. I do like his idea of using clutch material, but that doesn't mean that all the extra pressure isn't going to wear out the back side of the gears. But hey, if you've got a bunch of spare rear ends lying around, go for it.

not to take over your thread or anything, but how easy would it be to put a 1990 s13 (stock) vlsd onto my mk2 s12?

Well if you can't find something from searching and HAVE to ask, make sure you at least start a seperate thread. It was way off topic and I'm known to be kinda harsh about that, and expect people to put things where they belong threadwise.
That aside, I've poked around some more, and yes metal shavings contribute to wear and even breakage, but it turns out that the real danger in the PG is that you get grip similar to an LSD, but no differential strengthening, so the added grip can beat on the weak stock open diff and all of the sudden it can go
BOOM!!!
with a good solid clutch dump or a really hard shift. Sorta like overboring a block for bigger pistons but going beyond a safe limit. The displacement is there providing more power but on a weak block so it blows up. Same diff' (har har har :lol: ).

If it's a MK2, it will work for sure. There have been at least three MK2 members now that have done that exact swap. If it's a MKI, we don't know yet. It hasn't been confirmed.

Oh, Wankel Monkey and I were just IM'ing about this and I mentioned how it's not so big a deal for FWD guys, because they like to slip the clutch more on launches with all but the full race trim cars. So he said,
"Yeah makes sense, weight is being displaced from the diff on Fwd not added." Hmm there's more of that weight transfer I was talking about in another thread. But you see how they can more often get away with something like a PG, right? Although even the FWD guys have problems as was stated above by myself and another.
