Are all S13 diffs LSD's?

All you can see from memory of inside is very little as there are only 4 holes of about 1.5" diameter to see inside with

Actually I didn't, that's an S13 open diff.

30psi is right though, if you can turn the two output shafts in opposite directions without breaking a sweat then it's unlikely that you have one of the standard S13 vLSDs. Or if you do, it's not working very well.

The photo you sent me last night doesn't look like either the standard open diff that I've seen or the Standard vLSD.



Try popping the output shafts and comparing them, send me photo if you like and we might be able to better guess what you've ended up with.

The drive shafts should be two different lengths (about 2" difference) unless your car was already retro-fitted with an LSD and then they might measure the same, however 10" seems too short but that's only from memory.
