1994 mazda rx7 differential question.

[sarvidec]

Hi I have 1994 rx7 and I have a couple questions. Do the fd rx7 come factory LSD? I was reading on google that most came with Torsen LSD or something like that. I just put rims in my car the other day and when I turn one wheel either way the other wheel turns the opposite way or sometimes the other side doesn't move at all. I also have a Nissan 240sx and show that this type of wheel movement are indications of an open differential and not lsd. So if my rx7 does have lsd, is it worn out? Because like I was saying the other wheel turns the opposite way or doesn't move at all instead of turning the same way like an lsd. Let me know what you think. Thanks
