I have a '92 usdm ys1 GSR transmission and I'm trying to find out what the tooth count is on the ring gear since I can't seem to fid it anywhere after searching for a while. I'm looking to install a JDM lsd and it's supposed to be a 4.4 FD like my GSR but it would be really nice to know the tooth count of my GSR so I'll know even before I open it up.

 

I believe the 4.4 fd has 66 teeth.
What transmission is the JDM lsd out of?

Not sure yet but given the circumstances I went ahead and bought it and should have it tomorrow. I'm pretty sure it has the same tooth count as the GSR, worst case scenario I can always resell it.

Thanks for the help mike, I'm surprised nobody else chimed in yet?

pretty sure it's on the FFSquad's b-series tranny page. 66 / 15 == 4.4

 

yeah 66 should be the 4.4 the 4.7 is 67

 

another thing you might run into is whether or not the fd bolts up to the lsd.

I already know it won't line up since I've had my tranny open before, thats why I hope it drops in. Otherwise I'll have to sell it but I should be ok, the guy seemed knowledgeable about it. I'll know here very soon.
