I thought I understood that the 91 didn't come with a limited slip, and I was searching for an older GTUs or GXL when I found someone with a "JDM"dif for what he says is a 91. Do you guys think this will bolt in?

 

If it's a JDM diff, it's most likely for a turbo model. If you've got an NA, you would need to change over a few parts to the TII parts.

 

there is no jdm non turbo.

 

Thanks , I had my doubts, think I'll keep looking for a GXL or GTUs unit.

 

Only the 86-88 GXL had a LSD, the 89-90 GXL didn't.

The only non turbos that had a LSD were the 86-88 GXL, the 88 GTU, and the 89-90 GTUs model.

 

yay.. i just junked my 86gxl parts car... i should of taken the lsd out of it....

 

While we're on the subject of the s4 N/A lsd, can it be swapped into the S5 N/A?

 

Yes.

 

yes
