91 miata viscous diff in s5 n/a?
 

I've read the writeups on installing a miata torsen diff, do the same rules apply for the earlier years viscous diffs? I've got a line on one for practically dirt. Thanks in advance.

no. 89-93 miata uses a smaller rear diff.

the miata started in '90, but yeah, all 1.6L miatas have a different diff. you need one from a 1.8L '94-

Ok cool. Thanks for the info.
