TurboII Ring/Pinion Sets

Hi,

I'm looking at changing the R&P Set in my Turbo II diff and was wondering if there are any options available other than the 4.10 I currently have.

I'd like something in th 3.6-3.9 range if possible.. I know there are lots of options for the 7" diff, but I have the 8" diff in my Miata!

Thanks!

What year is this from? Will it bolt into my Turbo II diff with no issues? This would be a good option.

I'm a Miata guy with an Turbo II tranny and Diff in my car. I don't know the lingo.. Would this be expensive used?

fd = 93-95 rx7
check the parts for sale forum for prices. you can click the search button for some historic prices or call a mazda recycler.

the ring should be bolt on, but the pinon... I dont really know about that since the one on FD is very short?
BTW your miata look pretty good hope to see more info about it
