If they're pre 93 1600 diffs they'll be 4.3:1.

You'll need to look at mk2.5 diffs to get a 3.6:1 CWP.

Thanks for the offer but I believe the 1.6 diffs were 6.5” and the 1.8 are 7”. I could be wrong
The 3.636 diffs were in the NB8B Mx5 or in the mk2 626

3.63 ring & pinion for the MX5 is pretty rare, you cannot buy them new any more and they were found mainly in Australian market NB's. I tried to get one from Oz some years ago but the cost & shipping was too much. Why do you need the 3.63? its way too tall for the engine. Most Aussies complained at how gutless it made the car.





Never under estimate the ingenuity of an idiot!

chillis, its more of a back up plan / just in case job, as i am running a 1.8 turbo with circa 250bhp on a 6 speed box with the 3.909 lsd in a MNR Vortx
and it may just squeeze 60mph in second !!
