My MSM diff IS apart. Where should I take pics?

Also what you wrote is what I read a long time ago, that 03+ regular miatas not a torsen, but MSM diff was in fact a torsen, and actually the SAME torsen as the Honda S2000.

<p>Take pics of the inner torsen stuff.</p><p>&nbsp;</p>

Getting late to this. My diff is no longer apart. I have always understood that the MSM diff is, in fact, a Torsen.

If it makes any difference, my 3.6 ring and pinion worked fine in the MSM diff.

At anything around 275 whp or better it seems the 3.6 would be the way to go. I wished I'd had it even at 250-260 whp on track at PIR and Laguna Seca (more at PIR than Laguna)

Sorry to thread jack but who put your ring and pinion in turbofan? I'm most likely going 3.6 with my turbo exocet.

Marsh Transmission in Tualatin. Super nice guys to work with, and they took the time to explain to me what needed to be done and why. The housing apparently needed some clearancing and such, ended up costing me like $360 for them to do it, including new bearings and such.
