I picked up a supposed Torsen diff to find out it is a clutch type 43Ring 11Pinion RX7 diff. Oh well. The price was right so I am still in need of a 4.3 LSD. I have another friend with a Miata Torsen but 4.1 gear ratio. Anybody out here in the SFR region have Torsen with a 4.3 gear set? I have the half shafts, drive shaft and a carrier support for the Torsen. Let me know if any of you have one and how much you would want for it.

I found mine locally on craigslist for $500 for the complete setup - driveshaft, torsen, axles, PPF
The dismantler didn't know how to check for a Torsen. I got the VIN and called the Mazda 800 helpline to get options on the car advising it had a Torsen. Then I checked out the "diff spotters guide" on Miata.net and went over there. Sure enough it was a Torsen. I didn't educate the guy on the differences.

See...you should have started with a 99 donor w/torsen

Probably cheaper to buy a 4.3, and sell the 4.1 than swap the R&P. Close to a wash at least depending on what you pay for parts and labor.
There are parts you must replace and tools+know how required to swap a R&P. I think the MS price for the ring gear was about $500 and there are plenty of little bits that need to be replaced too such as various nuts, bolts, and a crush sleeve that can only be crushed once.
If you set it up wrong, you risk having a lot of money into an expensive part with a short life expectancy.
