Not really rotary related yet, but I've got a '91 B2600i 4x4 that I am prepping for a rotary swap next year. I did the swap a few weeks before christmas and its still driving great. I don't plan to do much offroading so I'm not worried about those characteristics, but it should be great for a street truck with no weight in the rear.
I'd heard that FC Rx7 owners have used Rx-8 LSDs. I'd heard that the Rx7 LSD can be used in the B2600i axles with a little fab. So, my deducing brain got me started on a project to get a low cost LSD in my truck for winter. The Rx-8 LSD is a Tochigi-Fuji "Super LSD" torque-sensing carrier similar to Mazda's "Torsen" units in function. They allow an amount of slip before engaging. Where they differ from the helical Torsens is that they use conical clutch packs. Rx-8s use them with good success so I imagine them to be great for the street, thought I have no experience with their offroad capability. Mine came from a 2006 with 30k miles. Enjoy!
