Ok so mazdatrix sells a torsen differential for 84-92 rx7's. My question is, does anybody know what this torsen unit is actually out of? Im assuming a miata, but I didnt know if they just swap in. If someone can tell me what the torsen is actually from I could get it way cheaper.

 

Is this not the one made in OZ by guru motorsports?

 

i belive its the competition torsen made for spec miatas. but if fits all mazda 7" ring gears. Like the stock miata torsen but beefed up.

 

Yeah, it's definately not the Guru item.

 

there isnt an actual mazda part number for this beefed up torsen is there?

 

There is, but I don't have it handy. I got mine from Mazdacomp a few years ago.
