But at the end of the day you would have a rebuilt MTX75 with the diff that you wanted.
Or you could have a used Mazdaspeed3 trans that has been flogged by your typical Mazdaspeed3 driver and has ?? miles left on it(and especially the diff)before it fails.....
I know which choice I'd go with...
On the other hand..It could be a potentially interesting swap.
Kudos for even thinking about it-I hadn't.
I don't know that much about that trans....do some research and let us know if they are reliable.
Good luck with the various Mazda Forums though- in the past I've hung out a little on some of the Mazda forums and while I like their cars(I own one now),I avoid Mazda forums like the plague.
You'll see why when you go there..
