They can be rebuilt assuming the housing(s) isn't cracked, which I've seen happen. I think S5 N/A RX-7 had the highest horsepower engine in front of this particular transmission. OEM-wise the Miata added a double-synchro'd second gear and helical reverse gears in the 90's but I think was it in terms of revising. Maybe there are some upgrade parts available in the Miata aftermarket world.
