Anyhow, to the original poster, did you replace the plastic bushing that goes in the slot on the shift lever's ball? It's commonly overlooked and accounts for a LOT of slack.

You can't swap individual gears, except for 5th and Reverse. The countershaft and the countergears for 1st, 2nd, and 3rd are all one solid chunk of metal. (4th gear isn't a gear at all) That bg ole' shaft presses through the center bearing assembly and 5th and Reverse slide on the opposite side.
Swapping FB gears into an FC can best be described as pointless effort, unless you REALLY want RB gear ratios. It's the same junk in an FC N/A tranny as in an FB tranny, and a Miata 5-speed tranny and some pickups and other RWD cars as well.
Just as pointless as swapping an FD tranny in place of an FC Turbo tranny - same internals, just slightly different case. Only, the FD tranny is really unsuited for anything but an FD since it requires a pull-type clutch. Mazda beefed up the thrust bearing assembly and under-front-cover assembly to handle the added abuse of the pull clutch. Could you make it live without having to rebuild your engine to FD spec? Probably. But then, some people also manage to make N/A trannies survive behind turbo engines, or at least, they don't mind the breakage.

I want Miata gears in an FB tranny... Closest ratios if you don't count the RWD 626 transmission.
Strongest gears seem to be the '79-82 (? might be '83) gears. They have coarser teeth. At least, I abused the living **** out of my '80 tranny and it had nary a problem
They switched to fine pitch gears in '83 or '84.
Like I said, some people can make the "smoothcase" trannies live behind power. Others, well..... Also KIM that Miatas are even lighter than 1st-gens, and a 1.8l that makes 300hp is in all likelihood going to make less torque than a rotary.

um, ok I'm not going to argue, but can you explain this: if the tii tranny is much more beefier and can support well over twice as much HP as a N/A tranny, why is it lighter? Also, howcome other people aren't agreeing with you, or disagreeing with me?

The 79-83½ FB transmissions were the weakest ones, and "should be avoided if reliability is an issue"

PS - '79-80 are not FBs and use a slightly different transmission from '81-up models, they don't have a remote shifter box, and before mid-80 they didn't use rollpins to hold the shift linkage together...
