5speeds n/a's use 4.10 open or LSD(model dependent)
S4 GTU, and S5 GTUs' use 4.30 LSD
Turbo models run 4.10 LSD, have beefier ring and pinion, thicker stub-shafts, and bigger axels (need hubs also)
You can get TALL First gen. ring and pinion from mazdaspeed, but the pinion shaft has to be lenghend
I THINK that instead of lengthening the pinion, you might be able bold the first gen center section into a second gen rear end housing. I have never tried it, but it looks like it should work

Either the th350 or the th400 are both quite literally the easiest auto trannies in the world to rebuild.
But if youve never rebuilt an automatic before, then it will take you at least three tries before you get it right. Consider this.
There is a real good chance its gonna need a pump too. GM is sketchy on the tolerances for the stock ones. Best to start fresh.
Either trans is perfect for a light weight eighth mile car. Stock n/a rx7 rears will hold enough power to put you in the low 7's. Ive seen it with my own two eyes ---- what everyone else says. Tall tires are your friend though.

If size isnt an issue TH400 hands down. As mentioned, the trannys gear ratios are TOTALLY inconsequential.
The RX has the solid rear right??
9" ford / DANA and ladder bars + 33/4:11s.
