I've been looking for a 4.88 or 5.12 for a while.

What's the going rate for a good used one these days? (I doubt new is in my budget)

Racingralph: What's your location?

This might be of some help. info on where to get gears from other cars for the mazdas http://www.turbomagazine.com/tech/08...ech/index.html

Right diameter, wrong length. All these gears have to be lengthened to fit the 86-91 RX7.

I went from 4:30 to the 4:88 and it's really a huge difference on the track.

The factory gearing is so tall it's dumb. I also don't understand the huge gap between 4th and 5th in the regular tranny. (The GTUs 5th helps that.) I think it's an old-fashioned way to do gearing. They'd never make a Miata or RX-8 set up like that these days.
