Mike,
Do you have dimensions for the rx8 tranny? Is it the same length as the FC turbo ones? Does it share more similarity with the FC TIIs or the FD tranny? What about the bell housing? Is it 13BT / 13B-RE / 13B-REW compatible?
BTW gear ratios are (if anyone was wondering)
1st: 3.358
2nd: 2.060
3rd: 1.404
4th: 1.000
5th: 0.713
6th: 0.582
final drive: 4.300
the usa rx8 comes with a 4.44 rear. and the rx8 4.3 is the same part number as the fd 4.30 gear set and is priced accordingly

I destroyed 2 of them.. mostly because the Rx8 is a bit heavy.. to much weight being launched at redline with a 1.9, 2.0 sixty foot mark..
you ever think about dropping an fd tranny in it?

2nd Gear Ratio 2.27:1
3rd Gear Ratio 1.65:1
4th Gear Ratio 1.19:1
5th Gear Ratio 1.00:1
6th Gear Ratio 0.84:1

Look on the bright side. The 2-6 spread is nice and tight. Pretend 1st doesn't exist and observe:
0th Gear Ratio 3.76:1
---
1st Gear Ratio 2.27:1
2nd Gear Ratio 1.65:1
3rd Gear Ratio 1.19:1
4th Gear Ratio 1.00:1
5th Gear Ratio 0.84:1
Now you can justify a too-large turbo since the engine speed won't be dropping off so much after a shift.

Thoose arnt even close to the right gear ratios, or final drive, that looks like ratios from a v8 firebird or something.

AH CRAP! I read the 6 speed automatic on mazda.com, not the 6 speed manual...

bad news, shifter is about 2" further forward than the FC.
the attached pic is the input, main, and counter shaft. the random input shaft at the top is a 97 miata...

So with some minor modification to the shifter hole, you could technically make it work in an FC correct? Or does nothing match up under the car?
