Quoted from the 2nd Gen FAQ
Can I install the RX-8 6 speed transmission into my 2nd Gen RX-7?
5th gear on the FE tranny is the same as the 4th on FC trannys anyway, so there is no real advantage of using the RX-8 tranny if you are thinking that the 6th gear will be a extra gear for an overdrive, and actually 6th on the FE tranny (.83 vs .71) is shorter than the FC, resulting in lower gas mileage at highway speeds.
Using a RX-8 tranny would be like adding a extra gear between 2nd and 3rd to a standard 2nd gen RX-7 M or R type transmission. If you look at the gear chart this does not match clearly, but in simplified operation it is the nearest description to what happens.
Add in, that the RX-8 6 speed transmission is also about 4 inches too short, forcing you either to relocate the shifter 4 inches forward in the car, or move the engine 4 inches backward (towards the firewall) to make it fit in the stock shifter location as well as fabricate a custom drive shaft and transmission mounts."

So, would it be worth all the trouble if your looking to make a 10 second car?

the rx8 uses a turbo clutch. rx8 starter. driveshaft is also t2 size yoke. so that's easy
you're on your own for a trans mount, as the rx8 has a powerplant frame like the FD/miata/rx8
THEN its got no speedo drive in the rx8 trans so you're on your own there too.
