6 Speed FD?

IMO I dont think it will. They placed the Renesis engine farther back and lower on the chassis so that means the trans is lower and farther back as well. However, it might work you never know untill someone gets ahold of one, also do you really want to? the gearing will be set up differently, and might not be optimal for the 13BREW.
with some custom mounts, maybe some custom cutting blah blah, it might fit.

I don't really want one, just curious. It would be alot of work there is no question. Someone thought of putting a 3 rotor in a (fd, fc) and know that is way more work than a tranny swap.

Quaife makes a 6-speed gearset for the FD3S transmission, but for some reason it only works on Japanese spec transmissions. Kinda pricey too..

yes they do but I "believe" it costs 7-10k and is a sequential transmission..

I know Alf (soul assassin) had a hks dog mission in his Fc before he left here. It made alot of noice at idle, but well worth the money. I remember him saying he paid 10k.

I have read that this is the RX-8 6 speed is the same as that is in the Miata, S15 Silvia and European market Lexus IS200.
I believe the Silvia guys have had durability problems in just the few years it has been out. So, apparantly the transmission is not very good for turbo torque anyways.
Hopefully the trans will benifit from continuous improvements since it has so many applications- not that RX-8 or Miata need durable transmissions since they have no torque.

I think the going used price for one of these is around 1200-1500. Mating it to the rotary might be kinda tough. I don't know if there is anything off the shelf that would work.

That said, the T56 is also substantially shorter than the Mazda 5-speed (as you can see in the pictures below comparing a 5-speed I had laying around to an LT1 T56) and matching the shifter to the opening in the floor pan would be difficult without some sort of spacer, and that presents its own problems.
The LS1 version has a slightly longer (about 1.25") input shaft than the T56 version and a deeper bellhousing as a result, but it would still come short of the shifter opening. Even behind an LT1 which positions the transmission farther back in the chassis, you can see that the T56 shifter location is towards the front of the opening (3rd picture below).
