You guys ever driven a T56? Feels like it came out of a truck.

I disagree. I have driven many different cars equipped with a t-56. The feel is on par with what you get with a strong transmission. You arent going to find a tranny that feels like a miata with the torque capacity to handle a strong motor. You gotta make a choice.

With that said, I see no real problems with the stock tranny. Unless your drag racing on it theyre actually quite strong. Many other driveline components will fail before it will.

The Supra Getrag is much nicer IMO.

I agree.

One of the reasons I have this waiting to be installed in a spare trans:

Some techs were even replacing transmission on the same vehicle multiple times till the clutch pedal problem was finally discovered.

Key post from link:
"The driveline "shudder" and gear-grinding descriptions are symptoms of a clutch that is not fully disengaging. When the clutch does not fully disengage, the engine torque loads the synchros and they start to grind. The driveline shuddering (or sometimes a "thud" sound) during shifting is a milder form of this same problem.

The reason for the incomplete clutch disengagement is because the clutch pedal spot welds flex and disallow the full stroke of the clutch hydraulic actuating system.

The clutch pedals on all RX-8s are the same and they are a known failure point, which is why we at BHR strongly encourage EVERYONE to either have their pedals reinforcement-welded or bracketed (both, if you can afford it).

To perform this welding will eliminate the transmission problems you are having and, when this solves your problem, you can tell Mazda BHR says "You are welcome" as we discovered and have been on top of this issue for about 2 years (maybe longer, I can't remember).

Had Mazda listened to us about the RX-8 they would have saved a SHITLOAD of money for themselves by not having to replace transmissions (and cat-pipes, too) all day long."

Cool, and nice pic too. It's sort of nice to see this thred come back to life. I continue to come across nice FD's with auto tranys so the more options for a manual swap, the better I think. I only came across the 6spd by chance and at first I thought $2k wasn't bad but after finding a 5spd from an FD for $350, the 6spd seems a bit pointless.

No. Search for RX-8 6 speed. It is made of glass and has shattered under stock RX-8 power. It is not needed.

Try telling that to Chris Impey who had a STOCK RX8 6speed transmission in his FD and only got rid of it when he broke into the 9sec range.

Does anyone know of an FD specific auto to manual swap write up?

Yes. It is in the FAQ thread stickied in this forum.
