A t56 transmission swap will hit pretty hard on the pocket. So if you really want it this is a realistic cash nr..
Trany used or nearly new 1000.00
Clutch kit twin plate custom flywheel 1500.00
Custom transmission adapter 1000.00
Custom drive shaft 800.00.
And labor 500.00 easy.
Hope that helps

What about the "cure" for the automatic transmission? It always urked me that Mazda could not figure out how to get a high RPM and high stall transmission. Of course, I think they should have went semi-automatic and just made 1 transmission type.
What about a 4L60E or 4L80E automatic? Even something crazy, like turning the automatic into a semi-automatic. Or some secret of the auto RX-7 turbo folks....

FB Performance high performence automatics tranny for Rotary engine
Take a look for FB Perormance 4stb transmission that's holds 1050 hp 4 speed overdrive for rotary engines. here's the link www.fbperformance.com
That is scary and that sucks. I always thought it was more of a power issue, which can make sense and understandable. From your statement, however, our tranny is damn weak.

"Hey Aisin, look we dont need some indestructible stuff like the FD one, Just give us something that works and wont break that easily, does not have to be long life, just something that wont break in 3-4 years of normal use. After 3-4 yrs, who cares, u get money, I get money(rebuild/new tranny). Win-Win"
I'll just wait for BHR/Aisin upgrade tranny ... lets just hope that it wont cost us an arm and leg thats about it

Which ever you can get to market quickest is best for some of us. I'm getting REALLY tired of double-clutching every damned shift, but certainly don't want to stick another stock transmission in the car.

I thought this is the "ultimate" transmission. Why not just contact Xtrac and have them manufacture a magnesium clutch housing to mate up to their 6 speed sequential inline sports car gearboxes

The OE tranny on the '04 - '07 RX-8s is the same tranny on the '99 - 2005 Miatas.
Its good out to about 300 HP max.
Most of the insides are so soft you can bend them by hand.
I don't know what Mazda was thinking.
That said, I'm still on my first tranny and it is just starting to have problems hitting 4th at high RPMs.
I have an FD tranny in my yard.
At some point, I'll break it down and freshen it up (or, better yet, send some cash to our friend Karl since he is WAY better at it than me) and throw it in the car.
The only tricks should be the output-to-driveshaft yoke, the PPF mount and the bell housing swap.

I have nothing to constructive to add to this thread but I wanted to say
+1 to needing a replacement transmission.
When I say this it isn't a "would be nice" my 4th gear syncro is hosed.
I basically can't use 4th gear
I'm going to need a solution soon and frankly I'll try anything other than buying a new or used RX8 transmission. Upgraded Internals okay I'm good with that.
I would sooner use a rubber band and a paper plate for a drive line then buy another OEM tranny

Power!!
I was not allowed by my synchros to shift in to 5th gear at redline. That's at about 100mph. There was a TSB on those too...
