Would an Rx8 6 speed transmission bolt into my 3rd gen?
 

I was thinking today about this. Would the 6-speed out of an Rx8 bolt into my 3rd gen? How different could the bell housing be? It should be about the same, right?

dunno... but your sig is fucking huge.

I thought I read a thread on this somewhere before and I remember the consensus being not with a lot of work. I'd try searching to see what you can find.

Heard the same, it won't bolt up. Also, with the 9000RPM redline of the rx-8, I would think you'd need to change the rear end gear ratio

I heard that the RX-8 tarnasmissions are having a hard time holding a large amount of power, so I don't know if this would be a good idea... Correct me if I'm wrong, but isn't it the same trans as in the miata?

yeah its a miata six speed

I remember reading something about a former FD owner snapping a stock RX8 tranny just taking the car to the strip with stock power levels...

Stick with the stocker, nothing wrong with other then not being able to say its a 6 speed.

I'll make it short and sweet:

The rx-8 tranny is way too weak, the gear ratios are completely wrong, and the power plant frame won't bolt up. I don't know, but you'd probably need a custom driveshaft too.

Oh yeah, and the guy that broke the RX-8 tranny on a stock RX-8 actually broke two of them so far I think.

i think his sig is cute :p:

it won't mate up properly (easilly) and won't hold the power or have proper gearing. there is a 6-speed available for the FD out of Japan. i don't remember the company but use the search function. i do remember it being about $7k

stupid double post

Sounds like the transmission won't fit, but, how come no one has done anything with the renisis yet...like perhaps a single turbo renisis FD. I'd love to see that. I have seen few modified RX-8's though, so I guess it's coming along

Ok, thanks for the replies! Guess I'll just keep my tranny.

I def. wanna see a turbo renisis. I wonder how good it will take to boost?!

I'm just trying to be helpful here and not a smartass:
Try searching, this RX-8 6-speed stuff and the turbo Renesis stuff have been beaten to death in several threads already. :)

I tried searching for the tranny. Only found a couple threads, but with no answers.

I remember that post. It was that guy that was banned from here, "Dont_Be_A_Rikki". :)

cool, thanks. I thought it would be cool to have a 6 speed in the 7, but I guess the rx8 tranny is completly not the right thing for my soon to be 500whp rx7. haha, O well, it was just a thought.

If you want to install a 6-speed because you "thought it would be cool to have" you need to stick to automatics.

LMAO!!

<-----broke an rx-8 tranny......weak little shitbox..
