I have an FC race car (BP13b).
I have a broken RX8 6 spd tranny.
I have been looking around for another but all are pretty expenssive.
A miata 6 speed looks the same and has the same gears and are about half the price.
Could it be possible that the RX8 bellhousing will bolt right up to the Miata tranny?
If this is possible I could ave a lot of $$

 

I would say that even if it does in short order you'll have a broken Miata tranny.

 

I didn't break the tranny. I got it broken.
A bridge port 13B wont break a tranny.
You need about 250+hp to break one.

 

Hp doesn't break trannys, it's abuse, torque, and lots of traction that do that.

 

 

i concur

 

I'd like to know this for reference too.

 

it certainly looks like it does. input shaft might be a little longer as it is for the 5 speeds, but it is the same trans pretty much
