hay any one make big Throttle body for the rx-8 ??

 

i'm almost 99 % sure they dont make one but that would be a good idea to see how one would work.

 

i thought you couldn't add a new one..maybe just bore out the one you have to make it larger? but since i'm not an auto mechanic i really dunno:p

 

Throttle body on the rx-8 is big at stand but i don't know why they don't make one lol

 

the throttle body isnt a restriction in this car.

 

Indeed, in fact, the throttle-by-wire system actually keeps the throttle closed more than it would be on a conventional car. So if you go WOT, the system makes a smooth sweep to achieve ideal openings at all rpms rather than just snapping the butterfly open.

A different tb would only help when the throttle is actually 100% open, and even then, its doubtful if its actually a restriction or not. Now twin-runner throttlebodies might have some advantage, like the IRTB's do on high-performance NA 4-cyls, the idea being to optimize the tuning of each cylinder (or rotor in our case) to account for the slight differences between them.
