Major Horsepower Upgrade
 

Anyone heard of replacing/replacement for the throttle body?

Isn't that the mod where you replace the throttle body? :D

Probably won't do you any good. The 8's TB is not really a restriction to flow. And the ecu controls how far it is open (no matter how far you push the accelerator) based on rpm and air demand.

thanks! (I meant to ask where can I buy a throttle body for the RX8) thank you for the info
