how would a car performance be affected if a Throttle body from an automatic car was put in a manual car, same engine (D16y7).
checked the part numbers at Honda.com and they differ.

would this significantly impact the idle and low RPM power to the car?

thanks for the help!

 

not at all. same motor means the TB opening was the same size. honestly what makes an automatic an automatic is 98% electrical.

 

It may impact the idle, the idle air control valve is different for whatever reason, even though they look the same.

 

people convert automatics to manual. The throttle body should be the same aside from the fact it has the cable from the transmission going to it.
