what siz throttle body does the tc have stock?

 

damn nobody knows

 

i think it is somewhere in the neighborhood of like 65 mm, because there were lots of people who wanted to do things like a mazda rx-7 or 8 tb swap because it was 70 mm, and i think the one for the rx-8 was a dbw system made by the same company that makes the tc's dbw system, so they are easy to swap. try searching, it is on here somewhere.

This throttle body space for the Scion TC is 70mm so I would imagine it would fit the stock throttle body meaning it's probably 70mm

 

no it's not 70 it's 65

 

sorry, didn't mean to spread mis-information.

i don't know why people are so curious about this mod, i am yet to see a memorable post about this actually doing anything worth the trouble.
