which is bigger i measured my b16 at 66mm and i think the itr is 62mm and is the jdm itr diffrent

 

Both JDM and USDM type R t/b's are the same.

 

he wasnt asking if the jdm R and USDM r throttle bodies are the same, he is asking if the JDM B16 throttle body is the same as a USDM R TB. I cant answer the question, just trying to translate for the reading-comprehension impaired.

 

ITR = 66mm --> 62mm tapered

 

whats tapered?
mine is 66mm i think its off a JDM ITR not a b16

 

buy a spoon
im me

 

get your itr TB or even b16 TB taper ported. cheaper than spoon and same damn thing.
