Which tb is bigger.I was on a local forum and this guy said he bought a h22 swap from a friend and it has a type R tb on it.Someone on the board also said the R tb is 3" and the H22 is 2.5".I tried to convert that into MM it came out to be 74mm for the Type r and like 65mm for the h22.

 

the type R is not 74 mm.

 

I know thats what i said.ERE throttle body's are 70mm and thats already huge.
