Could anyone tell me the size of this throttle body? I am curious, i am installing a new throttle body on my setup and wanted to know how big of a jump i was going. If anyone know the sizes of these throttle bodies that would be great:
D15b2
d16a6
d16z6
b16a1
b16a2
b18c1
b18c5
h22a4
Any and all of your help would be appreciated. I did a search for several of them but did not find any EXACT answers, so i figured i would just start a post.

Thanks,
Matt
