i was wondering what the diffrence between a B16a throttle body(89 honda integra) and a 91 Integra RS throttle body were. Im not sure but they look the same to me or is one bigger than the other and if so by how much? and will they bolt right on?
if any one can help please do so! i know it sounds like a stupid Q but i need to know. THANKS

 

They are both 58MM and yeah they'll bolt right on.

 

thanks man
