I have an F22 engine (1990) with the stock Honda throttle body. What other years or other engines can be a donor? Are all OEM throttle body mounting holes in the same format? Then which bore sizes will be interchangeable?

I think my bore is 60mm. What OEM throttle body is larger, and will simply bolt up to my plenum/intake? Bored out t-bodies still have the plate constriction point.

Thanks for viewing, and please post your comments.

 

I'm sure somebody must have put another engine's throttle body on his car, for a swap.
