f20b h22a
 

does anyone know if you can put aftermarket h22a engine parts into a f20b and if so which ones are interchangeable?

As far as i know you can interchange the crank. The bores differ in size though.

things that are not h22 parts.

crank
pistons
rods
valves.

every thing else is pretty much h22 parts

The valves ?do you how they differ ? just for my own knowledge

smaller dia.

i dont know if there is another honda motor that will work . h23 valves are the right dia but the thikness on the stem and legnth might not be the same

check the honda-tech prelude forum FAQ for all F20B internal specs.
