i have a ls vtec crx. its got a b18a bottom end, and a pr3 head. my question is, what engine did the pr3 originally come from? i think its either the 93 gsr or a b16. any information would help. thanks.

I assume that both the pr3 and the pr4 gears have the same number of teeth on them. Are the keyways in the gear at the same position to then? I asking because these are the gears/cams that came outta my old LS swap and i skunked b16s and gsr's. If the key ways are different that coulda thrown off the cam timing in my engine and resulted in more power than i would have gotten form stock pr4 gears. This is just a theory though, has not been proven or concluded in any way.
Im pretty damn sure in saying all the cam gears are the same on the b series. All stamped pr3.
Same with the b16 and type r heads ( other b series heads not sure on ) all the same casting but then modified by honda ( type r )
