I have three really good friends with hondas, and they've all steered me in a different direction on this one. One of them says that all b series oil pans are the same. The second says b16 and GSR pans are the only two that are interchangeable. The third says that the B16 pan is unique and can't be swapped with anything else. I'm inclined to believe the second one, but whats the truth here?

 

all b series pans are the same and can be interchangable.

 

all b series same
