I'm buiding up a honda challenge car that currently has a gsr motor in it. I'm only allowed factory parts for the whole car except for heads/cams, which are completely free. so my question is this, I know that there are differences between the b16 head and gsr head, but which would be a better choice to send off to a head $hop to get built. Also, anyone know which intake manifold is better between the CTR and ITR (if there is a difference)? And anyone have experience with going too aggressive on factory throttle bodies and manifolds??? I really need to know flow numbers for these things, but some input would help. :-D
