Cool info. Is that true of the 03-05 Civic Hybrid manual, too? The helical gear is CCW?

It is probably partly due to cost. Lots of what happens here is first to immediately reduce fuel costs. That limits discussion sometimes. But I have thought about swapping the d16y5 cam onto my d16y7. I wonder a little about Cali smog testing. Also, if you use the y5 head on a y7 won't you need to swap the intake manifold in addition to the ECU and the O2 sensors? The y7 intake is differently designed . It does not have EGR. And it does not have a knock sensor. Without a knock sensor present, the HX ECU will possibly throw a CEL and lean burn won't work.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
