I have done alot of research on a 94+ B/H series swap, and Turbo D, and I have looked at my options, and thought about what I want.

I have come up with this:

#1 Keeping it street legal.
#2 Being able to pass Cali emissions, and laws. (Moving there for school in October)
#3 Keeping decent MPG.

I have searched for topics on the B18 block and B16 head, and have not come up with much, and I wanted to know more about the flow of a B16 head compared to the B18 head, and if I would be beter off going with a B18 block, and a ported B16 head?
