B16 is illegal in a 7th gen. The engine has to be same year or newer than the car. Your only real option is a K20, but its very expensive.

Re: 2004 civic sedan motor swap

k20a2 is your best all around cost vs. performance. I told you why it was illegal, your not allowed to put older engines in newer cars. It's against law, not sure how else I can explain it. It probably has something to do with emissions and such.
