Sooo I thought I'd never get a Honda, but I somehow got convinced to get one, I found one for 300, 5spd d16,,, I want to run ehh 15 psi,, I know nothing about Hondas so please feel free to comment and call me a noon,,, anyway, I got money, and time, so what will I all need for 15 psi?

 

Well, for starters, you'll need at least half a clue as to what you're talking about. PSI doesn't mean a damned thing. Forget about it. Once you've done that, go read these.

And once you've done that, search and read. Look at other people's build threads. See what they've done successfully and unsuccessfully. Put in just a single iota of effort. We aren't here to spoon feed.
