I'd recommend a few books too: "Honda & Acura Performance Handbook" (great all around book for information on pretty much everything) and "How to Build Honda Horsepower" (mostly about integras and civics, but shows you what parts do for adding power; with dyno charts).
The H&A Performance Handbook would be the best bet out of those 2 books. I found it at Barnes & Noble for $21.95, well worth the price.
