NA internals

What kind of engine internals for a RSX-S are out there and who makes them? Do you know an general price range?

A general price range is hard to say, but Crower, Toda, and Hytech make internals for the RSX (there are some others too). Search http://forums.clubrsx.com . The latter 2 make complete engine kits for the RSX.

Also, get boltons and see how you like those, and then move to internals.

Or you could just go to http://www.clubrsx.com and go to the parts store. The forums will give an idea on whats better, the parts store will tell you how much. Oh, yea good idea staying NA.
