you're kinda stuck. the best non-turbo way to make more power is to up
the rpm's, and that means work on the crank, con rods, pistons and most
of all, cams. and you need an ecu with a raised limit. there are stock
jdm ecu's for the 91 sir crx which go higher, but it'll be hard to get
one, and i doubt it'll pass smog here. depends on which state you're in
i guess.

as mentioned by others, changing the motor is an easy solution.
regarding ecu's, i have seen a site showing how to program/re-flash your
old ecu memory, but you need to know what you're doing on that one.
have a working spare handy just in case.
