it may take a little time, since the RL design was was not intended to the
sport's car audience, per se.
but eventually (1-2yr) the mods will start to show on the market.

The question that springs to my mind is... "why?"

Seems to me that you've already paid an awful lot, for a premium car.
For the kind of money you paid you could have gotten all kinds of
tricked out rides, with any kind of performance you want. Or at least
the kind of basic car that you could mod happily for days. Heck, for
that price you could buy 2 rsx's, and keep one stock just for the heck
of it.

Anyway, I'm sure there are (or will be soon) some basic thing, like
cold air intakes, lifters, chips and such. Isn't that pretty much the
same motor that they use in the accord coupes? Maybe some of that
stuff will fit.

I've lost the link, but there is some kind of online acura
newsletter/forum that may have some leads. Just google like nuts -
you're bound to find something.
