what is the reason for changing? there is a big difference in performance between the dc2r and an eg6. if its just for a change i say dont do it. if its for any other reasons then an eg6 is a good compromise for a car approx half the price.
i did exactly the same thing as you. i sold my dc2r and ended up getting a breeze conversion with jdm b16a, sussy mods, dc2r brakes and wheels, intake and headers...few other goodies. i can honestly say it does not compare to the dc2r, but for half the price is a reasonable compromise.
so my opinion dont do it unless you have to!
