reason im looking to get more is because a got beat by a swaped 2.4l neon

Im just wondering what else I can do to help my car pull a little harder on the high end with out losing my low end punch.
now my car is a 2.2l auto so I dont want to dump a ton of money trying to make a na fast. so far, powerwise, I got a impreza intake, perrin lightened crank pully, grounding mod, a full motor tune up(plugs, wires, fuel filter, ext.) and a dynomax muffler. my exhaust will be getting redone very soon to a full 2.25 from the headers all the way back with a fresh high flow cat.
so what else can I do get that little edge? without going internal on my motor.
thanks
