an exhaust, a pully kit, an AFR, or FPR and some spark upgrades would make such a diff. Then all you gotta do is tune the car. STock you put out 160, with the mods you got and the ones I mentioned you should be just about even with a VTEC (190hp). The 2.3 litr has more grunt then the smaller 2.2, more torq too. if you really want to juice it up think of a smal shot of NOS, maybe 50. or better yet if you really want vtec just buy the head and out it on your 2.3 block, now you got size and vtec.
Get an exhaust, tanabe or Greddy power extreem do great on our cars, sound deep and throaty too not thin and tinny
