If really depends on your budget and power goal. If it has a 2.2 liter VTEC 4cyl, that is an excellent base for performance mods.I'd start with a cold air intake. That will add about 8-10 horsepower and cost about $250. It will also make your engine look better.http://www.2kracing.com/Category/Hon...take.htmlNext, I'd look into headers and a cat-back exhaust system. That will cost about $700 for the parts, but will give you a big horsepower gain. It will also make your car sound a lot nicer. http://www.2kracing.com/Product/1835...uct/36.htmlYou may also want to look into a short throw shifter and aftermarket cam gears.http://www.2kracing.com/Product/1178.htmlHope that helps!Don't listen to all these people recommending turbo kits. VTEC motors have a stock high compression ratio which is COMPLETELY unsuitable for a turbo kit unless you change the heads, cam, and pistons. That would cost an arm and a leg! VTEC motors are designed to make a lot of naturally aspirated power without a power adder such as a turbo or supercharger.
