I'd start by putting in a cold-air intake system - something like this: maybe get a new cat-back or other exhaust like this:, you can get a chip for your vehic's internal cpu like this: should be some good ways to improve HP for not a TON of money...of course, there are always more expensive methods (i.e. lowering weight in the car, new headers, etc.), but the three I list above, I think, will give you the best bang for your buck...

buy yourself some headers, an exhaust system with piping that has a larger diameter than your stock system and get a cold air intake. Try brands like AEM or DC Sports, they make good stuff. If you want, you could also get a performance cat, which will decrease back pressure in your exhaust.

Of course almost everyone wants more HP in their ride. The question is, what's your budget? If you have a low budget, then here are a few things you can do:1) Replace your stock air intake with a high flow K&N air filter (i.e., cold air intake system) going directly to the throttle body;2) Replace your spark plugs with Bosch Platinum +4 (no gapping required) and a set of high conductive spark cables.3) Replace your stock catalytic convertor with a high flow catalytic convertor; and also replace your muffler with a high flow one.Basically, the more air your throttle body can suck in and pass through to its tail pipe, the better your fuel will burn which in turn gives more power to the engine. And all of the above will help it do just that.Now if you have some extra money to play around with, you can add turbo (or supercharger), nitrous oxide, performance headers, performance gears/pulleys/flywheel, performance fuel rail, performance fuel injectors, modified ECU, etc..But definitely do the low budget things. Hope you'll have fun modding your car!
