Losing weight in the car is the easiest way to make it slightly faster cheap... mainly because simply removing unnecessary parts costs nothing.
Pull out the spare tire, jack, medical kit, your trunk mat and any plastics inside the trunk that you can't see when the lid is closed. Remove all the extra unnecessary plastics from inside the engine bay(engine cover, etc).
Next time you replace your battery, use a lightweight Dry Cell battery.
How far you want to go with the weight reduction depends on how serious you are about gaining speed and how willing you are to sacrifice luxury in order to get it. You could take it as far as removing the back seat, and all the unnecessary interior parts, including the radio/speakers and even the passengers seat.... but I'm sure you wouldn't want to do that if you street-drive the car.
Also, drive with the gas tank pretty low in weight when you plan on racing.... gas weighs about 6.5 to 6.75 pounds per gallon... so a full tank of gas in our cars weighs about 139 pounds. If you only keep about 3 gallons in the tank when doing a drag race, you'll be about 115 to 120 pounds lighter than you would be with a full tank.
You can also drain your windshield washer fluid reservoir to lose another 8 or 9 pounds.
Hardcore racers also remove their air conditioning systems from the car because they are both heavy, and draw power from the motor because there is an extra pulley to spin. That extra pulley doesn't take away much power when you have the AC/Defogger turned off, because there is a clutch in the system to disengage the pulley from spinning the A/C compressor, but it still draws a little bit of power all the time(negligible).

Cheapest route would be:
-Motordyne 5/16 plenum spacer
-Replacing your cats with either high flow cats or test pipes (Fast intensions, Berk, Motordyne are popular and effective)
-Exhaust
TUNE
Also, redoing your gears will make you "pull" hella faster than stock. Lots of people say that redoing their gears made their car beast while still naturally aspirated.

Op, I got HKS exhaust, MD5/16, JWT pop charger w/ Ztube and the power gain I got is not all that great. The HKS was pretty expensive and the other two mods was fairly cheap. What I am trying to say is that, modding this car right will not be cheap. Save money and time and get FI and the right tune. This is where you will be happy with the power gained...
Changing the final drive gears. You currently have 3.5 gears with vlsd. Most people, including me, swapped our pumpkins to 3.7 gears or shorter (higher?). Having shorter gears basically makes you rev faster, therefore being in the powerband sooner. So you get faster acceleration at the cost of higher rpms while cruising, and slightly less mpg due to the higher rpms.
And to add on to what Silencer said, your speedometer will be off. EX- I went from 3.5 to 3.7 gears, when I'm doing 80mph my speedo reads 90.
^ Oh so I'm not going crazy! After I got the 3.7 installed, I felt like the car was going slower than the speedometer was reading haha. I read somewhere you can get the speedometer re-calibrated?
