    You can't boost a car's speed by installing performance parts. These parts will improve horsepower and acceleration to that top end speed at the end of a drag strip. Top end speed is solely the function of the gear ratios in the transmission and rear axle and to some extent tire size for a specific engine RPM. Another way is to reduce wind resistance, but don't expect a huge improvement in top end speed. Engineers have already designed into the car body low (but not the lowest) wind resistance.

    Easy and cheapest is to make it lighter.

    -Take out everything u dont need,

    spare tire, washfluid and etc in the trunk. even the back seat if u can. but then it wont be as functional.

    Tune Up

    Spark plug

    High quealiity low frition synthentic engine oil

    oil filter

    Air filter

    Mods - cheap

    -Get a performance muffler and a high flow performance air intake

    Get tire that have great grip as HP is nothing without traction.

    Mod - expesive

    -get a supercharger if u can afford it

    A chip would definatly help out, check out http://www.voloperformance.com . A less restrictive exhaust system will help, but not much, theres not a whole lot you can do to those cars unfortunatly.

    put a giant spoiler on it maybe even 5 or 6... they give you a ton of hp... you'll probably have like 450hp if you do that man
