A smaller engine?

Have you done any mods so far?

Get yourself a high quality air filter, up the pressure in your tires, fill the engine, transmission and rear with synthetic oil. Look into a hypertech programmer. They claim added HP and fuel mileage (I dont really know how they obtain both though). Headers possibly.
It depends on how far you want to go, how much money you have, etc. With an engine of that size, its always going to love the beverages lol.
