All race brothers,

OK guys I just bought a new RSX type s and I have $2,500 to blow on my new car. First what should I do? Hit it up with the engine as far as preformance upgrades ?? But should I wait for the engine because it is brand new right?? I need like serious professional assistance and there is no one professional in Florence, Alabama. This Car will be for serious Street racing in the future after I put some miles on it. Come on guys 2500 dollars how should I spent it??
