Hi,can anyone help me with this ?

Currently i have a Honda Accord 2003 Japanese Version 2.0l Auto, it seems that i need some advice on how to make it go faster than it can do now?? any idea on how to do it ?? What should i change of cos the car is still under warranty ... if possible ..change something which is Legal too and not to MOD the car till it is too illegal to run on the road....


anyone has any idea where can i find nice 17 " wheels but not too exp.. wanted to change but can't find anything suitable >> suggestions anyone ??
