define faster, do u mean a quicker 0 - 60 or a high top speed?

u can fit larger wheels this will make your top speed higher a the acceleration too, but it will make your speedo inaccurate. fitting a big bore exhaust system will help, but it has to be a full system, manifold and all, performance air fillers don't really do much. striping the car of weight will help too but this can be very unpractical. fitting a turbo charger, this a dump value will help get more air into the cylinders.

getting the head polish and ported will improve things too, this is where the inlet and exhaust ports in the head are widened and then made very smooth, creates better air flow to the engine, and away from it too

it got multipoint injection if u can get it changed to direct injection it will help, would cost alot tho

uprating and lowering the suspension will help with cornering, so u can go faster round the bends

finally get the ecu chipped, it will give u better performance, do this last tho, as if u get it done first then add any thing else it will not work as well.

u are restricted as to what u can do cos it is a small car, there's not much room in the engine bay i will guess. or i would say inner-coolers and nitrous

but what ever you do DON'T FORGET to uprate the brakes, as more speed is great, but if you cant stop its not alot of good

i hope this all helps
