How can I make my 05 sunfire Fast?
Buy a Corvette !
I'm 17 and don't have that kind of money.
If you have no money then you can't make the car faster.... add a new fresh air intake and larger exhaust to the car...the 05 Sunfire is not worth making faster no way to get your money back, save your pennies and buy a corvette. You can get an 80"s corvette for a few thousand dollars.
At 17 a slow Sunfire is appropriate.
