While there are ways to make your Mazda 3 quite fast it is not cheap or easy, and will require extensive involvement from experts. You would be far better served to look for a second-hand factory turbocharged high-performance Mazda MPS model, or buying a Subaru WRX, or Volkswagen Golf GTI, to get your high-performance kicks.

The best way to make a Toyota Corolla faster is to trade it in on a Subaru WRX or Volkswagen Polo GTI. While Japanese cars are known to be loved by boy racers for their easy ability to hot up, the last few series of Toyota Corolla have next to no options for hot-up parts as these cars focus on excellent reliability rather than tar-burning performance. If you have a need for speed, consider looking to the Subaru WRX for a practical four-door Japanese go-fast car, or a Volkswagen Polo GTi for a fast car at a similar price point to a Corolla.
