Q: This Mazda 6 has a 4 cylinder, and is a 2009, but the grand prix has a 6 cylinder and is obviously faster. How fast could i tune the Mazda 6, and how much would it cost me? It is a 2008 grand prix
A: The Mazda 6. The Pontiac might not be faster. It is bigger and much heavier after all. The Mazda 6 is the best handling and most fun car to drive in its class. Around a race track, the Mazda 6 would win. Very reliable and good on gas too. A Cold Air or Short Ram Intake would give the car around 10HP more to 170HP and an exhaust system would give it another 10HP so it would be 180HP. A turbo kit would add at least 100HP, but costs $3000-6000
