Released in 2005, the Hilux 2.7 VVT-I is a compact pickup truck manufactured by Toyota. This version of the Hilux features a 2.7-litre inline four-cylinder engine that produces 158 brake horsepower. It also makes use of Toyota's VVT-I, or "Variable Valve Timing with Intelligence," engine. There are several things you can do to improve the performance of the vehicle to give you a little more power when you need it.

Skill level:
Moderately Easy


  1. 1

    Change the oil. Without doing any engine modifications, changing the car's oil regularly will improve engine performance. Fresh oil will prevent engine sludge and ensure that the engine is performing at its peak.

  2. 2

    Add a cold air intake. A cold air intake replaces the disposable air filter within the engine compartment, allowing more cool air to enter the engine. With the cool air comes more fuel and thus more horsepower.

  3. 3

    Install an exhaust system. An exhaust system can provide a larger port of exit for outgoing dirty air, eliminated back-pressure and allowing the air to flow more freely. This can increase the horsepower of the vehicle, giving you improved performance.

  4. 4

    Make the truck lighter. This is another trick that doesn't require any engine modifications. If the car is lighter, even if the engine has the same power, it will perform better. This can be as simple as emptying the boot or as complex as removing the tailgate or any superfluous systems that add weight.
