Most people start with engine performance, and they usually concentrate on the simple idea that improving the flow of air into the engine and exhaust out of the engine and improving the flow out of the engine will allow the engine to work with greater ease. The less work the engine must do pulling air in and pushing exhaust out, the more energy is left over for more important things, like pushing the car across the pavement more quickly. This is the reason that intake and exhaust upgrades are so popular, typically consisting of:

• Isuzuperformance cold air intake system.
• Stan's Headers 2 1/2 inch cat back exhaust system.
• Stan's Headers Tri-Y header.
• Stan's or Random Technology high flow catalytic converter.

Reducing the amount of weight of the parts the engine has to turn around in circles is always a good way to free up power. To parallel the first example, the less energy the engine must expend to spin its parts, the more energy it can apply to those more important things like moving from place to place more quickly. There are some bolt on parts that are popular bolt ons are typically:

• Unorthodox Racing underdrive (crank) pulley.
• Fidanza or Mueller aluminum flywheel.

Once the basics are covered, the usual choice is to work on the performance of related systems to improve flow through the engine, spark, and how the vehicle transfers that power to the ground.
