Types of 4-Cylinder Engines

Before diving into modifications, it’s essential to understand the different types of 4-cylinder engines available. They can generally be categorized into two main types: naturally aspirated and turbocharged.

1. Naturally Aspirated: These engines rely on atmospheric pressure to draw air into the combustion chamber. While they can be modified for better airflow and performance, they typically have limitations in terms of power output.


2. Turbocharged: Turbo engines use a turbine to force more air into the combustion chamber, allowing for greater power output without significantly increasing engine size. This makes them prime candidates for modifications, as the potential for power gains is substantial.
