Let's get into the specifics of what a turbo kit consists of. Regardless of the type of kit you choose, certain components are essential for a successful turbo upgrade. Understanding these components is crucial for making informed decisions and ensuring that your car runs smoothly and efficiently.

• Turbocharger: This is the star of the show! It's the device that compresses air, allowing the engine to burn more fuel and produce more power. Turbochargers come in various sizes and configurations, each with its performance characteristics. The size of the turbo will affect the boost threshold (the engine speed at which the turbo starts to produce boost) and the overall power band. Larger turbos generally provide more top-end power, while smaller turbos offer quicker spool-up and better low-end torque. When selecting a turbocharger, you need to consider your power goals and driving style. Choose wisely, because this choice has a large impact on the performance of your Eclipse.
• Manifold: The manifold connects the exhaust side of the engine to the turbocharger. It channels exhaust gases to spin the turbine. The design of the manifold is essential for maximizing exhaust gas flow and turbocharger efficiency. There are different types of manifolds, including cast iron and tubular designs. Tubular manifolds are known for their better flow characteristics and can provide more power, especially at higher engine speeds.
• Downpipe: The downpipe connects the turbocharger's exhaust outlet to the rest of the exhaust system, carrying exhaust gases away from the turbo. A proper downpipe design is crucial for ensuring efficient exhaust flow, which can affect the turbocharger's performance and the overall power output of the engine. The diameter and length of the downpipe are essential factors, and it is usually a good idea to upgrade this part when installing a turbo kit.
• Intercooler: An intercooler cools the compressed air from the turbocharger before it enters the engine. Cooler air is denser, meaning more oxygen molecules can enter the cylinders, leading to increased power. Intercoolers come in various sizes and designs, including front-mount intercoolers (FMIC) and top-mount intercoolers (TMIC). The choice of intercooler will depend on your performance goals, budget, and the available space under the hood. A well-designed intercooler is essential for preventing heat soak and maintaining consistent power levels.
