by

The 4G63 engine, known for its performance in the Mitsubishi Eclipse and other models, has a strong aftermarket support. Upgrading the camshaft and valves can significantly enhance power and reliability. In this article, we will explore the top camshaft and valve upgrades that can help you maximize the performance of your 4G63 engine.

Understanding the 4G63 Engine

The 4G63 is a 2.0L inline-four engine that has gained a reputation for its tuning potential. It features a DOHC design and is known for its turbocharged variants. Understanding how the camshaft and valves work within this engine is crucial for optimizing performance.

Benefits of Camshaft Upgrades

Upgrading the camshaft in your 4G63 engine can lead to several benefits, including:

  • Increased horsepower: Performance camshafts can increase airflow, leading to more power.
  • Improved torque: A well-chosen camshaft can enhance low-end and mid-range torque.
  • Better throttle response: Upgraded camshafts can provide a snappier throttle response.

Here are some popular camshaft options for the 4G63:

  • HKS 264/272 Camshafts: These are ideal for street applications, providing a good balance of power and drivability.
  • BC 272 Camshafts: Known for high RPM performance, these cams are excellent for track use.
  • FP2 Camshafts: Designed for turbo applications, FP2 cams excel in boosting overall engine performance.

Valve Upgrades for Enhanced Performance

In addition to camshaft upgrades, enhancing the valves can also lead to significant performance improvements. Upgraded valves can handle higher RPMs and improve airflow.

Types of Valve Upgrades

  • Oversized Valves: Increasing valve size can improve airflow and combustion efficiency.
  • Lightweight Valves: Reducing valve weight can improve response and allow for higher RPMs.
  • Stainless Steel Valves: These offer better resistance to heat and corrosion compared to stock valves.

Here are some recommended valve upgrades for the 4G63 engine:

  • Ferrea Valves: Known for their quality and performance, Ferrea offers both oversized and lightweight options.
  • Supertech Valves: These valves are designed for high-performance applications and are available in various sizes.
  • Titanium Valves: For those looking for the ultimate performance, titanium valves provide significant weight savings.

Installation Considerations

When upgrading camshafts and valves, proper installation is crucial to achieve the desired performance gains. Here are some considerations:

  • Professional Installation: It’s advisable to have a professional mechanic perform the installation to ensure accuracy.
  • Supporting Modifications: Consider upgrading the ECU, fuel system, and exhaust to maximize the benefits of your camshaft and valve upgrades.
  • Tuning: After installation, a proper tune is essential to optimize performance.

Conclusion

Upgrading the camshaft and valves in your 4G63 engine can lead to significant improvements in power and reliability. By choosing the right components and ensuring proper installation, you can unlock the full potential of your engine. Whether you’re looking for street performance or track-ready power, these upgrades can provide the enhancements you need.
