The RB20DET engine has become a popular choice among automotive enthusiasts looking to enhance their vehicle’s performance. With the right modifications, particularly to the camshaft and valvetrain, you can unlock significant power gains. In this article, we will explore the best camshaft and valvetrain modifications that can help you achieve up to 20% more power from your RB20DET.
Understanding the RB20DET Engine
The RB20DET is a 2.0-liter inline-six engine that was originally designed for the Nissan Skyline. Known for its robust design and turbocharged capabilities, it provides a solid foundation for performance upgrades. To maximize its potential, modifications to the camshaft and valvetrain are essential.
Importance of Camshaft Upgrades
The camshaft plays a crucial role in determining the engine’s performance characteristics. Upgrading the camshaft can lead to improved airflow, better throttle response, and increased power output. Here are some key factors to consider when selecting a camshaft for your RB20DET:
- Lift: Higher lift allows for more air and fuel to enter the combustion chamber.
- Duration: Longer duration increases the time the valves are open, improving airflow at higher RPMs.
- Profile: A performance-oriented camshaft profile can enhance torque and horsepower across the power band.
Recommended Camshafts
Here are some of the best camshaft options for the RB20DET that can help you achieve the desired power increase:
- JWT S2 Camshaft: Offers a balanced increase in power and torque, ideal for street applications.
- HKS 264/264 Camshaft: Provides excellent high RPM performance while maintaining drivability.
- BC Stage 2 Camshaft: Designed for aggressive power gains, suitable for track-focused builds.
Valvetrain Modifications
Along with the camshaft, upgrading the valvetrain is essential to handle the increased performance. A stronger valvetrain ensures that the engine can operate at higher RPMs without failure. Here are some recommended valvetrain modifications:
- Upgraded Valve Springs: Stiffer springs prevent valve float at high RPMs, allowing for better performance.
- Retainers: Lightweight retainers reduce the overall mass, improving response and reliability.
- Adjustable Cam Gears: Allow for fine-tuning of camshaft timing, optimizing performance based on your specific setup.
Recommended Valvetrain Components
Consider these components for your RB20DET’s valvetrain upgrades:
- BC Valve Springs: Designed to handle high RPMs while providing excellent durability.
- Supertech Retainers: Lightweight and strong, perfect for high-performance applications.
- HKS Adjustable Cam Gears: Offers precise adjustments for optimal cam timing.
Additional Performance Enhancements
While camshaft and valvetrain upgrades are critical, consider these additional modifications to maximize your RB20DET’s performance:
- Turbo Upgrade: A larger turbo can provide more boost and increase overall power.
- ECU Tuning: Proper tuning ensures that the engine runs efficiently with the new modifications.
- Exhaust System: A high-flow exhaust can improve exhaust gas flow, enhancing performance.
Conclusion
Upgrading the camshaft and valvetrain of your RB20DET is a proven method to achieve significant power gains. With the right components and careful tuning, you can unlock up to 20% more power, transforming your driving experience. Always ensure that any modifications are complemented by proper tuning and supporting upgrades to maximize performance and reliability.
