The RB20DET engine, known for its robust design and tuning potential, has become a favorite among performance enthusiasts. One of the most effective ways to unlock additional horsepower is through camshaft upgrades. In this article, we will explore the various stages of camshaft upgrades for the RB20DET, detailing the performance gains from Stage 1 to Stage 3.
Understanding Camshaft Upgrades
Camshaft upgrades are essential for improving engine performance. The camshaft controls the timing and duration of the engine’s intake and exhaust valves. By upgrading the camshaft, you can increase airflow, enhance engine efficiency, and ultimately boost horsepower.
Stage 1 Camshaft Upgrade
The Stage 1 camshaft upgrade is an excellent starting point for those looking to enhance their RB20DET’s performance without extensive modifications. This upgrade typically features a mild increase in lift and duration compared to the stock camshaft.
- Lift: Increased lift allows for better airflow into the engine.
- Duration: A longer duration helps keep the valves open longer, improving exhaust flow.
- Power Gains: Expect around 20-30 additional horsepower with proper tuning.
Benefits of Stage 1 Upgrade
The Stage 1 upgrade is ideal for daily drivers who want a noticeable boost in performance without sacrificing reliability. Key benefits include:
- Improved throttle response.
- Enhanced mid-range torque.
- Compatibility with stock ECU settings with minor tuning adjustments.
Stage 2 Camshaft Upgrade
The Stage 2 camshaft upgrade is designed for those who are looking for more significant performance improvements. This upgrade typically features increased lift and duration compared to the Stage 1 camshaft, making it suitable for higher RPM applications.
- Lift: Further increased lift enhances airflow even more.
- Duration: Extended duration allows for better exhaust scavenging.
- Power Gains: Expect gains of 40-60 horsepower with the right supporting modifications.
Benefits of Stage 2 Upgrade
The Stage 2 camshaft upgrade is perfect for enthusiasts looking to push their RB20DET further. Benefits include:
- Significantly increased peak power.
- Improved high RPM performance.
- Better compatibility with upgraded turbochargers and exhaust systems.
Stage 3 Camshaft Upgrade
The Stage 3 camshaft upgrade is the ultimate choice for serious racers and performance enthusiasts. This camshaft offers maximum lift and duration, designed for high-performance applications.
- Lift: Maximum lift for optimal airflow.
- Duration: Extended duration for maximum exhaust efficiency.
- Power Gains: Achieve over 100 horsepower gains with proper tuning and supporting mods.
Benefits of Stage 3 Upgrade
The Stage 3 upgrade is designed for those who want to extract every last bit of performance from their RB20DET. Key benefits include:
- Exceptional peak horsepower and torque.
- Enhanced performance at high RPMs.
- Requires supporting modifications, such as upgraded fuel systems and ECU tuning.
Choosing the Right Upgrade
When selecting a camshaft upgrade for your RB20DET, consider your performance goals and the modifications you have or plan to make. Each stage offers unique benefits and power gains, so choose one that aligns with your overall performance strategy.
Supporting Modifications
To maximize the benefits of your camshaft upgrade, consider the following supporting modifications:
- Upgraded turbocharger for increased boost.
- Performance exhaust system to reduce back pressure.
- Upgraded fuel injectors to meet increased fuel demands.
- ECU tuning to optimize engine performance.
Conclusion
Upgrading the camshaft on your RB20DET can lead to significant horsepower gains and improved performance. Whether you choose Stage 1 for daily driving, Stage 2 for enhanced performance, or Stage 3 for maximum power, each upgrade offers unique benefits. Ensure you pair your camshaft upgrade with the right supporting modifications for the best results.
