The F20C engine, known for its high-revving nature and impressive performance, is a favorite among Honda enthusiasts. One of the most effective modifications to enhance its power output is the camshaft swap. This article delves into how a camshaft swap can add 15-20 horsepower to the F20C engine and provides essential installation tips for a successful upgrade.
Understanding the F20C Engine
The F20C is a 2.0-liter inline-four engine that powers the Honda S2000. It is renowned for its high specific output, achieving around 240 horsepower at 8,300 RPM. The engine’s design features a DOHC layout and VTEC technology, which enhances performance at high RPMs. However, even with its impressive stock performance, many enthusiasts seek to push the limits further.
Benefits of a Camshaft Swap
Swapping the camshaft in the F20C engine can yield significant performance gains. Here are some benefits of upgrading the camshaft:
- Increased Horsepower: A camshaft swap can add 15-20 horsepower, depending on the specific cam profile chosen.
- Better Torque Curve: A performance camshaft can improve the torque delivery across the RPM range.
- Enhanced Engine Sound: Upgraded camshafts can provide a more aggressive engine sound, enhancing the driving experience.
- Improved Throttle Response: A new camshaft can lead to quicker throttle response, making the car feel more lively.
Choosing the Right Camshaft
When selecting a camshaft for the F20C, consider the following factors:
- Cam Profile: Different profiles offer various performance characteristics. Choose one that matches your driving style.
- Lift and Duration: Higher lift and longer duration can increase power but may affect idle quality and drivability.
- Compatibility: Ensure the camshaft is compatible with your engine’s VTEC system.
- Brand Reputation: Opt for reputable brands known for quality and performance.
Installation Tips
Installing a new camshaft in the F20C engine requires careful attention to detail. Here are some tips to ensure a successful installation:
- Gather Necessary Tools: Ensure you have all required tools, including a torque wrench, camshaft holder, and timing tools.
- Follow Service Manual: Always refer to the factory service manual for specific torque settings and procedures.
- Check Timing: Properly align the camshaft timing with the crankshaft to avoid engine damage.
- Inspect Components: While the engine is apart, inspect other components such as the timing belt and seals for wear.
- Use Quality Lubricants: Apply assembly lube to the camshaft and bearings during installation to ensure proper lubrication upon startup.
Post-Installation Considerations
After installing the new camshaft, there are several considerations to keep in mind:
- Break-In Period: Follow the manufacturer’s recommendations for breaking in the new camshaft to ensure longevity.
- ECU Tuning: Consider reprogramming the ECU to optimize performance with the new camshaft.
- Monitor Engine Performance: Keep an eye on engine performance and listen for any unusual noises.
- Regular Maintenance: Maintain regular oil changes and inspections to keep the engine running smoothly.
Conclusion
The F20C camshaft swap is a powerful modification that can significantly enhance engine performance, adding 15-20 horsepower. By selecting the right camshaft and following proper installation procedures, enthusiasts can enjoy improved throttle response and an exhilarating driving experience. Always remember to consider post-installation factors to ensure the longevity and reliability of your engine.
