The Honda S2000 is a beloved sports car known for its high-revving engine and exceptional handling. However, many enthusiasts seek to enhance its performance further. One of the most effective ways to achieve this is through a cams and valvetrain upgrade. In this article, I will share my personal experience with a $1,500 upgrade and the real-world results that followed.
Understanding the Cams and Valvetrain Upgrade
The valvetrain system is crucial for engine performance, controlling how air and fuel enter the combustion chamber. Upgrading the cams and valvetrain can significantly improve engine efficiency and power delivery. This upgrade typically involves replacing the camshaft, adjusting the timing, and upgrading components like springs and retainers.
The Upgrade Process
Before diving into the upgrade, I conducted extensive research to understand the best components for my S2000. After consulting with fellow enthusiasts and mechanics, I settled on a reputable camshaft brand and accompanying valvetrain components. The total cost for the parts came to around $1,500.
Choosing the Right Components
When selecting components for the upgrade, I focused on:
- High-performance camshaft designed for improved power delivery.
- Upgraded valve springs to handle the increased lift and duration.
- Strong retainers to ensure reliability at high RPMs.
Installation Process
The installation was a challenging yet rewarding experience. With the help of a friend who is a seasoned mechanic, we tackled the project over a weekend. Here’s a brief overview of the steps involved:
- Remove the engine cover and intake manifold.
- Take off the valve cover to access the valvetrain components.
- Replace the old camshaft with the new high-performance camshaft.
- Install upgraded valve springs and retainers.
- Reassemble everything and ensure proper timing alignment.
Real-World Performance Results
After completing the installation, I was eager to see how the upgrades would impact my driving experience. The results were nothing short of impressive.
Power Gains
On the dyno, my S2000 showed a significant increase in horsepower and torque. The numbers jumped from approximately 220 horsepower to 250 horsepower at the wheels, showcasing the effectiveness of the cams and valvetrain upgrade.
Improved Throttle Response
One of the most noticeable changes was the improved throttle response. The engine felt more eager to rev, and the power delivery was smoother throughout the RPM range. This transformation made driving the S2000 even more exhilarating.
Sound and Driving Experience
With the new cams, the engine produced a more aggressive sound, enhancing the overall driving experience. The car felt alive, and every drive became a thrilling adventure.
Considerations and Final Thoughts
While the upgrade brought substantial benefits, there are a few considerations to keep in mind:
- Increased fuel consumption: The enhanced performance may lead to slightly higher fuel consumption.
- Potential for increased wear: High-performance components can lead to more wear over time, so regular maintenance is essential.
- Compatibility: Ensure that the parts chosen are compatible with your specific model year of the S2000.
In conclusion, the $1,500 cams and valvetrain upgrade transformed my Honda S2000 into a more powerful and responsive machine. The investment was well worth it, and I highly recommend it to fellow enthusiasts looking to elevate their driving experience. With the right components and proper installation, you can unlock the full potential of this iconic sports car.
