The Honda EF Civic, produced between 1988 and 1991, is a beloved model among car enthusiasts for its lightweight design and tunable engine. One of the key areas to enhance the performance and reliability of the EF Civic is through camshaft and valvetrain upgrades. In this article, we will explore the best performance camshafts and valvetrain modifications that can help you achieve greater power and reliability in your EF Civic.
Understanding Camshafts and Valvetrain
The camshaft plays a crucial role in controlling the timing and duration of the engine’s valve openings. Upgrading the camshaft can lead to improved airflow and increased power output. The valvetrain, which includes components such as valves, springs, and retainers, is equally important for ensuring that the engine operates smoothly at higher RPMs.
Benefits of Upgrading Camshafts
Upgrading the camshaft in your EF Civic can yield several benefits, including:
- Increased Horsepower: Performance camshafts are designed to optimize airflow, resulting in higher horsepower.
- Better Torque Delivery: Upgraded camshafts can improve torque characteristics, making the car feel more responsive.
- Enhanced Engine Sound: A performance camshaft can give your engine a more aggressive sound, enhancing the driving experience.
Top Performance Camshafts for EF Civic
- Skunk2 Megapower Camshaft: Known for its excellent performance and reliability, this camshaft offers a great balance between power and drivability.
- Brian Crower Stage 2 Camshaft: This camshaft is designed for those looking to maximize performance without sacrificing too much low-end torque.
- Comp Cams Stage 1 Camshaft: A great option for street-driven EF Civics, providing a noticeable power increase while maintaining smooth operation.
Valvetrain Upgrades for Reliability
In addition to camshaft upgrades, enhancing the valvetrain is essential for ensuring that your engine can handle increased performance. Here are some recommended valvetrain upgrades:
- High-Performance Valve Springs: Upgrading to stiffer valve springs can prevent valve float at higher RPMs, maintaining performance and reliability.
- Retainers: Lightweight titanium or aluminum retainers can reduce overall valvetrain weight, allowing for quicker response times.
- Adjustable Cam Gears: These allow for fine-tuning of camshaft timing, optimizing performance for specific driving conditions.
Installation Tips for Camshaft and Valvetrain Upgrades
Installing a new camshaft and upgrading the valvetrain requires careful attention to detail. Here are some tips to ensure a successful installation:
- Follow Manufacturer Instructions: Always refer to the specific installation guide provided by the camshaft and valvetrain component manufacturers.
- Use Quality Gaskets: Replace gaskets during installation to avoid leaks and ensure a proper seal.
- Check Clearances: Verify that all components have the appropriate clearances to prevent interference.
Conclusion
Upgrading the camshaft and valvetrain in your EF Civic can significantly enhance both performance and reliability. By choosing the right components and following proper installation procedures, you can unlock the full potential of your vehicle. Whether you’re a daily driver or a track enthusiast, these upgrades will help you enjoy a more powerful and responsive driving experience.
