The EG Civic is a beloved platform among car enthusiasts, especially those looking to enhance performance without going the forced induction route. This article will delve into various non-turbo power upgrades, specifically focusing on camshaft, intake, and exhaust modifications that can help achieve a power output between 150 and 180 horsepower.
Understanding the EG Civic Platform
The EG Civic, produced from 1992 to 1995, is known for its lightweight design and responsive handling. With a solid foundation, it offers a great opportunity for performance upgrades. Before diving into specific modifications, it’s essential to understand the engine options available and their potential.
- D15B7 – 1.5L SOHC
- D16Z6 – 1.6L DOHC VTEC
- D16Y8 – 1.6L DOHC VTEC
Camshaft Upgrades
Upgrading the camshaft is one of the most effective ways to increase horsepower in the EG Civic. A performance camshaft can optimize airflow and improve engine efficiency. Here are some popular options:
- Skunk2 Pro Series Camshaft: Known for its aggressive profile, this camshaft can significantly increase power in the higher RPM range.
- Buddy Club Spec 3 Camshaft: This cam provides a great balance of power and drivability, making it suitable for daily drivers.
- Jackson Racing Camshaft: Designed for VTEC engines, this camshaft enhances the VTEC engagement for better performance.
When selecting a camshaft, consider the following:
- Engine type (SOHC vs. DOHC)
- Intended use (daily driving vs. racing)
- Compatibility with other modifications
Intake Upgrades
A performance intake system is crucial for maximizing airflow into the engine. Upgrading the intake can help achieve better throttle response and increased horsepower. Here are some recommended options:
- AEM Cold Air Intake: This system provides a significant increase in airflow and is designed to relocate the filter outside the engine bay for cooler air.
- Injen Short Ram Intake: A great choice for those looking for a simple installation and improved throttle response.
- K&N Typhoon Intake: Offers excellent filtration and a noticeable increase in horsepower and torque.
When considering an intake upgrade, pay attention to:
- Type of intake (cold air vs. short ram)
- Material and design for heat resistance
- Filter maintenance requirements
Exhaust Upgrades
An aftermarket exhaust system can significantly enhance engine performance by improving exhaust flow. Here are some popular exhaust upgrades for the EG Civic:
- Greddy SP Exhaust: Known for its deep tone, this exhaust system offers excellent performance gains without excessive noise.
- HKS Hi-Power Exhaust: This system is lightweight and provides a noticeable increase in horsepower while maintaining a reasonable sound level.
- MagnaFlow Cat-Back Exhaust: Offers a balance of performance and sound, making it a popular choice among enthusiasts.
When upgrading the exhaust system, consider the following:
- Material (stainless steel vs. mild steel)
- Type of muffler for sound preference
- Compatibility with existing exhaust components
Combining Upgrades for Optimal Performance
To achieve the desired horsepower range of 150-180 HP, it is essential to combine these upgrades effectively. A well-matched camshaft, intake, and exhaust system will work together to optimize engine performance. Here are some tips for combining upgrades:
- Choose components designed to work together (e.g., camshaft and intake).
- Consider tuning options like a standalone ECU or reflash to maximize gains.
- Invest in supporting modifications such as a high-performance fuel pump and injectors if necessary.
Conclusion
The EG Civic is a versatile platform that can benefit greatly from non-turbo power upgrades. By focusing on camshaft, intake, and exhaust modifications, enthusiasts can achieve significant performance gains while maintaining reliability. With careful selection and combination of parts, reaching the 150-180 horsepower range is an attainable goal for any EG Civic owner.
