The Honda Civic Si has long been a favorite among car enthusiasts for its balance of performance, reliability, and everyday usability. For those looking to push the power envelope, building a 350 horsepower Civic Si is an exciting project. In this article, we will explore turbo kit recommendations and supporting modifications that can help you achieve that power while maintaining daily drivability.
Understanding the Honda Civic Si Platform
The Honda Civic Si is built on a solid platform that offers a good balance of weight, handling, and power. The 2017-2021 models, powered by a turbocharged 2.0L inline-four engine, provide a great foundation for tuning. With the right modifications, these vehicles can easily handle increased power while remaining reliable for daily driving.
Choosing the Right Turbo Kit
To reach the 350 hp goal, selecting an appropriate turbo kit is crucial. Here are some recommended kits that have proven effective for the Honda Civic Si:
- Hondata FlashPro: This is a tuning solution that allows you to optimize your Civic Si’s performance after installing a turbo kit.
- Greddy Turbo Kit: Known for its quality and performance, this kit provides a significant power increase and comes with all necessary components.
- Kraftwerks Supercharger Kit: While technically a supercharger, this kit offers a unique boost in power and is a reliable option for daily drivers.
- HKS Turbo Kit: HKS is a reputable brand that offers a complete turbo kit designed for the Civic Si, known for its durability and performance.
Supporting Modifications for Reliability
While a turbo kit is essential for achieving your power goals, supporting modifications are necessary to ensure reliability and longevity. Here are some key components to consider:
- Upgraded Fuel System: A high-flow fuel pump and larger fuel injectors are essential to provide the necessary fuel for increased horsepower.
- Aftermarket Exhaust System: A performance exhaust will help reduce back pressure and improve airflow, enhancing turbo performance.
- Intercooler Upgrade: An upgraded intercooler helps keep intake temperatures low, which is crucial for performance and reliability.
- Engine Management: A proper tuning solution, such as Hondata or KTuner, is vital for optimizing engine performance and safety.
Suspension and Handling Upgrades
With increased power comes the need for better handling. Upgrading your suspension will improve your Civic Si’s performance on the road and track. Consider the following modifications:
- Coilovers: Adjustable coilovers allow you to fine-tune your ride height and damping for improved handling.
- Upgraded Sway Bars: Stiffer sway bars reduce body roll and enhance cornering performance.
- Performance Tires: Investing in high-quality tires will provide better grip and handling characteristics.
- Strut Braces: Adding strut braces can improve chassis rigidity, enhancing overall handling.
Braking System Enhancements
As you increase power, it’s essential to ensure your braking system can handle the added performance. Consider these upgrades:
- Performance Brake Pads: Upgrading to high-performance brake pads will improve stopping power and reduce brake fade.
- Slotted or Drilled Rotors: These rotors improve heat dissipation and provide better braking performance.
- Stainless Steel Brake Lines: Upgrading to stainless steel lines improves brake feel and responsiveness.
- Big Brake Kit: For serious performance enthusiasts, a big brake kit provides superior stopping power and heat management.
Conclusion
Building a 350 hp Honda Civic Si is an exciting journey that requires careful planning and execution. By selecting the right turbo kit and supporting modifications, you can achieve impressive power while maintaining the reliability needed for daily driving. Remember to focus on the entire system, including suspension, brakes, and engine management, to create a well-rounded performance vehicle. With the right approach, your Civic Si can become a powerful and enjoyable car for everyday use.
