Converting a Honda Civic to electric power steering (EPS) is an increasingly popular upgrade among car enthusiasts, EV converters, and workshop owners. Whether you are restoring an older Civic, performing an engine swap, or building a full electric vehicle, an Electric Power Steering conversion offers clear advantages in efficiency, simplicity, and driving comfort. In this article, we’ll explore what a Honda Civic Electric Power Steering Conversion is, why it makes sense, how it works, and what to consider before starting the project.
What Is Electric Power Steering (EPS)?
Electric Power Steering replaces the traditional hydraulic power steering system—pump, belts, hoses, and fluid—with an electric motor and control unit that assists steering only when needed. Instead of drawing power constantly from the engine, EPS uses electrical energy on demand, improving efficiency and reducing mechanical complexity.
For Honda Civic models, especially older generations (EG, EK, EF, and early FD), EPS conversion is a practical modernization that aligns well with today’s electrification trends.
Why Convert a Honda Civic to Electric Power Steering?
1. Improved Energy Efficiency
Hydraulic power steering systems rely on an engine-driven pump that consumes power continuously. EPS, on the other hand, only draws energy when steering input is applied. This is especially important for:
- Electric vehicle (EV) conversions
- Hybrid builds
- Fuel-efficiency-focused projects
Removing the hydraulic pump reduces parasitic losses and improves overall system efficiency.
2. Simplified Mechanical Layout
An EPS conversion eliminates:
- Power steering pump
- Hydraulic hoses and reservoir
- Belts and pulleys
This results in a cleaner engine bay, fewer failure points, and easier maintenance—an advantage for both ICE and EV-converted Honda Civics.
3. Ideal for EV Conversions
For Honda Civic EV conversions, EPS is almost mandatory. Hydraulic systems are impractical without an engine-driven pump, while EPS integrates seamlessly with a high-voltage or low-voltage electrical system. Many EPS units can operate on 12V, 48V, or higher-voltage DC systems, depending on design.
4. Better Steering Feel and Customization
Modern EPS systems can be tuned. With the right controller, steering assist levels can be adjusted based on:
- Vehicle speed
- Driver preference
- Urban vs highway driving
This provides a more refined driving experience compared to older hydraulic systems.
Common EPS Conversion Options for Honda Civic
Column-Type Electric Power Steering
This is the most common solution for Honda Civic EPS conversions. A compact electric motor is installed directly on the steering column, usually under the dashboard.
Advantages:
- Compact and lightweight
- Minimal modification to the steering rack
- Lower installation cost
Column-type EPS is widely used in retrofit kits and is suitable for most Civic generations.
Rack-Type Electric Power Steering
Rack-mounted EPS replaces or modifies the steering rack itself. While it offers more direct steering feel, it requires more fabrication and space.
Best for:
- Performance builds
- High-power EV conversions
- Professional workshops
Key Components of a Honda Civic EPS Conversion Kit
A typical Electric Power Steering conversion kit includes:
- EPS motor and steering column assembly
- EPS control unit (ECU or controller)
- Torque and angle sensors
- Wiring harness
- Mounting brackets and adapters
Some advanced kits also include CAN communication support or adjustable controllers for fine-tuning assist levels.
Installation Considerations
Before starting a Honda Civic Electric Power Steering conversion, keep the following points in mind:
- Compatibility: Ensure the EPS unit matches your Civic generation and steering geometry.
- Electrical Capacity: Verify your vehicle’s electrical system can supply sufficient current, especially during low-speed steering.
- Safety: Steering is a critical system—professional installation and proper calibration are strongly recommended.
- Regulatory Compliance: In some regions, steering modifications may require inspection or certification.
Cost and Time Investment
The cost of a Honda Civic EPS conversion depends on:
- Type of EPS system (column vs rack)
- New vs refurbished components
- Custom fabrication requirements
On average, a column-type EPS conversion is more affordable and can often be completed within 1–2 working days by an experienced workshop.
Final Thoughts
A Honda Civic Electric Power Steering Conversion is a smart upgrade for drivers seeking better efficiency, cleaner design, and improved driving comfort. It is especially valuable for EV conversions, engine swaps, and classic Civic restorations where reliability and simplicity matter.
As electric mobility continues to grow, EPS conversions are no longer just an option—they are becoming a standard solution for modernizing iconic vehicles like the Honda Civic. With the right components and professional installation, EPS can significantly enhance both daily drivability and long-term vehicle value.
If you’re planning a Honda Civic project—whether electric or conventional—electric power steering is an upgrade worth serious consideration.
