The Nissan Skyline R32 is a classic performance sports car that has gained worldwide popularity. With the rise of electric vehicle conversion trends, more and more R32 owners are exploring how to transform this gasoline legend into a high-performance electric vehicle. This guide will comprehensively explain how to select the most suitable electric motor for R32 EV conversions, covering key aspects such as performance matching, installation integration, and cost control.
The R32, with its lightweight chassis, excellent front-to-rear weight distribution, and rear-wheel-drive layout, serves as an ideal platform for electric conversion. However, choosing the right motor is crucial, as it must preserve the car's original handling characteristics while fully leveraging the advantages of electric drive systems.
Understanding Core Requirements for R32 EV Conversion Motors
When selecting a motor, it's essential to comprehensively consider performance goals, installation compatibility, and system matching. The original R32 came equipped with various engines ranging from the RB20E to the legendary RB26DETT, producing approximately 155 to 280 horsepower.
Key Performance Goals for R32 Electric Motors
- Power Output: 200-450 HP (approximately 150-335 kW), balancing street and track performance
- Torque: 300-650 Nm, ensuring rapid acceleration experience
- RPM Range: 0-10,000 RPM, providing a wide efficient operating range
- Weight: Preferably below 90 kg to maintain body balance
- Efficiency: Above 92%, optimizing range and energy efficiency
Layout Considerations for Motor Installation
The R32 engine bay was originally designed for the RB series inline-six engine, so motor placement requires careful planning. Most successful cases position the motor in the original engine location, using custom brackets connected to the original mounting points to maintain vehicle center of gravity and weight distribution ratio.

Installation Process and Key Considerations
Preparation and Planning
Before construction, remove the original engine, transmission, fuel, and exhaust systems. Depending on motor and battery layout, local reinforcement or openings in the chassis may be required. It's recommended to create 3D models or physical templates in advance to ensure spatial compatibility of all systems.
Motor Mounting and Bracket Fabrication
Brackets must withstand the motor's high torque output and ensure alignment with the drivetrain. Custom brackets made from steel plate or CNC-machined aluminum are commonly used, fixed through original mounting points, with consideration for vibration and noise isolation.
Drivetrain Integration Solutions
- Retain Original Transmission: Can utilize multiple gears, suitable for users pursuing traditional shifting feel and high-speed efficiency.
- Single-Speed Reducer Direct Drive: Simplified structure, reduced weight, more direct torque response, suitable for conversions seeking smoothness and low maintenance.
Professional Recommendation
When selecting a motor, consider not only peak power but also torque curve characteristics, cooling requirements, and compatibility with your chosen controller. Motors with wider efficiency ranges will provide better real-world performance and range.
Cost Analysis and Budget Planning
Main Component Cost Estimates (USD)
| Component | Economy Option | High-Performance Option |
|---|---|---|
| Electric Motor | $3,500 - $6,500 | $8,500 - $16,500 |
