The Toyota MR2 electric power steering pump is a popular choice among automotive enthusiasts, particularly those involved in motorsports like drifting and road racing. This guide aims to provide detailed information about the pump, its installation, benefits, and technical specifications.

Overview of the Toyota MR2 Electric Power Steering Pump

The electric power steering (EPS) pump from the Toyota MR2 is designed to replace traditional hydraulic systems, offering several advantages. It is particularly beneficial for those looking to reduce engine load and improve steering responsiveness.

The pump operates by using an electric motor to drive a hydraulic pump, which generates the necessary pressure for steering assistance. This system allows for consistent pressure and provides a steering feel that closely resembles hydraulic setups.

Benefits of Using the MR2 Electric Power Steering Pump

  • Reduced Engine Load: The electric pump operates independently of the engine, leading to less horsepower drain compared to conventional hydraulic pumps.

  • Adjustable Pressure: The pump features an adjustment screw that allows users to modify the output pressure, ensuring compatibility with various steering systems.

  • Reliability: Proven reliability in both drifting and road racing applications makes it a favorite among performance enthusiasts.

Installation Requirements

When installing the Toyota MR2 electric power steering pump, several components are necessary:

  • Pump Assembly: A good used or new MR2 pump.
  • Hydraulic Lines: High-pressure and low-pressure lines with appropriate fittings (e.g., Dash -6 and Dash -8).
  • Mounting Bracket: A fabricated bracket to secure the pump in place.
  • Fluid Reservoir: A remote power steering fluid reservoir is required; existing OEM reservoirs can often be reused.
  • Electrical Wiring: Heavy-duty wiring (8 gauge recommended) and a high current relay or circuit breaker are essential for safe operation.

Technical Specifications

The MR2 electric power steering pump has impressive specifications that enhance its performance:
