by

The Toyota 86 is a beloved sports car known for its lightweight design and agile handling. To unlock its full potential, many enthusiasts turn to turbocharging, specifically the BorgWarner EFR series. This guide will help you select the right turbocharger to achieve over 600 horsepower while maintaining reliability and drivability.

Understanding Turbocharger Basics

Before diving into the selection process, it’s essential to understand how turbochargers work. A turbocharger uses exhaust gases to spin a turbine, which compresses incoming air, allowing for more air and fuel to enter the engine. This results in increased power output.

Why Choose BorgWarner EFR Series?

The BorgWarner EFR series is known for its innovative technology and performance capabilities. Key features include:

  • Compact Design: EFR turbochargers are smaller and lighter, making them easier to install and reducing lag.
  • Integrated Wastegate: This feature simplifies installation and improves response times.
  • High Efficiency: EFR turbos provide excellent power output with lower boost levels.

Factors to Consider When Selecting a Turbocharger

When choosing a turbocharger for your Toyota 86, consider the following factors:

  • Power Goals: Determine your horsepower target, which in this case is 600+ HP.
  • Engine Size: The displacement of your engine affects turbocharger selection.
  • Boost Pressure: Higher boost can lead to more power but also requires careful tuning.
  • Fuel Type: Consider whether you will use pump gas or race fuel, as this impacts tuning and reliability.

For achieving 600+ HP on your Toyota 86, the following BorgWarner EFR turbochargers are recommended:

  • BorgWarner EFR 7670: Ideal for quick spool and excellent mid-range power.
  • BorgWarner EFR 8374: Offers a balance between high-end power and response, suitable for higher horsepower builds.
  • BorgWarner EFR 9180: Best for maximum power, capable of supporting over 700 HP with proper supporting mods.

Supporting Modifications

To achieve and sustain 600+ HP, consider these supporting modifications:

  • Upgraded Fuel System: Larger injectors and a high-flow fuel pump are essential.
  • Intercooler Upgrade: A larger intercooler helps manage intake temperatures.
  • Exhaust System: A free-flowing exhaust system reduces backpressure and enhances turbo performance.
  • ECU Tuning: Proper tuning is crucial to maximize performance and ensure reliability.

Tuning for Performance

Tuning is a critical step in achieving your power goals. Work with a reputable tuner who has experience with turbocharged setups on the Toyota 86. They will help you optimize fuel maps, ignition timing, and boost levels for maximum performance.

Conclusion

Choosing the right BorgWarner EFR turbocharger for your Toyota 86 can significantly enhance its performance. By considering your power goals, supporting modifications, and proper tuning, you can achieve over 600 HP while maintaining reliability and drivability. Embrace the thrill of turbocharging and elevate your driving experience!
