Best Size and Brand Choices for WRX Turbo Upgrades: From 600 HP to 700+ HP Builds

The Subaru WRX has long been a favorite among car enthusiasts, particularly for those seeking performance upgrades. When it comes to turbocharging, selecting the right size and brand is crucial for achieving the desired horsepower, especially when aiming for builds in the range of 600 to 700+ hp. This article will explore the best turbo options, brands, and considerations for WRX enthusiasts looking to maximize their vehicle’s performance.

Understanding Turbocharger Sizing

Turbocharger sizing is critical in determining how much power your WRX can produce. A turbo that is too small may restrict airflow, while one that is too large can lead to turbo lag. Here are key factors to consider:

  • Compressor Size: A larger compressor can move more air, increasing potential horsepower.
  • Turbine Size: The turbine size affects exhaust flow and response time.
  • AR Ratio: The aspect ratio (AR) of the turbine housing influences spool time and power delivery.

Choosing the Right Turbo for 600 HP Builds

For builds aiming for 600 hp, a balance between spool time and peak power is essential. Here are some recommended turbos:

  • Garrett GTX3076R: Known for its quick spool and high efficiency, this turbo is ideal for street and track use.
  • Blouch 2.5XT-R: Offers excellent power delivery with a focus on reliability and performance.
  • FP Black: A favorite among WRX enthusiasts for its ability to produce strong power without sacrificing response.

Considerations for 600 HP Builds

When selecting a turbo for a 600 hp build, keep the following in mind:

  • Fuel System: Ensure your fuel system can support the increased demand.
  • ECU Tuning: Proper tuning is essential for maximizing performance and reliability.
  • Supporting Mods: Upgraded intercoolers, exhaust systems, and intake systems are necessary for optimal performance.

Turbo Options for 700+ HP Builds

For builds exceeding 700 hp, the turbo must be capable of handling higher airflow and exhaust flow. Here are some top choices:

  • Garrett GTX3582R: This turbo is capable of producing massive power while maintaining a reasonable spool time.
  • Blouch Dominator 1.5: Known for its high horsepower capabilities and solid performance across the RPM range.
  • FP Green: A versatile option that can support high power levels while providing good response.

Key Considerations for 700+ HP Builds

When pursuing a 700+ hp build, consider the following:

  • Engine Internals: Upgraded pistons, rods, and bearings are crucial for handling increased power and stress.
  • Cooling Systems: Enhanced cooling solutions, including larger radiators and oil coolers, are vital for engine longevity.
  • Transmission Upgrades: Ensure your transmission can handle increased power to avoid premature failure.

Top Brands for WRX Turbo Upgrades

Choosing a reputable brand can make a significant difference in performance and reliability. Here are some top brands to consider:

  • Garrett: Renowned for their high-performance turbos and innovative technology.
  • Blouch: Offers a variety of turbo options tailored specifically for Subaru applications.
  • Forced Performance: Known for their quality and performance, FP turbos are a popular choice among enthusiasts.

Conclusion

Upgrading the turbo on your WRX can significantly enhance performance, especially when targeting builds of 600 to 700+ hp. By understanding turbo sizing, selecting the right options, and considering the necessary supporting modifications, you can achieve your desired horsepower goals. Whether you choose Garrett, Blouch, or Forced Performance, investing in a quality turbo will ensure your WRX performs at its best.
