Top Turbochargers for Wrx Built Engines: Achieving 400-500 Hp with Precision

by

The Subaru WRX has long been a favorite among car enthusiasts and performance tuners. With its rally heritage and turbocharged engine, it offers a solid platform for building high horsepower setups. In this article, we will explore the top turbochargers for WRX built engines that can help achieve an impressive 400-500 horsepower with precision engineering.

Understanding Turbochargers

A turbocharger is a forced induction system that compresses air entering the engine, allowing for more air and fuel to be burned, which increases power output. For WRX enthusiasts looking to push their engines into the 400-500 hp range, selecting the right turbocharger is crucial. Factors such as size, efficiency, and spool time play significant roles in performance.

Top Turbochargers for WRX Built Engines

  • Garrett GTX3071R: Known for its quick spool and excellent power delivery, the GTX3071R is a popular choice among WRX tuners.
  • Blouch 20G-XT: This turbo provides a great balance of power and response, making it ideal for street and track use.
  • FP Black: Designed for high horsepower applications, the FP Black can support up to 600 hp with the right supporting mods.
  • VF48: A factory turbo upgrade that offers a significant increase in power without sacrificing reliability.
  • Garrett GTX3582R: For those looking to push beyond 500 hp, the GTX3582R is a robust option that can handle high boost levels.

Key Features to Consider

When selecting a turbocharger for your WRX, consider the following key features:

  • Compressor Size: Larger compressors can move more air but may take longer to spool.
  • Turbo Lag: Look for turbos with minimal lag for better throttle response.
  • Durability: Ensure the turbo is built to withstand high boost levels and heat.
  • Compatibility: Verify that the turbo fits your specific WRX model and year.
  • Supporting Mods: Consider the necessary supporting modifications, such as fuel pumps and intercoolers, to maximize performance.

Installation and Tuning

Installing a new turbocharger on your WRX is a significant task that requires mechanical knowledge and precision. It is recommended to follow these steps:

  • Gather Necessary Tools: Ensure you have all required tools and parts before starting the installation.
  • Remove Old Turbo: Carefully detach the existing turbocharger and associated components.
  • Install New Turbo: Follow the manufacturer’s instructions for installing the new turbocharger.
  • Check for Leaks: After installation, check all connections for leaks and ensure proper fitment.
  • Tuning: A proper tune is essential to maximize the performance of your new turbo and ensure engine safety.

Conclusion

Choosing the right turbocharger for your WRX built engine is key to achieving the desired power output of 400-500 hp. By considering factors such as turbo size, spool time, and supporting modifications, you can enhance your vehicle’s performance significantly. Whether you opt for the Garrett GTX3071R or the FP Black, proper installation and tuning will ensure that your WRX delivers the exhilarating performance you seek.
