The Subaru WRX has long been celebrated for its performance and tuning potential, particularly when it comes to upgrades that enhance power and reduce turbo lag. In this article, we will explore the best intercooler and turbo upgrades for a WRX built engine, aiming to maximize power and minimize turbo lag.
Understanding Intercoolers
Intercoolers play a crucial role in the performance of turbocharged engines. They cool the air compressed by the turbocharger before it enters the engine, which helps improve efficiency and power output.
Types of Intercoolers
- Front-Mount Intercoolers: These are larger and provide better cooling efficiency by positioning the intercooler at the front of the vehicle.
- Top-Mount Intercoolers: Often found in stock WRXs, these are compact and easier to install, but may not cool as effectively as front-mount options.
Top Intercooler Upgrades for WRX
When considering intercooler upgrades for your WRX, several high-performance options stand out:
- Process West Verticooler: Known for its excellent cooling efficiency and reduced pressure drop, this front-mount intercooler is a favorite among enthusiasts.
- GrimmSpeed Top Mount Intercooler: This upgrade offers a perfect balance of performance and ease of installation, making it ideal for daily drivers.
- COBB Tuning Front Mount Intercooler: With a large core and efficient design, this intercooler maximizes airflow and cooling capacity.
The Role of Turbochargers
Turbochargers are essential for increasing the power output of an engine. They compress the intake air, allowing more air and fuel to enter the combustion chamber, resulting in higher power levels.
Choosing the Right Turbocharger
Selecting the right turbocharger can significantly impact your WRX’s performance. Key factors to consider include:
- Size: Larger turbos can produce more power but may introduce lag.
- Type: Ball bearing turbos offer quicker spool times compared to journal bearing turbos.
- Compatibility: Ensure the turbo is compatible with your specific WRX model and engine setup.
Top Turbo Upgrades for WRX
Here are some of the best turbo upgrades available for the WRX:
- Garrett GTX3071R: This turbo provides an excellent balance of power and responsiveness, making it a popular choice for built engines.
- Blouch 1.5XTR: Known for its reliability and power potential, this turbo is ideal for those looking to push their WRX to the limits.
- FP Black: This turbo is designed for high horsepower applications and offers minimal turbo lag, making it a favorite among racers.
Maximizing Performance with Supporting Mods
To truly maximize the performance of your WRX built engine, consider the following supporting modifications:
- Upgraded Fuel System: Ensure your fuel injectors and pump can support the increased power levels.
- ECU Tuning: A proper tune is essential to optimize your engine’s performance and ensure reliability.
- Exhaust Upgrades: A high-flow exhaust system can improve turbo spool and overall power output.
Conclusion
Upgrading the intercooler and turbocharger on your WRX built engine is a surefire way to maximize power and minimize turbo lag. By carefully selecting high-quality components and considering supporting modifications, you can unleash the full potential of your Subaru WRX.
