The Subaru WRX has long been a favorite among car enthusiasts, particularly those seeking to enhance performance. With the right modifications, it’s possible to push the boundaries of power and achieve over 350 horsepower. In this article, we will explore various power modifications ranging from cold air intakes to turbo upgrades that can help you reach that goal.
Understanding Power Modifications
Power modifications enhance the performance of your WRX by improving airflow, increasing fuel delivery, and optimizing engine output. These upgrades not only boost horsepower but also improve throttle response and overall driving experience.
Cold Air Intakes
A cold air intake (CAI) is one of the simplest and most effective modifications you can make to your WRX. By allowing cooler air into the engine, a CAI can improve combustion efficiency and increase power output.
- Benefits of Cold Air Intakes:
- Improved airflow and engine efficiency
- Enhanced throttle response
- Potential increase in horsepower and torque
- Popular Cold Air Intake Options:
- K&N 69 Series Typhoon
- AEM Cold Air Intake
- Injen SP Series
Upgraded Turbochargers
Upgrading the turbocharger is a significant step towards achieving over 350 horsepower. A larger turbo can provide more boost, leading to increased power across the RPM range.
- Benefits of Upgraded Turbochargers:
- Higher boost levels for increased power
- Improved torque delivery
- Potential for better fuel efficiency at higher power levels
- Popular Turbo Options:
- Garrett GTX3076R
- Blouch 1.5XTR
- FP Green Turbo
Intercooler Upgrades
An upgraded intercooler is essential when increasing turbo output. It helps maintain lower intake temperatures, which is crucial for performance and engine longevity.
- Benefits of Upgraded Intercoolers:
- Better cooling efficiency
- Reduced risk of knock
- Improved power consistency
- Popular Intercooler Options:
- Process West Verticooler
- Grimmspeed Top Mount Intercooler
- ETS Front Mount Intercooler
Exhaust System Upgrades
A high-performance exhaust system can significantly improve exhaust flow, which is critical when trying to maximize horsepower. Upgrading to a cat-back exhaust system can also enhance the sound of your WRX.
- Benefits of Exhaust System Upgrades:
- Improved exhaust flow and reduced back pressure
- Enhanced engine sound
- Potential increases in horsepower and torque
- Popular Exhaust System Options:
- Remark Cat-Back Exhaust
- Invidia Q300 Exhaust
- HKS Hi-Power Exhaust
ECU Tuning
After making significant hardware upgrades, ECU tuning is essential to maximize the performance of your WRX. A proper tune can adjust fuel maps, ignition timing, and boost levels to ensure the engine runs efficiently and safely.
- Benefits of ECU Tuning:
- Optimized performance for new modifications
- Improved throttle response
- Better fuel economy under load
- Popular Tuning Options:
- Accessport by Cobb Tuning
- ECUtek Tuning Software
- Open Source Tuning
Conclusion
Achieving over 350 horsepower in your Subaru WRX is an exciting endeavor that requires careful planning and execution. By implementing a combination of cold air intakes, turbo upgrades, intercoolers, exhaust systems, and ECU tuning, you can elevate your WRX to new performance heights. Always ensure that modifications are done with quality parts and consider professional installation for the best results.
