The Subaru WRX is a beloved performance vehicle that has captured the hearts of enthusiasts around the world. With its turbocharged engine and all-wheel drive, it offers a thrilling driving experience. However, many owners seek to push their WRX’s performance beyond the factory settings. Here are the top 10 power mods that can help boost your Subaru WRX performance from 300 to 400+ horsepower.
1. Performance Tune
One of the most effective ways to increase horsepower is through a performance tune. By recalibrating the engine’s ECU, you can unlock additional power and improve throttle response.
2. Upgraded Turbocharger
Upgrading to a larger turbocharger can significantly increase airflow and boost pressure, resulting in more horsepower. Consider options like the Garret GTX series for optimal performance.
3. High-Performance Intercooler
A high-performance intercooler helps reduce intake temperatures, allowing for denser air and more power. Look for brands like Mishimoto or Cobb for reliable options.
4. Cat-Back Exhaust System
A cat-back exhaust system improves exhaust flow, reducing back pressure and increasing horsepower. Brands like Borla and Invidia offer great sound and performance enhancements.
5. Cold Air Intake
Installing a cold air intake system allows your engine to breathe better by drawing in cooler air. This can lead to improved power and efficiency. K&N and AEM are popular choices.
6. Upgraded Fuel Injectors
To support higher horsepower levels, upgrading to larger fuel injectors is essential. This ensures your engine receives the necessary fuel to match the increased airflow from other mods.
7. High-Performance Fuel Pump
A high-performance fuel pump is crucial for delivering the right amount of fuel under higher boost levels. Consider options like the Walbro 255 or DeatschWerks for reliability.
8. Upgraded Engine Internals
If you’re looking to push your WRX beyond 400 horsepower, consider upgrading engine internals like pistons and rods. Forged components can handle the increased stress and heat.
9. Performance Clutch
With increased power comes the need for a stronger clutch. A performance clutch can handle the extra torque and provide a more engaging driving experience.
10. Suspension Upgrades
While not directly related to horsepower, upgrading your suspension can enhance handling and stability, making it easier to put your new power to the ground. Consider coilovers or sway bars for better performance.
Conclusion
Boosting your Subaru WRX’s performance from 300 to 400+ horsepower is achievable with the right modifications. By investing in these top 10 power mods, you can enjoy an exhilarating driving experience while ensuring your WRX stands out on the road.
