The VA WRX has become a popular platform for enthusiasts looking to enhance performance. One of the most significant upgrades you can make is to the turbocharger. With the right bolt-on modifications, achieving over 400 horsepower is possible. This article will guide you through the essential upgrades and considerations for maximizing your VA WRX’s performance.
Understanding the VA WRX Turbocharger
The VA WRX, produced from 2015 onwards, features a turbocharged FA20 engine. This engine is known for its potential and responsiveness, but it can be further enhanced with a turbo upgrade. Understanding how the turbocharger works and its role in the engine’s performance is crucial for any modification.
Choosing the Right Turbocharger
When upgrading your turbocharger, selecting the right model is essential. Various options are available, each offering different performance characteristics. Here are some popular choices:
- Garrett GTX2860R: Known for its quick spool and high efficiency.
- FP Green: Offers a balance of power and reliability.
- Blouch Dominator: Provides high horsepower potential with robust construction.
Essential Bolt-On Modifications
To reach the 400+ horsepower mark, several bolt-on modifications should be considered in conjunction with your turbo upgrade. These modifications enhance airflow, fuel delivery, and overall engine performance.
Upgraded Intercooler
An aftermarket intercooler is crucial for lowering intake temperatures and increasing efficiency. Look for options with a larger core size and better flow characteristics.
High-Flow Fuel Injectors
Upgrading to high-flow fuel injectors ensures that your engine receives the necessary fuel to support the increased power. Consider injectors rated for at least 1000cc/min for optimal performance.
Fuel Pump Upgrade
A high-performance fuel pump is essential to maintain fuel pressure under increased demand. Look for pumps that can support your new power levels effectively.
Performance Exhaust System
A performance exhaust system reduces back pressure and enhances exhaust flow. This upgrade not only improves horsepower but also provides a more aggressive sound.
ECU Tuning
After installing your new turbo and supporting mods, an ECU tune is necessary to optimize performance. A professional tune will adjust fuel maps, boost levels, and ignition timing to unleash the full potential of your setup.
Installation Considerations
When upgrading your turbocharger and supporting components, installation is key. Here are some points to consider:
- Professional Installation: If you’re not experienced, consider hiring a professional to ensure everything is installed correctly.
- Quality Parts: Always use high-quality parts to prevent failures and maintain reliability.
- Follow Manufacturer Guidelines: Adhere to the specifications provided by manufacturers for each component.
Maintaining Your Upgraded VA WRX
After achieving your performance goals, maintaining your vehicle is crucial. Regular checks and maintenance will ensure longevity and reliability.
- Regular Oil Changes: Use high-quality synthetic oil and change it at recommended intervals.
- Monitor Boost Levels: Keep an eye on your boost gauge to ensure everything is functioning as it should.
- Check for Leaks: Regularly inspect for any boost leaks or exhaust leaks that may develop.
Conclusion
Upgrading the turbocharger on your VA WRX can provide exhilarating performance gains. By selecting the right components and ensuring proper installation and maintenance, achieving over 400 horsepower with bolt-ons is within reach. Embrace the journey of performance tuning and enjoy the thrill of driving your enhanced WRX.
