The Subaru BRZ FA20 engine is known for its balanced performance and driving experience. However, many enthusiasts seek to enhance its capabilities through various upgrades. This article provides a detailed cost analysis of upgrading the BRZ FA20 engine, focusing on the transition from intake modifications to forced induction systems.
Understanding the BRZ FA20 Engine
The FA20 engine is a 2.0-liter flat-four engine that powers the Subaru BRZ and Toyota 86. It features a naturally aspirated design, which is appreciated for its lightweight and low center of gravity. However, to achieve higher power outputs, many owners consider various upgrades.
Intake Modifications
Upgrading the intake system is one of the first steps many enthusiasts take to improve engine performance. A better intake allows for increased airflow, leading to improved combustion efficiency.
- Cold Air Intake System: $300 – $600
- Short Ram Intake: $250 – $500
- High-Performance Air Filter: $50 – $100
Cost Breakdown
When selecting an intake system, it’s essential to consider both the initial cost and the potential performance gains. A cold air intake typically provides the best performance increase, while a short ram intake is easier to install.
Exhaust Upgrades
After the intake, upgrading the exhaust system can further enhance engine performance. A free-flowing exhaust reduces back pressure and allows the engine to breathe better.
- Cat-Back Exhaust System: $500 – $1,200
- Header Upgrade: $600 – $1,000
- High-Flow Catalytic Converter: $300 – $700
Cost Analysis
Investing in an exhaust upgrade can yield significant performance improvements, especially when combined with an intake upgrade. The total cost for both upgrades can range from $1,200 to $2,500, depending on the choices made.
Tuning the Engine
After completing intake and exhaust upgrades, tuning the engine is crucial to maximize performance gains. Tuning adjusts the engine’s parameters to accommodate the new modifications.
- ECU Tune: $400 – $800
- Dyno Tuning: $300 – $600
Investment Considerations
Tuning is a necessary step after modifications, as it ensures the engine runs efficiently and reliably. The combined cost for tuning can range from $700 to $1,400, depending on the complexity of the tune and the tuning shop.
Forced Induction Upgrades
For those seeking significant power increases, forced induction is a popular choice. This includes superchargers and turbochargers, which can dramatically enhance engine output.
- Turbocharger Kit: $3,000 – $7,000
- Supercharger Kit: $4,000 – $8,000
- Intercooler Upgrade: $500 – $1,500
Cost Implications
Forced induction systems come with a higher price tag but offer substantial power gains. The total investment for a complete forced induction setup can range from $4,000 to over $10,000, depending on the components chosen and installation costs.
Conclusion
Upgrading the BRZ FA20 engine offers various paths, from simple intake modifications to full forced induction systems. Each step presents its own costs and benefits, allowing enthusiasts to tailor their upgrades based on performance goals and budget. Understanding these costs is crucial for making informed decisions about enhancing the BRZ’s performance.
