Fa20 Power Gains: Comparing Turbo Vsnaturally Aspirated Upgrades

by

The FA20 engine, known for its balance of performance and efficiency, has garnered attention from car enthusiasts looking to enhance power output. This article delves into the differences between turbocharging and naturally aspirated upgrades, helping you make an informed decision for your vehicle.

Understanding the FA20 Engine

The FA20 engine is a flat-four, boxer engine produced by Subaru. With its compact design and low center of gravity, it offers unique handling characteristics. This engine is commonly found in models such as the Subaru BRZ and Toyota 86, making it a popular choice for modifications.

Turbocharging the FA20

Turbocharging involves the use of a turbine-driven forced induction system to increase the engine’s air intake, resulting in higher power output. Here are some key benefits of turbocharging the FA20:

  • Increased Power: Turbochargers can significantly boost horsepower and torque, often doubling the engine’s output.
  • Improved Efficiency: By utilizing exhaust gases, turbochargers can enhance fuel efficiency at higher speeds.
  • Versatility: Turbo kits can be tailored to suit various performance goals, from mild to extreme upgrades.

Several aftermarket companies offer turbo kits specifically designed for the FA20 engine. Some of the most popular options include:

  • GrimmSpeed Turbo Kit
  • Blouch Turbo
  • FP Black Turbo Kit

Naturally Aspirated Upgrades

Naturally aspirated upgrades focus on enhancing the engine’s inherent performance without forced induction. This approach often involves modifications to the intake, exhaust, and engine management systems. Key benefits include:

  • Linear Power Delivery: Naturally aspirated engines provide a smooth power curve, making them predictable and enjoyable to drive.
  • Less Complexity: Without the need for a turbocharger, naturally aspirated setups can be simpler and more reliable.
  • Weight Savings: Many NA upgrades are lighter than turbo systems, contributing to better handling.

Common Naturally Aspirated Upgrades for FA20

For those looking to enhance their FA20’s performance naturally, consider these upgrades:

  • High-Performance Intake Manifold
  • Upgraded Exhaust System
  • ECU Tune

Comparative Analysis: Turbo vs. Naturally Aspirated

When choosing between turbocharging and naturally aspirated upgrades, it’s essential to weigh the pros and cons of each approach. Below is a comparative analysis:

  • Power Output: Turbo systems generally provide a more significant power increase compared to naturally aspirated upgrades.
  • Driveability: Naturally aspirated engines often offer a more linear and predictable power band.
  • Cost: Turbo kits can be more expensive upfront, but may offer better performance per dollar compared to NA upgrades.
  • Reliability: Naturally aspirated setups are typically simpler and may require less maintenance over time.

Conclusion

Ultimately, the choice between turbocharging and naturally aspirated upgrades for the FA20 engine depends on your performance goals, budget, and driving preferences. Turbocharging offers substantial power gains and efficiency, while naturally aspirated upgrades provide a more straightforward and engaging driving experience. Consider your priorities carefully to make the best decision for your vehicle.
