Fa20 Engine Build Cost Analysis: Supercharger Vsturbocharged Power Gains

The FA20 engine is a popular choice among automotive enthusiasts, particularly for those looking to enhance performance through forced induction. In this article, we will conduct a cost analysis comparing the benefits and expenses associated with supercharging versus turbocharging the FA20 engine.

Understanding the FA20 Engine

The FA20 engine is a flat-four engine developed by Subaru and Toyota. It is known for its compact size, lightweight design, and balanced performance. The engine is commonly found in vehicles like the Subaru BRZ and Toyota 86. Before diving into the cost analysis, it’s essential to understand the fundamentals of the FA20 engine’s design and capabilities.

Supercharging the FA20 Engine

Supercharging involves using a belt-driven compressor to force more air into the engine’s intake. This process increases the engine’s power output and efficiency. Let’s explore the costs associated with supercharging the FA20 engine.

Cost Breakdown for Supercharging

  • Supercharger Kit: $3,000 – $6,000
  • Installation Costs: $1,000 – $2,000
  • Tuning: $500 – $1,500
  • Supporting Mods (fuel pump, injectors): $500 – $1,000

In total, the cost of supercharging the FA20 engine can range from approximately $5,000 to $10,500, depending on the quality of parts and labor costs.

Turbocharging the FA20 Engine

Turbocharging utilizes exhaust gases to spin a turbine, which then compresses the intake air. This method can provide significant power gains while often being more efficient than supercharging. Let’s look at the costs related to turbocharging the FA20 engine.

Cost Breakdown for Turbocharging

  • Turbocharger Kit: $2,500 – $5,000
  • Installation Costs: $1,000 – $2,000
  • Tuning: $500 – $1,500
  • Supporting Mods (intercooler, exhaust): $500 – $1,000

The total cost of turbocharging the FA20 engine typically ranges from $4,500 to $10,500, depending on the components and installation choices.

Power Gains Comparison

Both supercharging and turbocharging can yield impressive power gains. However, the nature of these gains can differ significantly.

Supercharged Power Gains

Supercharging the FA20 engine can result in power gains of approximately 30% to 50%. This increase in power is often accompanied by a more linear power delivery, making it suitable for drivers who prefer a consistent power band.

Turbocharged Power Gains

Turbocharging can provide power gains ranging from 40% to 70%. The power delivery may be more aggressive, with a noticeable boost in power at higher RPMs. This characteristic can appeal to those looking for a more dynamic driving experience.

Considerations for Choosing Between Supercharging and Turbocharging

When deciding between supercharging and turbocharging the FA20 engine, several factors should be taken into account:

  • Cost: Assess your budget and the total costs associated with each option.
  • Power Delivery: Consider your driving style and preference for power delivery.
  • Reliability: Evaluate the reliability of each setup and potential maintenance costs.
  • Installation Complexity: Consider the complexity of installation and tuning required for each option.

Conclusion

In conclusion, both supercharging and turbocharging the FA20 engine offer unique benefits and challenges. Supercharging tends to provide a more linear power delivery, while turbocharging can yield higher peak power. Ultimately, the decision will depend on individual preferences, budget, and desired driving experience. Whether you choose to supercharge or turbocharge, enhancing your FA20 engine can lead to an exhilarating driving experience.
