Upgrading your FA20 engine to achieve over 300 horsepower can seem like a daunting task, especially when working with a budget of $2,000. However, with careful planning and strategic choices, it is possible to reach this performance milestone without breaking the bank. This article will provide a detailed cost breakdown for various upgrades and modifications that can help you achieve your horsepower goals.
Understanding the FA20 Engine
The FA20 engine, found in vehicles like the Subaru BRZ and Toyota 86, is a flat-four engine known for its lightweight design and balanced performance. To unlock its full potential, several modifications can be made, each contributing to increased horsepower and torque.
Key Upgrades for Increased Power
- Cold Air Intake
- Performance Exhaust System
- Tune/ECU Remapping
- Upgraded Turbocharger
- Intercooler Upgrade
1. Cold Air Intake
A cold air intake system helps the engine breathe better by allowing cooler air to enter. This modification can provide a noticeable increase in horsepower.
Estimated Cost: $300 – $500
2. Performance Exhaust System
Upgrading the exhaust system can reduce back pressure and improve exhaust flow, leading to better engine performance. A performance exhaust also enhances the engine’s sound.
Estimated Cost: $500 – $800
3. Tune/ECU Remapping
Reprogramming the engine’s ECU can optimize performance by adjusting fuel maps and ignition timing. This is often one of the most effective upgrades for increasing horsepower.
Estimated Cost: $300 – $600
4. Upgraded Turbocharger
If your FA20 engine is turbocharged, upgrading to a larger turbo can significantly boost horsepower. This modification requires careful consideration of supporting components.
Estimated Cost: $600 – $1,000
5. Intercooler Upgrade
An upgraded intercooler helps to cool the air entering the engine, which can improve performance and prevent knock. This is particularly important for turbocharged engines.
Estimated Cost: $400 – $700
Cost Breakdown Summary
Here’s a summary of the estimated costs for each upgrade:
- Cold Air Intake: $300 – $500
- Performance Exhaust System: $500 – $800
- Tune/ECU Remapping: $300 – $600
- Upgraded Turbocharger: $600 – $1,000
- Intercooler Upgrade: $400 – $700
Maximizing Your Budget
To stay within the $2,000 budget while achieving 300+ HP, prioritize upgrades based on your specific goals and vehicle setup. Here are a few strategies:
- Start with the cold air intake and performance exhaust system for immediate gains.
- Consider a tune as a fundamental upgrade that complements other modifications.
- Evaluate whether an upgraded turbocharger is necessary based on your power goals.
- Look for used parts or sales to save on costs.
Conclusion
Upgrading your FA20 engine to achieve over 300 horsepower on a $2,000 budget is feasible with the right approach. By strategically selecting upgrades and prioritizing essential modifications, you can enhance performance while staying within your financial limits. With careful planning and execution, your FA20 can become a powerful machine that delivers the performance you desire.
