The Subaru BRZ FA20 is a beloved sports car known for its lightweight design and responsive handling. However, many enthusiasts seek to enhance its performance without breaking the bank. In this article, we will explore how you can add approximately 40 horsepower to your BRZ FA20 with just $600 in basic modifications.
Understanding the FA20 Engine
The FA20 engine, a 2.0-liter flat-four, is the heart of the BRZ. While it delivers an enjoyable driving experience, there is potential for improvement. Understanding the engine’s characteristics and limitations is crucial for effective modifications.
- Engine Type: Naturally aspirated 2.0L flat-four
- Stock Horsepower: Approximately 200 hp
- Torque: Around 151 lb-ft
Budget Modifications Overview
To achieve a boost of 40 hp, we will focus on three key modifications that are both affordable and effective. These modifications include an aftermarket cold air intake, a cat-back exhaust system, and an ECU tune.
1. Aftermarket Cold Air Intake
A cold air intake system improves airflow to the engine, enhancing combustion efficiency. This modification is relatively inexpensive and can provide a noticeable increase in horsepower.
- Improves airflow to the engine
- Enhances throttle response
- Typically costs between $200 – $300
2. Cat-Back Exhaust System
A cat-back exhaust system replaces the factory exhaust from the catalytic converter back. This modification not only improves exhaust flow but also adds a more aggressive sound to your BRZ.
- Reduces back pressure
- Enhances engine sound
- Cost ranges from $300 – $400
3. ECU Tune
An ECU tune recalibrates the engine’s computer to optimize performance based on the new modifications. This step is essential for unlocking the full potential of the intake and exhaust upgrades.
- Increases horsepower and torque
- Cost-effective tuning options available
- Typically priced around $200
Estimated Costs and Benefits
Here’s a breakdown of the estimated costs for each modification:
- Cold Air Intake: $250
- Cat-Back Exhaust: $350
- ECU Tune: $200
Total Estimated Cost: $800
While this total exceeds our $600 target, you can often find used parts or sales that can bring costs down. The benefits, however, are substantial:
- Increased horsepower: Approximately 40 hp gain
- Enhanced driving experience
- Improved engine sound and responsiveness
Installation Tips
For those who are comfortable with basic mechanical tasks, installation of these modifications can often be done at home. Here are some tips:
- Follow manufacturer instructions carefully.
- Use proper tools and safety equipment.
- Consider enlisting a friend for assistance.
Conclusion
Boosting your BRZ FA20’s horsepower doesn’t have to be expensive. With careful planning and the right modifications, you can achieve a significant performance upgrade on a budget. The combination of a cold air intake, cat-back exhaust, and ECU tune can transform your driving experience, making your BRZ even more enjoyable on the road or track.
