The Subaru BRZ, equipped with the FA20 engine, is known for its lightweight design and agile handling. However, many enthusiasts seek to enhance its performance without breaking the bank. In this article, we will explore cost-effective upgrades that can yield significant horsepower gains, all under $1,500.
Understanding the FA20 Engine
The FA20 engine is a flat-four, naturally aspirated powerplant that delivers a well-balanced performance. With a stock output of around 200 horsepower, many owners are eager to unlock more potential. Understanding the engine’s characteristics is crucial for selecting the right upgrades.
Top Upgrades for Performance
Here are some of the most effective upgrades you can implement to increase horsepower while staying within budget:
- Cold Air Intake System: Upgrading to a high-performance cold air intake can improve airflow to the engine, resulting in a noticeable increase in horsepower.
- Cat-Back Exhaust System: A cat-back exhaust system enhances exhaust flow, reduces back pressure, and can add a few extra horsepower while giving your BRZ a more aggressive sound.
- Tune: A proper ECU tune can optimize fuel delivery and ignition timing, maximizing the gains from your other upgrades.
- Header Upgrade: Replacing the stock headers with performance headers can improve exhaust flow significantly, contributing to horsepower gains.
- Lightweight Flywheel: A lightweight flywheel reduces rotational mass, allowing the engine to rev more freely and improving throttle response.
Detailed Breakdown of Each Upgrade
Cold Air Intake System
Installing a cold air intake system can enhance engine performance by allowing cooler, denser air to enter the engine. This upgrade typically costs between $200 and $500 and can yield gains of 5-10 horsepower.
Cat-Back Exhaust System
A cat-back exhaust system replaces the exhaust components from the catalytic converter back. Prices range from $500 to $1,200, and you can expect an increase of 5-15 horsepower, along with improved sound.
Tune
Investing in a professional ECU tune can cost between $300 and $600. A proper tune adjusts the air-fuel mixture and ignition timing, potentially adding 10-20 horsepower depending on your other modifications.
Header Upgrade
Performance headers can cost between $400 and $800 and can provide gains of 5-10 horsepower. They improve exhaust flow and can enhance the overall sound of your vehicle.
Lightweight Flywheel
A lightweight flywheel can be purchased for around $400 to $600. This upgrade enhances throttle response and can provide a more engaging driving experience, though it may not add significant horsepower directly.
Combining Upgrades for Maximum Gains
To achieve the best results, consider combining several of these upgrades. For example, pairing a cold air intake with a cat-back exhaust and a tune can lead to substantial performance improvements without exceeding your budget.
Conclusion
Upgrading your Subaru BRZ FA20 engine can be both cost-effective and rewarding. By investing in a few key performance enhancements, you can achieve over 20 horsepower gains for under $1,500. Happy tuning!
