The FA24 engine, found in the Subaru BRZ and Toyota GR86, has gained popularity among car enthusiasts for its potential to be modified for increased performance. If you’re looking to achieve significant horsepower gains, there are several upgrades you can consider. Here, we outline the top 10 power upgrades that can help you achieve over 50 horsepower gains on your FA24 engine.
1. ECU Tune
A proper ECU tune can unlock the full potential of your FA24 engine. By optimizing fuel maps and ignition timing, you can see substantial power increases. Many companies offer off-the-shelf tunes, while custom tuning can provide even better results.
2. Cold Air Intake
Installing a cold air intake can improve airflow to the engine, resulting in better combustion and increased horsepower. This upgrade is relatively easy to install and can provide noticeable gains.
3. Cat-Back Exhaust System
A cat-back exhaust system can enhance exhaust flow and reduce back pressure, allowing the engine to breathe better. This upgrade not only improves performance but also gives your vehicle a more aggressive sound.
4. Turbocharger Upgrade
For those looking for serious power gains, upgrading the turbocharger is a game-changer. A larger turbo can significantly increase boost pressure, resulting in higher horsepower and torque figures.
5. Intercooler Upgrade
Improving the intercooler can help lower intake temperatures, allowing for denser air entering the engine. This leads to better performance and efficiency, especially when paired with a turbo upgrade.
6. High-Performance Fuel Injectors
Upgrading to high-performance fuel injectors can ensure that your engine receives the right amount of fuel, especially when modifications increase airflow. This is crucial for maintaining the optimal air-fuel ratio and maximizing power.
7. Performance Camshafts
Performance camshafts can optimize valve timing and lift, allowing for better airflow through the engine. This upgrade can lead to significant horsepower gains, especially when combined with other modifications.
8. Lightweight Flywheel
A lightweight flywheel can reduce rotational mass, allowing the engine to rev more freely. This can improve throttle response and acceleration, enhancing the overall driving experience.
9. Upgraded Spark Plugs
High-performance spark plugs can improve ignition efficiency, leading to better combustion and power delivery. This upgrade is often overlooked but can have a positive impact on performance.
10. Exhaust Manifold Upgrade
Upgrading the exhaust manifold can improve exhaust flow and reduce turbo lag, leading to quicker spool times and increased power. This modification is essential for those looking to maximize their engine’s performance.
Conclusion
With the right upgrades, the FA24 engine in your Subaru BRZ or Toyota GR86 can achieve impressive horsepower gains. Whether you choose to start with a simple ECU tune or go all out with a turbo upgrade, each modification can contribute to a more powerful and enjoyable driving experience.
