Summary
- A high-flow air filter, like a K&N or AEM, will allow more air into the engine, increasing airflow and horsepower.
- Opt for a system with a larger diameter and a free-flowing muffler for optimal performance.
- A front splitter, rear diffuser, and a spoiler can improve downforce and reduce drag, enhancing stability and performance at higher speeds.
The Subaru Legacy is a beloved car known for its reliability, safety, and all-wheel drive prowess. But what if you want more than just practicality? What if you want to unleash the hidden beast within and make your Legacy truly fly?
This guide will explore various ways to how to make my Subaru Legacy faster, from simple modifications to more advanced upgrades. We’ll cover everything from engine tuning to suspension tweaks, helping you transform your Legacy into a performance machine.
1. Breathe Easy: Intake and Exhaust Upgrades
The first step to unlocking more power is giving your engine a chance to breathe freely. This means upgrading the intake and exhaust systems.
- Intake: A high-flow air filter, like a K&N or AEM, will allow more air into the engine, increasing airflow and horsepower. Consider a cold air intake for even better results.
- Exhaust: A cat-back exhaust system, replacing the exhaust from the catalytic converter back, can significantly reduce backpressure and improve exhaust flow. Opt for a system with a larger diameter and a free-flowing muffler for optimal performance.
2. Tune It Up: ECU Tuning and Performance Chips
Modern cars have sophisticated engine control units (ECUs) that govern various engine parameters. By tuning the ECU, you can optimize these settings for increased power and performance.
- ECU Tuning: A professional tuner can remap your ECU to adjust parameters like ignition timing, fuel delivery, and boost pressure. This can result in noticeable horsepower and torque gains.
- Performance Chips: While less sophisticated than ECU tuning, performance chips offer a plug-and-play solution that can provide modest power increases. However, they often come with pre-programmed settings that may not be optimal for your specific Legacy.
3. Unleash the Turbo: Turbocharger Upgrades
If your Legacy is equipped with a turbocharged engine, upgrading the turbocharger can unlock a significant power boost.
- Larger Turbocharger: A larger turbocharger can handle more airflow, resulting in increased boost pressure and horsepower. However, it may require other modifications, such as a larger intercooler, to ensure optimal performance.
- Turbocharger Upgrades: Consider upgrading the turbocharger’s components, such as the impeller, turbine, or bearings, for improved efficiency and responsiveness.
4. Suspension Tweaks: Handling and Performance
While not directly related to engine power, suspension modifications can significantly enhance your Legacy’s handling and performance.
- Lowering Springs: Lowering springs decrease the ride height, improving cornering stability and reducing body roll. However, it can affect ride comfort and ground clearance.
- Coilovers: Coilovers offer adjustable ride height, damping, and spring rates, allowing you to fine-tune your suspension for optimal performance and handling.
- Anti-Roll Bars: Thicker anti-roll bars reduce body roll in corners, improving handling and responsiveness.
5. Wheel and Tire Upgrades: Grip and Performance
The right wheels and tires are crucial for maximizing your Legacy’s performance.
- Lightweight Wheels: Lighter wheels reduce unsprung weight, improving acceleration, braking, and handling.
- Performance Tires: High-performance tires offer better grip, cornering, and braking capabilities, essential for maximizing your Legacy’s potential.
6. Braking Power: Upgraded Brakes
To handle the increased power and speed, you’ll need a braking system that can keep up.
- Larger Rotors: Larger rotors provide more surface area for brake pads, improving braking performance and fade resistance.
- High-Performance Pads: Performance brake pads offer higher friction coefficients, resulting in shorter stopping distances and improved braking feel.
7. Finishing Touches: Aesthetics and Performance
Once you’ve implemented the performance upgrades, you can add some finishing touches to enhance your Legacy’s aesthetics and performance.
- Lightweight Body Parts: Replacing heavy body panels with lightweight components, such as carbon fiber or fiberglass, can reduce weight and improve performance.
- Aerodynamic Enhancements: A front splitter, rear diffuser, and a spoiler can improve downforce and reduce drag, enhancing stability and performance at higher speeds.
Beyond the Horizon: A Legacy of Power
By following these guidelines, you can unleash the hidden potential of your Subaru Legacy and transform it into a performance machine. Remember, how to make my Subaru Legacy faster is a journey, not a destination. Start with small upgrades and gradually build upon them, enjoying the process as your Legacy evolves into a true driving force.
Popular Questions
Q: Is it worth it to modify my Subaru Legacy for performance?
