Subaru is a global car company that almost everyone knows. These vehicles are renowned for their ability to handle a wide range of road conditions with ease due to their unique Boxer engine and symmetrical all-wheel drive. Unlike most engines, which have pistons that move up and down, a Boxer engine’s pistons move side to side in pairs, creating a flat engine layout.
According to Subaru’s Accolade page, 92% of Subaru WRX vehicles sold over the last ten years are still on the road today, revealing the brand’s reputation for long-term reliability. If you’re someone who likes to get more out of your Subaru, adding upgrades is probably top of your list. Keep reading to find out which upgrades really make a difference.
Engine Upgrades
One of the best ways to increase a car’s power, efficiency, and overall driving performance is to upgrade the engine. Turbochargers, cold air intakes, and fuel system upgrades are popular options that work.
High-Performance Turbochargers
Turbochargers give an engine more power by pumping more air into it. By forcing more air into it, fuel burns more efficiently, which generates far more horsepower and torque than stock parts. On Subarus like the WRX or XTI, upgrades like a 20G turbocharger can significantly increase acceleration and mid-range power, making them ideal if you prioritize responsiveness.
Cold Air Intakes
By letting cooler air that has more oxygen into the engine, upgraded cold air intakes improve how well the engine turns fuel into power, boosting vehicle performance and delivering real gains. A Subaru WRX with an upgraded air intake, for example, helps the turbo spool function more efficiently, enhancing responsiveness and mid-range torque.
Fuel System Upgrades
A high-performance fuel system upgrade is essential for optimal engine performance, as it ensures the engine gets enough fuel to support increased airflow. If you have larger fuel injectors and a fuel pump with high-flow capacity on a turbocharged Subaru WRX, it will help maintain safe air-fuel ratios when the turbo is spooled.
Performance Wheel Upgrades
Subaru wheels are an upgrade that can boost a vehicle’s handling and performance by reducing unsupported weight and improving stability. It also provides better acceleration, braking, and responsiveness with lightweight, performance-focused wheels. Overall, Subaru wheels paired with proper tires can help maximize grip and keep a car stuck to the road.
Consider lightweight forged wheels, for example. They reduce the mass that isn’t supported by the suspension, allowing it to respond to uneven surfaces so the tires can stay firmly planted on the road. Also, a car with less rotational mass is able to change directions faster and use less energy to spin the wheels, providing real performance results.
Upgrade the Drivetrain
Drivetrain upgrades can help a Subaru deal with extra power and performance demands by strengthening the parts that move power from the engine to the wheels. Parts like clutches, lightweight flywheels, and reinforced axles deliver better power under high-performance driving. These changes improve responsiveness, especially when combined with other upgrades like the following:
- Turbocharger upgrades
- ECU tuning
- High-flow exhaust systems
- Upgraded fuel system parts
Suspension Upgrades
Suspension upgrades enhance handling and stability by improving how a car responds to the road. Steering, suspension linkage, and chassis bracing are upgrades that deliver results.
Steering System Upgrades
With improved steering, a Subaru reacts more precisely, providing more control when driving. Parts like strengthened steering shaft couplers, better tie rod ends, and more durable steering rack bushings improve response and reduce instability. Together, these car modifications make steering feel sharper and more precise, especially at high speeds.
Suspension Linkage Upgrades
By strengthening the connections between suspension parts, linkage modifications reduce unwanted movement and increase stability. Upgrades that improve alignment consistency in demanding conditions include adjustable toe links, rear lower control arm braces, and adjustable sway bar endlinks.
Chassis Bracing Upgrades
Upgrades to the chassis bracing increase the strength of the chassis and reduce body and suspension mounting point flex. Front underbraces, rear subframe braces, and front strut tower braces are examples of parts that support alignment and improve how well a car handles the road. As a result, the ride is steadier and more predictable, particularly when driving aggressively.
In Conclusion
What makes these Subaru upgrades so popular is that each of them provides a noticeable improvement in actual performance, including power, handling, and control. Engine upgrades like turbochargers increase horsepower and torque gains, while performance wheels keep the car planted under hard driving. Combine that with suspension upgrades, and you get driving improvements you can really feel.
