Engine Upgrades

The heart of every Subaru lies in its engine, and upgrading this core component can unlock a world of untapped potential. From enhancing horsepower to improving overall efficiency, engine upgrades are the key to transforming your Subaru into a true performance machine.

1. High-Performance Turbochargers

Turbochargers play a critical role in Subaru's famed performance reputation, but factory turbos tend to have their limits. Upgrading to a larger or ball-bearing turbocharger can significantly increase airflow into the engine, delivering more horsepower and torque. Pair your new turbo with supporting upgrades to safely maximize output.

2. Cold Air Intakes

A cold air intake is one of the simplest and most cost-effective ways to boost your Subaru's efficiency and power. Designed to bring colder, denser air into your engine, these intakes improve combustion for a noticeable kick in performance. Plus, the added induction sound adds a thrilling edge to your driving experience.

3. Upgraded Intercoolers

When you boost power with a turbocharger, heat levels rise. An upgraded intercooler ensures that your engine stays cool by efficiently cooling the pressurized air coming from the turbo. Whether you choose a front-mount or top-mount intercooler design, this upgrade improves reliability as well as sustained performance.

4. Fuel System Upgrades

More power demands more fuel. Upgrading your fuel injectors, pump, and regulator ensures your engine gets the right amount of fuel for optimal combustion under higher boost conditions. These modifications are critical when paired with enhanced turbos or tuning. This is because it prevents fuel starvation and maximizes engine output.

5. Performance Pistons and Connecting Rods

If you're chasing big horsepower numbers, upgrading internals like pistons and connecting rods is a must. Strengthened performance pistons and rods can handle the increased stress from high horsepower builds, giving you peace of mind as you push your Subaru harder.

Upgraded Exhaust Systems

Unleashing your Subaru’s full potential starts with optimizing how it breathes. An upgraded exhaust system will enhance performance by improving airflow and delivers a deeper, more aggressive sound that truly transforms your driving experience.

1. Cat-Back Exhaust Systems

A cat-back exhaust system replaces the piping from the catalytic converter to the exhaust tip. By reducing back pressure and improving exhaust flow, a cat-back system can unlock additional horsepower and improve throttle response. Plus, it adds that signature Subaru rumble!

2. Upgraded Downpipes

For turbocharged Subarus, an upgraded downpipe is a game-changer. It allows exhaust gases to exit the turbo faster, reducing turbo lag and increasing horsepower. Pair your downpipe with proper tuning to maximize performance gains.

3. Header Upgrades

Exhaust headers are all about improving exhaust gas flow from your engine's cylinders. Upgrading to equal-length headers, in particular, can balance exhaust pulses and enhance overall engine output. They also alter the sound profile of your Subaru, creating a cleaner and more refined tone.

Suspension Enhancements

Whether you're chasing sharper handling on the track or a smoother, more controlled ride on daily commutes, suspension enhancements ensure your vehicle performs at its best in every condition.

1. Coilovers

Coilovers are adjustable suspension components that allow you to control ride height and stiffness. Whether you're setting up for track days or spirited backroad drives, coilovers give you precise control over how your Subaru handles.

2. Sway Bars

Sway bars (or anti-roll bars) reduce body roll during cornering, giving your Subaru enhanced cornering capabilities. By upgrading to thicker sway bars, you’ll experience sharper handling and better overall driving responsiveness.

3. Lower Control Arms

Upgraded lower control arms provide improved alignment and adjustability for suspension geometry. This translates to better handling, reduced tire wear, and a more composed ride during aggressive driving.

4. Strut Braces

Installing strut braces helps reduce flex between the suspension towers, improving chassis rigidity and overall cornering stability. This upgrade pairs well with other suspension mods to create a precise driving feel.

Tuning Options

No list of Subaru performance parts would be complete without mentioning tuning. Tuning allows you to fine-tune your car's performance and extract every bit of potential from your modifications.

1. Accessport Tuning

The Cobb Accessport is a favorite among Subaru enthusiasts for its ease of use and proven results. This handheld device lets you flash preloaded performance maps or create custom tunes for your car. The Accessport’s real-time diagnostics and data monitoring make it an essential tool for serious Subaru modifiers.

2. Boost Controllers

If you’ve upgraded your turbo, a boost controller lets you manage turbo pressure for consistent and optimized performance. Pair it with professional tuning to ensure safe operation.

Bonus Mods for the Extra Edge

Looking for that final touch? These bonus mods provide extra reliability and performance.

1. Oil Cooler Kits

High-performance driving generates heat, and an oil cooler kit helps keep temperatures under control. This is especially important for track days or heavily modified builds.

2. Performance Clutch Kits

Handling increased horsepower requires a clutch that can cope. An upgraded performance clutch kit provides improved durability and precision for sporty driving and quicker shifts.

3. Big Brake Kits

With great power comes a need for great stopping power. Big brake kits offer larger rotors and more powerful calipers, giving you the confidence to push your Subaru harder while staying safe.

There’s nothing quite like the thrill of driving a fully optimized Subaru WRX or STI. With the right upgrades, you can unleash your car’s full potential and redefine what it means to drive.
