When you choose our Subaru STI upgrades, you’re getting components developed with an insider’s understanding of the platform, ensuring seamless integration and dependable performance that honors the Subaru legacy.

Our roots are planted firmly in motorsports, and that experience drives everything we do. We apply our deep background, including our iconic work with Ken Block, to develop specialized, high-quality upgrades for Subaru models from 2002 to the present. We don’t just adapt generic parts; we engineer custom-designed performance parts built specifically for the unique demands of Subaru engines.

Get Maximum Power with These WRX STI Upgrades
Taking your WRX STI from a capable street car to a true performance machine requires a thoughtful approach to modifications. It’s not just about bolting on parts; it’s about creating a balanced system where each component works in harmony to deliver reliable power and exceptional handling. Whether your goal is to dominate on track days or simply enjoy a more responsive daily driver, the right combination of upgrades is key to achieving your goals without sacrificing dependability.
We’ve spent decades perfecting our craft, engineering parts that extract the maximum potential from the Subaru platform. Our deep experience, including our work with Subaru of America and legends like Ken Block, informs every product we design. This means you're getting components that have been tested in the most demanding environments. Below, we’ll walk through the essential upgrades that will transform your vehicle’s performance, starting from the heart of the engine and moving outward to the components that put that power to the ground. These are the track-proven parts that will help you build the STI you’ve always envisioned.
Engine Packages and Short Blocks
The foundation of any serious power build is the engine itself. Before you can push for higher horsepower, you need to ensure the core of your vehicle can handle the stress. Crawford Performance builds custom long block engines for Subaru WRX and STI models that are specifically designed for high power, strong performance, and lasting reliability. Each engine is assembled with precision and tested to withstand the demands of both track and street use. Investing in one of our built engine packages provides the durable foundation you need to confidently add more power through other modifications, knowing your motor is up to the task.
Gymkhana-Inspired Exhaust Systems
An exhaust system does more than just give your STI its signature rumble; it’s critical for performance. A high-flow exhaust allows your engine to breathe more efficiently, expelling gases faster to make way for more air and fuel. This process directly translates to increased horsepower and torque. We apply our deep motorsports background, including our work with Ken Block, to develop specialized Subaru STI upgrades. Our Gymkhana-inspired exhaust systems are engineered not just for an aggressive sound but for proven power gains, giving your vehicle a competitive edge that’s born from real-world racing experience.
Turbocharger and Intake Upgrades
To make big power, your engine needs more air, and that’s where turbocharger and intake upgrades come in. A larger, more efficient turbo forces more compressed air into the engine, while an upgraded intake ensures that air is cool, dense, and delivered without restriction. The key is to choose high-quality, Subaru-specific parts that are designed with your vehicle’s precise engineering in mind. Our performance parts are engineered to work seamlessly with your STI, avoiding the installation headaches and poor results that often come with generic components. This synergy ensures you get the power you want without compromising reliability.
Suspension and Handling Components
All the horsepower in the world is useless if you can’t control it. Upgrading your suspension is essential for putting power to the ground effectively and improving your car’s overall dynamics. Coilovers, sway bars, and other handling components transform how your STI feels in the corners, providing greater stability, sharper turn-in, and more feedback to the driver. Crawford Performance designs and manufactures expertly engineered, high-quality Subaru WRX upgrades for both the track and the street. These components give you the confidence to push your car to its limits, knowing it will respond predictably and precisely to your every input.

Building for the Track
If you’re preparing your WRX or STI for the track, you need parts that deliver maximum performance and can withstand extreme conditions. Our deep roots in motorsports, including our work with the legendary Ken Block, inform every track-focused component we design. We engineer our Subaru STI Upgrades to provide reliable power and sharp handling lap after lap. This means focusing on a balanced setup, from a built short block that can handle high boost to a suspension system that keeps you planted in the corners. It’s not just about adding horsepower; it’s about creating a responsive and durable machine you can push to its limits with confidence.
Upgrading Your Daily Driver
You don’t have to be a track warrior to want more from your Subaru. For a daily driver, the goal is to enhance performance without sacrificing comfort and reliability. You want a car that’s more engaging and fun to drive on your commute or on a spirited weekend cruise. This is where the right combination of parts and professional tuning makes all the difference. Our comprehensive Engine Tuning Services can refine your vehicle’s performance, ensuring smooth power delivery and improved throttle response. An upgraded intake, exhaust, and a custom tune can completely transform your driving experience, giving you a noticeable performance gain that you can enjoy every day.
Finding Value for Your Budget
Building a high-performance Subaru is an investment, and getting the best value is crucial. While it might be tempting to opt for cheaper, generic parts, this approach often leads to installation issues, poor performance, and more costs down the road. The smartest way to spend your money is on high-quality, Subaru-specific Performance Parts designed with your vehicle’s engineering in mind. Prioritize foundational upgrades first, like a solid engine block or a reliable air-oil separator. Investing in the right components from the start ensures reliability and provides a strong platform for future modifications, saving you from costly repairs and replacements.
Exploring Package Deals and Financing
One of the most effective ways to plan your build is by looking at curated packages. These bundles often provide better value than buying each part individually and guarantee that all components are designed to work together seamlessly. This takes the guesswork out of your build and ensures you get a balanced, reliable setup. We often have promotions and special offers available, so it’s always a good idea to see what’s current. For larger projects, financing can also be a great option, allowing you to get all the parts you need at once to complete your build without compromise.
