🚗 Build Breakdown: Bryan’s 2020 Subaru STI – AWD Power Perfected 🚗
Bryan’s Subaru journey began with a humble start, but one that left a lasting impression. His first car wasn’t your typical enthusiast choice—it was a 1989 Subaru Justy 4x4, a small but incredibly capable car that gave Bryan a deep appreciation for Subaru's engineering, especially in wet and off-road conditions. Fast forward to today, and Bryan is behind the wheel of a 2020 Subaru STI that perfectly balances power, grip, and throttle response—a culmination of years of learning and understanding what makes a Subaru truly special.
For Bryan, the goal was never to go over the top with his build; instead, it was about refining the car into something that delivers exactly what he wanted from an STI—a car that performs flawlessly on the road and track while maintaining reliability.
The Power and Precision of AWD:
Bryan’s 2020 STI is all about delivering immediate power. The FP Green Turbo, paired with the Killer B Holy Header and ETS Intercooler, gives the car an exhilarating response right off the throttle. The power delivery is smooth, with Subaru’s AWD system making sure all that power hits the pavement with precision and grip. For Bryan, the fun isn’t just in the raw power—it’s in how seamlessly everything works together.
Bryan loves how the STI delivers instant power without hesitation, a characteristic that’s uniquely Subaru. Whether on the street or on the track, the STI feels dialed in, and the precision in the throttle response is something that Bryan cherishes.
Top Mods:
🔹 FP Green Turbo:
The FP Green Turbo is the heart of this build. Known for its ability to provide solid power and quick spool times, the FP Green turbocharger brings instant throttle response and impressive performance across the powerband. It’s a perfect match for Bryan’s goal of getting more from the STI while keeping it balanced and reliable.
🔹 ETS Intercooler:
With the added power from the FP Green Turbo, Bryan added the ETS Intercooler to keep temperatures in check and ensure consistent performance. This upgrade helps prevent heat soak during aggressive driving and track sessions, keeping the car’s performance sharp at all times.
🔹 Killer B Holy Header:
One of the standout modifications on Bryan’s STI is the Killer B Holy Header. Known for improving exhaust flow and boosting turbo efficiency, this header is an essential part of Bryan’s performance setup. It helps the turbo spool more efficiently, increasing the power output while also providing that signature Subaru rumble.

The Bride Zeta 3 seat is all about performance and comfort. This racing-inspired seat provides the right amount of support for spirited driving and track days, helping Bryan stay firmly planted in the driver’s seat while also looking stylish in the cockpit.

Bryan’s Take on the Build:
For Bryan, this 2020 STI is the perfect balance of power, reliability, and fun. He’s crafted a car that’s not just about raw power but about immediate throttle response and precise control—key elements of the AWD experience that Subaru enthusiasts love. Bryan’s philosophy with this build has always been about refining the STI, not overdoing it with unnecessary modifications. Every part of the build has been carefully selected to deliver exactly what he wants: performance, power, and reliability.
As Bryan puts it, "This car is everything I set out for. It’s responsive, reliable, and a thrill to drive every time. The next step is a Walbro 525 fuel pump to make sure I have a more reliable tune, but after that, I plan to leave it as-is—unless, of course, the block gives out, in which case I’ll be looking at a full build."
Future Plans:
While Bryan’s STI is already dialed in, there’s always room for improvement. The next step in his build is a Walbro 525 fuel pump upgrade, which will provide more consistent fuel delivery and make the car more reliable during higher boost or track days. After that, it’s all about enjoying the car as-is—unless the engine gives up, in which case Bryan may look into building the motor for even more power.
Bryan has always appreciated Subaru’s engineering and performance, and his 2020 STI is a perfect example of how a car can be tailored to your exact needs without going overboard. For now, Bryan is content with the way the car performs and looks—right in that sweet spot where everything just works.
