Inside the Build: Audi S3 by GDO Automotive

At GDO Automotive, we don’t just modify cars — we build machines with purpose. Our latest project, a fully re-engineered Audi S3, redefines the potential of the MQB platform. With an expertly selected mix of high-performance components, advanced fuel system upgrades, and turbocharged innovation, this build stands as a benchmark for what’s possible on both street and strip.

More Than Stage 2: A Transformation With Purpose

This isn’t your average Stage 2 tune. It’s a strategic performance overhaul engineered for power, reliability, and long-term adaptability — especially for E85 users. The result? A solid 550 horsepower, delivered with consistency, control, and confidence.

Let’s dive into the heart of the build.

Power That Responds: EQT Vortex XL Turbo

At the center of this powerhouse is the EQT Vortex XL Turbo — a proven performer that delivers serious top-end horsepower while preserving low-end responsiveness. Built for both daily driving and track demands, it delivers strong, lag-free boost when it counts.

Maximized Airflow: Blaze Performance AToM V2 Intake

To meet the increased airflow demands, we equipped the car with the Blaze Performance AToM V2 Intake. This intake system ensures optimal air delivery, low intake temps, and responsive throttle — making it the ideal complement to the Vortex XL’s capabilities.

Fueling the Future: Full Flex-Fuel Capability

Big boost demands serious fueling. That’s why this S3 features a full flex-fuel conversion, unlocking both performance and versatility — especially for ethanol (E85) users. Highlights include:

• EQT MPI Kit – enhanced fuel distribution under high load
• COBB Flex Fuel Kit + Precision Raceworks Adapter – automatic ethanol content adjustment
• Brushless High-Pressure Fuel Pump – consistent delivery under pressure
• Precision Raceworks Braided Fuel Lines – built for durability, safety, and ethanol resistance

This setup allows the engine to safely extract more power across various fuel blends — without compromise.

Precision Built, Purpose Tuned

Every component on this Audi S3 was selected to create a seamless, reliable, and powerful driving experience. No excess. No shortcuts. Just a well-balanced, flex-fuel-ready machine that delivers approximately 550 horsepower — and does it every time you step on the throttle.

Whether you’re chasing lap times or weekend thrills, this build shows what happens when engineering meets intention.
