Why the 50 Trim T3/T4E?

While many modern turbos use complex ball-bearing systems, the 466159-5011S relies on a rugged journal-bearing design that is easier to maintain and more forgiving in harsh environments. The 50-trim compressor wheel is exceptionally efficient, meaning it moves a large volume of air without generating excessive heat, making it a favorite for:

• Honda B/D/K-Series turbo conversions.
• BMW E30/E36 low-boost builds.
• Volkswagen 1.8T longitudinal upgrades.
• Nissan SR20/KA24 street setups.

Features & Benefits:

• Simplified Plumbing: As an oil-cooled unit, you don’t need to tap into your vehicle’s cooling system, making it ideal for custom builds and engine swaps.
• Stage III Turbine Wheel: The larger Stage 3 wheel reduces exhaust backpressure compared to standard T3 units, allowing for much better top-end flow.
• Garrett Reliability: Factory-assembled and high-speed balanced by Garrett Motion for OE-level longevity and “set-it-and-forget-it” performance.

Note: This unit is designed for use with an external wastegate. Ensure your manifold is wastegate-ready or that you have an external gate setup in your exhaust path.

Building on 70 years of aerospace-derived expertise and a legacy of technological leadership, Garrett Motion’s performance range is engineered for enthusiasts and professional racers who demand elite-level results. From winning 26 consecutive titles at the 24 Hours of Le Mans to powering world-class Formula 1 and rally teams, Garrett’s performance products—including the cutting-edge G-Series, G-XRace, and GTX lineups—deliver reliable power and consistent airflow. Every component is designed to bridge the gap between track-proven durability and street-driven innovation, ensuring your build benefits from the same high-speed technology that has shaped the global automotive industry.
