Garrett TA3405 Turbocharger 50 Trim T3/T4E 0.63 A/R (Small Frame)

The 0.63 A/R turbine housing on this Garrett TA3405 turbocharger is a key spec, controlling exhaust gas flow into the turbine wheel. This particular unit features a 50 Trim compressor wheel and a T3/T4E footprint, making it a well-known option for enthusiasts looking to step up their vehicle's performance. It's a small frame turbo, which generally means it spools up quicker than larger frame units, offering a noticeable improvement in throttle response and overall power delivery for many applications.

Garrett has a long history in forced induction, and this turbocharger reflects that experience. The build quality is solid, designed to handle the increased demands of boosted engines. The 50 Trim compressor is a balanced choice, providing a good increase in airflow without being so large that it creates excessive lag. This makes it a popular selection for a wide range of builds where a responsive powerband is desired. While it's a small frame turbo, it's still a significant upgrade over stock for many naturally aspirated or smaller factory-turbocharged vehicles.

When installing a turbocharger like this, it's important to ensure your engine is properly tuned to take advantage of the increased airflow and to prevent detonation. Proper oil and coolant lines are also critical for longevity. This turbocharger is not CARB approved and cannot be shipped to California. Always consult with a professional tuner and mechanic to ensure your build is safe and optimized.
