Description

The Garrett GT4508R Super Core is engineered for demanding performance applications, offering a robust foundation for custom turbo systems. This specific model, identified by Garrett Part # 742581-5004S, is a "Super Core," meaning it comes without a turbine housing, allowing for maximum flexibility in exhaust manifold and A/R selection. Key specifications for this turbocharger include a turbine wheel with an 80mm exducer and an 87mm inducer, complemented by an 85 trim. These dimensions are optimized for significant airflow and power potential, making it suitable for high-horsepower builds. The GT4508R is part of Garrett's renowned GT series, known for its advanced aerodynamics, dual ball-bearing technology (in some configurations, though this is a core), and enhanced durability. This turbocharger is intended for custom performance builds where precise control over exhaust flow and housing selection is critical. Users will need to source a compatible turbine housing that matches their specific engine and performance goals.
