Product Description

The Garrett 938339-5003S G42-1585 Super Core Turbocharger is a high-flow performance turbo core designed for custom turbocharger builds and motorsport applications. This G-Series II Super Core delivers enhanced compressor airflow - up to roughly 10 % more than previous Gen I designs - while supporting an extensive horsepower range of approximately 475 HP to over 1500 HP when properly configured and tuned.

Because this unit is a **super core assembly** (not a complete bolt-on turbo for any specific production vehicle), it requires a compatible turbine housing, exhaust manifold interface, oil and coolant feeds, and calibrated engine management to function properly. It's ideal for professionals, engine builders, and tuners constructing high-boost turbo systems on engines from roughly 2.0 L to 7.0 L displacement. Always verify component compatibility with your specific turbo kit setup before installation.
