Garrett G42-1325 G-Series II Super Core

If you're building a high-performance engine and looking to significantly increase horsepower, a robust super core assembly like the Garrett G42-1325 G-Series II is a critical component. This is the heart of a custom turbocharger setup, designed to force more air into your engine, allowing it to burn more fuel and generate substantially more power. It’s the kind of part you select when you're aiming for serious performance gains and need a reliable foundation for your forced induction system.

The G42-1325 is built with Garrett's G-Series II technology, featuring an advanced aerodynamic compressor wheel made from forged-milled aluminum. This design helps improve airflow efficiency and durability, which translates to better boost response and sustained power delivery. The turbine housing is cast from stainless steel, offering excellent resistance to high temperatures and corrosion, crucial for managing the extreme heat generated in a performance application. This super core assembly is designed for builders who need a powerful and dependable unit that can handle demanding conditions and deliver consistent performance.

This assembly includes the core components needed to build a complete turbocharger. You'll need to select compatible turbine housings and other supporting components to complete your turbocharger build. Because this is a super core, it's intended for custom applications where precise control over airflow and fitment is paramount. It's important to note that this unit is not CARB approved and cannot be shipped to California due to emissions regulations.
