This BorgWarner SuperCore Assembly, part number 12747100021, is the core component for building a custom forced induction setup. It includes the essential rotating assembly and housing that form the heart of a turbocharger system. This specific unit features an aluminum bearing housing, which helps manage heat and keep overall weight down. It's designed for enthusiasts looking to build a high-performance engine with a reliable and well-known turbocharger core.

The EFR (Engineered for Racing) series from BorgWarner is known for its robust construction and advanced features. This B2 SuperCore assembly is built with durability in mind, featuring a well-built bearing system designed to handle the stresses of high boost pressures and temperatures. The aluminum housing is a key component in dissipating heat effectively, which is crucial for maintaining consistent performance and extending the life of the turbocharger. While this is a core assembly, it's intended to be integrated into a complete turbocharger system, meaning you'll need to source or fabricate the exhaust housing and other necessary components to complete the unit for your specific application.

When planning your build, remember that this assembly is not CARB approved and cannot be shipped to California. It's important to consult with your engine builder or a turbo specialist to ensure this core assembly is the right fit for your project's power goals and engine configuration. Proper installation and tuning are critical for optimal performance and longevity.
