BorgWarner 12647100008 EFR-7064 Turbocharger Cartridge Assembly

The BorgWarner 12647100008 is an EFR-7064 turbocharger cartridge assembly featuring a cast steel bearing housing. This is the core rotating assembly (CHRA) without turbine or compressor housings, allowing you to configure it with your choice of turbine housing options for custom turbo builds.

Key Features:

• 70mm forged-milled compressor wheel with 52.2mm inducer diameter and extended tip technology
• 64mm Gamma-Ti turbine wheel - titanium aluminide construction reduces inertia by approximately 50% for dramatically improved response
• Dual-row ceramic ball bearing assembly with metal cage for ultra-low friction and enhanced durability
• Water-cooled aluminum bearing housing with integrated oil control orifice (no external restrictor needed)
• Double seal design on both turbine and compressor ends for extreme durability and oil seepage resistance
• Cast steel bearing housing construction for enhanced strength

Performance Capability:

• 56 lb/min maximum compressor flow
• Supports 350-560 horsepower in single turbo applications
• 650-1000+ horsepower in twin turbo configurations
• Capable of 45+ PSI boost pressure

This cartridge assembly can be matched with various EFR-7064 turbine housings in T3 or T4 configurations with different A/R ratios to optimize performance for your specific application. The EFR series represents BorgWarner's flagship racing turbocharger technology, engineered for drift, road racing, and high-performance street applications where fast spool and maximum response are critical.
