BorgWarner 12641008006 B2 64mm Turbine Housing 0.83 A/R T3 Internal Wastegate

The BorgWarner 12641008006 is a precision-engineered B2-frame turbine housing designed for the EFR (Engineered For Racing) 7064 series turbochargers. This high-performance turbine housing features a 0.83 A/R ratio with a T3 inlet flange configuration and single-scroll design with an integrated internal wastegate.

Key Features:

• B2 frame size for 64mm turbine wheel compatibility
• 0.83 A/R (Area/Radius) ratio optimized for balanced spool and flow
• T3 single-scroll inlet flange for simplified exhaust manifold integration
• Internal wastegate (IWG) configuration for boost control
• Investment-cast stainless steel construction for superior durability and corrosion resistance
• V-band outlet flange for secure, leak-free connection
• Compatible with BorgWarner EFR 7064 super core assemblies

This turbine housing is a critical component for building custom EFR 7064 turbocharger configurations, supporting power levels from 300 to 550 horsepower. The 0.83 A/R ratio provides excellent throttle response and quick spool characteristics, making it ideal for drift, road racing, and performance street applications. When combined with the appropriate EFR super core, this housing creates the complete 179355 turbocharger assembly.
