The BorgWarner EFR 6758 B1 Series Super Core (MPN 179375) is the core assembly of choice for builders seeking elite transient response and mid-range power. As a Super Core, this package includes the complete center housing rotating assembly (CHRA) and compressor housing, allowing you to select the specific turbine housing (A/R and flange) required for your custom manifold setup. Gamma-Ti Turbine Wheel: Constructed from Titanium Aluminide to drastically reduce rotational inertia, providing near-instantaneous boost response. Forged Milled Compressor Wheel (FMW): Features a 53.9mm inducer and 67mm exducer, engineered for high-pressure efficiency and durability. Dual Ceramic Ball Bearings: Offers minimal friction and high load capacity for improved spool and long-term reliability under racing conditions. Integrated Components: Equipped with a built-in Compressor Recirculation Valve (CRV) and Boost Control Solenoid (BCS) to simplify plumbing and reduce engine bay clutter. Technical Specs: B1 frame size; 58mm turbine wheel; includes speed sensor port and pre-machined mounting points. Designed for the EFR (Engineered For Racing) line, this 6758 Super Core replaces worn units or serves as the heart of a new high-performance forced induction system.
