BorgWarner EFR 6758

The BorgWarner EFR 6758 turbocharger represents the perfect balance between fast spool-up and greater airflow compared to the EFR 6258. It is designed for projects targeting 300 – 550 HP while maintaining extremely fast throttle response, making it one of the most popular EFR models for street and competitive applications.

Features:

Turbine wheel made of Gamma-Ti (Titanium aluminide) superalloy – very light, allows for extremely fast turbine response

67 mm compressor wheel (FMW – Forged Milled Wheel) with high flow and optimized aerodynamics

Dual-row ceramic ball bearings – minimal friction, long service life, suitable for high boost

Integrated blow-off valve, boost solenoid, and compressor speed sensor port

Multiple turbine housing options: T25, T4, or V-Band, with various A/R ratios for optimal engine matching

Recommended for engines with displacements of 1.6 L – 3.0 L (single turbo) or as part of a twin-turbo system on larger engines

Advantages:

Fast spool-up with higher flow than EFR 6258 – ideal compromise between response and power

Built-in components reduce the need for additional equipment and simplify installation

Suitable for street, track day, drift, and endurance vehicles

Exceptional thermal resistance and stability at high boost pressures
