Borg Warner 6758 EFR Turbo, 250-500 HP. The Borg Warner 6758 EFR Turbo is a versatile turbo with very large map width for outstanding power potential even at high boost - and does it in a small package. This is an excellent turbocharger for autocross, rally, drift, road racing and street driven applications. This turbo uses a 67mm OD compressor with a 53.9mm inducer to support a remarkable 49lb/min max flow rate. The low inertia 58mm Gamma-Ti turbine wheel is the optimal match for the FMW compressor wheel. EFR 6758 uses the smallest-sized EFR compressor housing, fitting in the tightest engine bays particularly twin turbo V6 or V8 applications. In twinscroll T4 configuration, the 6758 delivers mindblowing fast spool and response while working well on stock and modified engines. Ideal for use in single turbo applications for the 250-500hp range, or as twin turbo applications 500-1000+hp. Ceramic Ball Bearing only, watercooling recommended (not mandatory).
Borg Warner's latest release, the EFR (Engineered for Racing) Series turbochargers. EFR is currently the most advanced turbo of its type engineered for the performance aftermarket. Crammed full of attributes that appeal to the performance car enthusiast, EFR is at the pinnacle of what can be done with the current state of the art.
The result is the new EFR (Engineered for Racing) line of turbos from BorgWarner. These turbos contain a bevy of key attributes such as Gamma Ti turbine wheels, dual ceramic ball bearing cartridges and investment cast stainless steel turbine housings. Collectively, those features help give the EFR line its innovative appeal and will provide a breakthrough experience in durability, device responsiveness and installer/user satisfaction.
