Borg Warner EFR Series 6758 Turbocharger
The EFR 6758 is a versatile turbocharger 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. Ideal for use in single turbo applications for the 300-490hp range, or as twin turbo applications 550-900+hp. Ceramic Ball Bearing only, watercooling recommended (not mandatory).
