The Borg Warner EFR 6758 (179388) 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. In twin scroll T4 configuration, the 6758 delivers mind blowing fast spool and response while working well on stock and modified engines. 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.
