The EFR 6258 is the smallest and fastest spooling EFR turbocharger in the lineup. Ideal for small engines in single OR twin turbo configuration, this is an excellent turbocharger for autocross, rally, drift, road racing and street driven applications. The 62mm OD compressor has a 49.6mm inducer rated at 44lb/min max flow - supporting up to 440hp. This compressor wheel is versatile with very large map width for outstanding power potential, even at high boost. The low inertia 58mm Gamma-Ti turbine wheel is optimally matched for maximum response and fast spool with the FMW compressor wheel. EFR 6258 uses the smallest-sized EFR compressor housing, making fitment in the tightest engine bays possible. Ideal for use in single turbo applications for the 260-440hp range, or as twin turbo applications 400-700+hp **will not shuffle in twin turbo configuration like twin garretts** Ceramic Ball Bearing only, watercooling recommended.
