Borg Warner 6258 EFR Turbo, 225-450 HP. Borg Warner 6258 EFR Turbo is the smallest turbocharger in the ultra-efficient EFR lineup. The 62mm OD compressor has a 49.6mm inducer at 44lb/min max flow - supporting up to 450hp with very large map width for outstanding power potential even at high boost. The Borg Warner 6258 EFR Turbo is the fastest spooling EFR turbo - and fits in a small package. Ideal for small engines in single turbo configuration and stock internal or modified engines. This is an excellent turbocharger for autocross, rally, drift, road racing and street driven applications. The low inertia 58mm Gamma-Ti turbine wheel is optimally matched for maximum response and fastest spool with the FMW compressor wheel. EFR 6258 uses the smallest-sized EFR compressor housing, fitting in the tightest engine bays particularly twin turbo V6 applications. Ideal for use in single turbo applications for the 225-450hp range, or as twin turbo applications 400-700+hp. Ceramic Ball Bearing only, watercooling recommended (not mandatory).
