The EFR 7163 71mm OD compressor has a 57mm inducer and there is potential for 550hp – unheard of for this size compressor wheel. The low inertia 63mm Gamma-Ti turbine wheel is the optimal match for the 71mm FMW compressor wheel and is capable of 45+psi boost. This turbo uses the mid-size EFR ported-shroud compressor housing, great for fitment in cramped engine bays. Ideal for use in single turbo applications for the 300-550hp range, or as twin turbo applications 650-1000+hp.
