BorgWarner EFR7163 .80 A/R T4 Turbo

Borg Warner EFR 7163 is an excellent turbocharger for drift, road racing and street driven applications. The 7163 delivers incredibly fast spool and response while working well on stock and heavily modified engines. The 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. Ceramic Ball Bearing only, watercooling mandatory
