Borg Warner EFR Series 7064 TurbochargerEFR 7064 is an excellent turbocharger for drift, road racing and
street driven applications. The 7064 delivers incredibly fast spool
and response while working well on stock and heavily modified
engines. The 70mm OD compressor has a 52.2mm inducer and at 56lb/min
max flow - there is potential for 560hp - unheard of for this size
compressor wheel. The low inertia 64mm Gamma-Ti turbine wheel is the
optimal match for the 70mm 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 350-560hp range, or as
twin turbo applications 650-1000+hp. Ceramic Ball Bearing only,
watercooling recommended (not mandatory)
