BorgWarner EFR 7670 Turbo (12769097001)
BW’s EFR 7670 is ideal for responsive street driven vehicles as well as road racing and time attack applications. EFR7670 delivers early spool with a healthy 64lb/min compressor flow.
BW utilizes their 70mm Gamma-Ti turbine wheel as the optimal match for the 57.2mm inducer / 76mm exducer FMW compressor for unmatched response. This turbo uses the mid-size EFR ported-shroud compressor housing, great for fitment in cramped engine bays. An excellent fit for use in single turbo applications for the 400-600hp range (up to 2.6L), or as twin turbo applications 800-1200+hp. Ceramic Ball Bearing only, watercooling recommended.
