BorgWarner EFR 7670 Turbo

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.
