BorgWarner EFR 7064 Turbo

The BorgWarner EFR 7064 Turbo Is Built for Road Racing, Auto-X and Drift

The BorgWarner EFR 7064 is an excellent turbocharger for drift and road racing 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 and 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 delivering 45+psi of boost. This turbo uses the mid-size EFR ported-shroud compressor housing, and with the T3 turbine housing it's a direct fit for Nissan RB20/25 engines. Ideal for use in single turbo applications for the 350-500hp range, or as twin turbo applications 600-1000+hp. This turbo is ceramic ball bearing only and watercooling is optional but recommended.

Why We Love it:

This is the smallest and fastest spooling "B2" mid frame turbo in the EFR family.  Using their low inerta and low backpressure 64mm turbine in the B2 housings allows for a broad range of applications targetting the 350-500hp per turbo.  Extremely popular for Nissan RB20 & RB25 (direct fit plug and play) as well as Cosworth YB engines
