Internal Wastegated The Borg Warner EFR 7064 is the 4th size (#4 of 7) turbocharger in the high performance EFR line up. The 52.2mm inducer, 70mm exducer Fully Machined Wheel (FMW) compressor flows 56lb/min & will support 500 HP. Truly remarkable for a wheel of it's size. Extremely quick spool & high HP output in a compact frame size. Unrestricted 3.50" air inlet, 2.00" slip-on coupler outlet with integrated Vband option allows use of a standard silicone connector or burst-proof V-band flange & clamp. The BW EFR 7064 is suitable for rally, drift, road racing, auto X, street & drag.

BorgWarner EFR (Engineered For Racing) Series turbos are purpose built units for the performance market & meet the needs of the next generation turbo consumer. Revolutionary from the ground up, each incorporates a long list of features never before seen in a single package. All old technology has been thrown away completely & the result is a whole new breed of turbo, packed full of cutting edge advancements. Great emphases has been put towards a more compact design, making each EFR the ideal choice for applications with limited space available. Outstanding ease of installation & budget friendly (thanks to their 'total package' platform) every EFR eliminates the need to purchase/fabricate/install a separate blow of valve & related flanges/tubing due to their already integrated BOV. The internally wastegated units present another large advantage in savings & install simplicity by eliminating the need for an external wastegate(s), related fab work & otherwise cumbersome materials.
