Borg Warner EFR 6758 Turbo (275-450 HP)

"The Borg Warner EFR 6758 turbo is the 3nd size (#3 of 7) turbocharger in the high performance EFR series. The 6758 is a versatile turbocharger with large map width for outstanding power potential even at high boost and does it in a small package. Uses the same compact compressor housing found on it's younger brother but with a larger 53.9mm inducer, 67mm exducer compressor wheel to support a remarkable 49lb/min max flow rate & up to 450 HP. Very quick spool makes it the perfect choice for small engines in single turbo configuration or lager engines in twin form for up to 900 HP. Neck napping fast spool/response, compact & impressive HP yield thanks to it's FMW compressor wheel, Gamma-Ti turbine wheel & dual row ball bearings. This is also an excellent turbocharger for rally, drift, road racing, auto X, street applications & even 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.
