Product Description

Borg Warner's latest release, the EFR (Engineered for Racing) Series turbochargers. EFR is currently the most advanced turbo of its type engineered for the performance aftermarket. Crammed full of attributes that appeal to the performance car enthusiast, EFR is at the pinnacle of what can be done with the current state of the art.

The EFR line of turbos was born out of an internal BorgWarner Turbo Systems program labeled Advanced Aftermarket Products or AAP.

The program was engineered by a cross-functional team that began with the proverbial clean-sheet of paper. No legacy products, no preconceived notions of what a turbo could or could not have; no restrictions. The aerodynamics for the product line were selected using a range of optimized combinations that would give users turbo solutions anywhere between 250 and 1000 horsepower capability per turbo. Next, a list of every notable design characteristic for an engine boosting device was tabled. Specific interest was given to new ideas that had never been formed in metal or had never been combined into an aftermarket turbo.



The result is the new EFR (Engineered for Racing) line of turbos from BorgWarner. These turbos contain a bevy of key attributes such as Gamma Ti turbine wheels, dual ceramic ball bearing cartridges and investment cast stainless steel turbine housings. Collectively, those features help give the EFR line its innovative appeal and will provide a breakthrough experience in durability, device responsiveness and installer/user satisfaction.

Borg Warner Turbo Sizing Map
The map below shows the inducer and exducer sizes in millimeters. Precision and Turbonetics follow a different terminology than Borg Warner. Borg Warner denotes the exducer of the compressor and inducer of the turbine, while Precision denotes the opposite. So to get a better understanding of similar turbos, we have highlighted the bold #'s for comparison to the Precision line up of turbochargers. 

For instance, Precisions turbo 6262 would be closely related the Borg Warner 6264. Being that the Borg Warner's turbine wheels are made from Titanium and are half the weight of Turbonetics Precision and Garrets Inconel wheels, you can afford to have a bigger turbine wheel 64mm compared to 62mm because it will spool up quicker and be able to eat more exhaust gasses. Turbine wheels are the main factor in limiting HP, so with the same size compressor wheel, the Borg Warner units are able to support more HP than their competitors, while spooling even quicker!
