APR Presents the Stage III EFR7163 Turbocharger System for the North American 2.0T EA888 Gen 3 engine!
The APR Stage III Turbocharger System produces an incredible 522 HP and lays down 10-second quarter mile passes, all through a convenient, affordable and expandable, turn-key solution. It represents a threat to the establishment of turbo four cylinder vehicles of yesteryear, and breaks the hearts of muscle cars and exotics everywhere as they are left in the dust by an engine a third the size of theirs, screaming a turbocharged battle cry as it passes. It is a vicious beast, yet a beast easy to tame. It makes for a civilized daily driver that quietly sips premium fuel with surprisingly excellent mileage. Deceivingly quick transient response, with near stock-like turbo lag makes for an experience devoid of the compromises many would expect from an engine this size. It is the answer to the desire for more power, and it’s the brainchild of APR’s talented engineering teams, with over a year and a half of initial development, and a never ending drive for perfection. It is easy to install, blisteringly fast, and produces an absolutely exhilarating driving experience. Welcome to Stage III!

Included with the turbocharger system is APR’s world-renowned Stage III ECU Upgrade! This software upgrade installs on the factory ECU and requires no extra end user configuration or tuning and eliminates the need for costly piggyback controlling devices. Simply visit any APR dealer and the software installs in minutes!
APR’s Engineers spent more than a year and a half researching and developing the factory engine management system to operate seamlessly with the extensive changes introduced at Stage III. This includes thousands of full power sweeps on the engine and chassis dynos, street and track. This was no simple task as power is well beyond the original configuration with extensive hardware changes. Through both ECU source code and calibration changes, APR’s Engineers converted the system to run with a substantially larger turbocharger, featuring a pneumatic wastegate actuator and larger MAP sensors. At Stage III+ power levels, the software supports larger port injectors and a larger fuel pump.
Response, top end power, and reliability were all at the forefront of the Stage III turbocharger selection. Typically, these features do not go hand-in-hand. Larger turbos tend to be laggy, while small, responsive turbos lack top-end power. However, the Borg Warner EFR7163 has broken the mold. Featuring the latest advancements in technology, combined with APR’s advance tuning strategies, the ultimate in performance and reliability has been achieved!
The EFR7163 features a massive, 71mm forged-billet compressor wheel capable of outflowing the competition due in part to its extended-tip compressor geometry. By providing up to 60 lb/min in airflow, the turbocharger is capable of producing massive power and provides headroom for increasing output with future modifications.
To spin the massive compressor wheel quickly, the EFR7163 features a lightweight turbine wheel made from titanium aluminide, or Gamma-Ti, and feature new Mixed-Flow geometry. At nearly half the weight of conventional turbine wheels, the difference is extremely noticeable as transient response is lightning-fast upon smashing the accelerator! To further aid in low-end response without sacrificing top-end power, APR’s engineers built Stage III around the EFR’s optional T4 divided twin scroll turbine housing. This stainless steel housing is internally gated, making it the perfect solution for this application.
The turbocharger inlet and outlet hoses are designed with performance, strength, longevity, and total compatibility with all factory components. The hoses feature a multi-ply silicone design, which are internally lined with a flourosilicone coating. These materials were chosen to maximize performance, even under extreme conditions, and to protect against oil and gasoline degradation. Furthermore, at each connection point, the hoses use APR’s EZ-Flow stepped design to provide a port-matched surface transition, as it eliminates performance-robbing airflow disruptions associated with other designs.
The Borg Warner EFR Turbocharger’s outlet size differs from the factory turbocharger and as such, a new 3” V-Band downpipe is necessary and included. For customers with an APR Cast Downpipe Exhaust System, the included portion replaces the upper cast section and mates directly to the APR Catalyst Midpipe. For customers without an APR Cast Downpipe Exhaust System, the APR Catalyst Midpipe is available separately. The midpipe is fully compatible with the factory catback exhaust system.
To provide accurate closed-loop boost control through the factory ECU, new MAP sensors and mounting hardware are included. The ECU is recoded to fully work with the upgraded sensors, completely eliminating the need for clumsy and archaic stand-alone boost controllers. In doing so, the ECU retains control over the turbocharger and provides better daily drivability with increased safety.
The factory oil and coolant feed and drain lines are upgraded with new, application-specific lines that are designed to provide years of leak free operation. The braided stainless steel feed and drain lines come fully assembled and feature CNC mandrel bent hard-lines for clean and specific routing as if intended by the OEM. Both o-rings are replaced and a Borg Warner gasket is included.
No invasive cutting or splicing of the factory wiring harness is necessary as new MAP sensor, wastegate solenoid and DV extension harnesses are included. Each harness comes fully assembled for a simple plug and play install.
All install hardware is included for a complete install. This includes Loctite, assembly lube, an exhaust v-band clamp, Clampco T-Bolt clamps, worm gear clamps, Oetiker clamps, OEM spring clamps, turbo support bracket, Borg Warner and OEM gaskets, low-profile banjo bolts, copper crush washers, copper lock nuts, nuts, washers, bolts, studs, MAP sensor install tool, boost tap cap, various heat shielding materials and a zip-tie.
The APR Fueling System is a comprehensive upgrade required to safely support Stage III+ power levels. The upgrade includes a larger in-tank low pressure fuel pump (LPFP) and adds multi-port injection (MPI) to the factory manifold, both of which are ethanol compatible. All necessary hardware is included for a seamless integration and the system is fully controlled by the factory engine control unit (ECU) thanks to APR’s ECU Upgrade.
