Full-Race Electronic Wastegate Conversion Kit - BorgWarner B1 EFR

The Full-Race BorgWarner B1 EFR Electronic Internal Wastegate Conversion (eIWG) kit replaces traditional boost activated wastegate canisters with a powerful and reliable OEM electronic actuator (stepper motor).  Electronic actuators allow for precise control of the turbocharger wastegate in all conditions - opening the gate when you want it open, and closing the gate when you want it closed. 

The Full-Race eIWG actuator does not rely on boost pressure to operate properly. The actuator is fully controlled electronically. This type of control is much safer than older methods where a popped off wastegate boost reference line could lead to a blown engine. In addition to being safer, the level of control is much better. The actuator supports positions from 5-95% so that boost can be dialed in perfectly.  It also removes the need to worry about changing springs, solenoids, hoses and fittings.

Electronic internal wastegate controller kits are designed to make installation onto Borg Warner B1 EFR turbochargers as easy as possible. The kit includes all hardware to attach the bracket and actuator arm securely. The included pigtail wiring harness allows for easy connection to your choice of standalone ecu or our EWG-PRO wastegate controller.

The Full-Race eIWG bracket assemblies have been scientifically proven using finite element analysis to be significantly stronger than the comparable Garrett or Borg Warner wastegate actuator brackets. This means that the actuator assembly wont flex, ensuring accurate positioning leading to precise and predictable boost control

The Full-Race EWG-PRO Programmable Wastegate Controller can be paired with the eIWG Boost Control Conversion Kits for the ultimate in user-programmable control. If your ECU does not have an available H-Bridge output the EWG-PRO is fully capable as a standalone controller with a standard PWM output from your ECU.
