Original BorgWarner EFR Cartridges are a low-cost way to rebuild an EFR Turbo. In the past you always have to buy a new Super Core, which included a new compressor housing. But normaly only the bearings or a turbine / compressor wheel is damaged. Now we offer you as official BorgWarner Performance Distributor exclusive EFR cartridges (CHRA).
Notice: When ordering only an EFR CHRA, be sure to check if your compressor and turbine housing has no damages, like scratches or cracks inside. Only when your compressor and turbine housing is in good condition, then a new cartridge make sense. Otherwise you need a Super Core or a complete new turbo! The mounting kits for the turbine and compressor housing, the EFR CRV, solenoid, vacuum hoses, actuators, as well as the exhaust gas and compressor housing itself is always required. If the turbine housing has a wastegate flap, you also need an internal wastegate actuator and a suitable holding plate.
