Cartridge BorgWarner EFR-7163
Original EFR rump group - 11637100000
Cast steel bearing housing, turbocharger without exhaust gas housing and compressor housing
The trunk assemblies can be combined with any turbine housing for this turbocharger. This is particularly useful if the desired configuration of the turbocharger with the desired turbine housing is not available for direct purchase, or if you want to use an turbine housing from a third-party manufacturer. In addition to the core assembly, the mounting set for the exhaust housing and the exhaust housing itself is always required. If the turbine housing has a wastegate flap, you will also need a wastegate and a suitable retaining plate.
Power range: 225 - 550PS
Compressor wheel Inlet: 57mm, outlet 71mm
Turbine wheel Outlet: 63mm
Exhaust housing : not included
Compressor housing: Not included
