In the old TOYOTA turbos, the turbo part number comes with a sticker stuck to the turbo actuator, although in the present turbos it is placed on the compressor housing.
In the case that the sticker is lost or missing you must try to identify the turbo searching for the part number inscription on the turbine housing, this is a 5 digit number like 54030 (Note: This is not the turbo part number, just the number of the turbine housing.) Contact us with the turbine housing part number and we will try to identify the turbo.
