How to identify your Turbocharger?
All turbochargers should have an identification label or nameplate secured to the outside casing of the turbocharger. It is preferable if you can supply us with this make and part number of the actual turbo fitted to your car.
Normally, you can identify the turbocharger by Model Name, Part Number and OEM number.
This generally indicates the general size and type of the turbocharger.
The specific part number of a turbocharger is assigned by the turbo manufacturers within a range of turbochargers. This specific part number can be used to identify the turbocharger straight away, so usually it is recognized as the best form of turbo identification.
Customer Number or OEM Number:
OEM number is assigned by a vehicle manufacturer for a specific turbocharger of a vehicle. Please note that performance turbochargers for generic use do not have an OEM number.
There are several manufacturers of turbochargers, which include Garrett, KKK, Borgwarner, Mitsubishi and IHI. Below are guides to help you identify where, in each case, you can find the part numbers which ideally, we require.
1.Garrett Turbocharger (Honeywell)
The part number of a Garrett turbocharger comprises six digits, a dash and more digits i.e. 723341-0012 This number can usually be found on the aluminium compressor housing of the turbocharger, either on a 2-inch plate or on the cover itself and normally consist of numbers that start with a 4, 7 or 8.

2.KKK Turbocharger (BorgWarner / 3K)
KKK or Borg Warner are more difficult to find. The part numbers are again usually located on the compressor housing (or in some instances on the underside near where the oil/drain pipes go) on a small plate. They also have the biggest range of part numbers and variations used so it can be a little more difficult.

K04-0020, 5304 970 0020, 5303 988 0020

Holset use the assembly number as the part number, they also usually start with a 3, the turbo type can also be useful when trying to narrow down a Holset turbo to application.
