How to identify a turbo

There are several manufacturers of original turbos. These include Garrett, KKK, Borgwarner, Mitsubishi, Holset and IHI. Below are guides to help you identify where, in each case, you can find the part numbers which ideally, we require.

GARRETT

A Garrett part number consists of 6-digits. Followed by a dash (-) and then more digits. Please see below some examples:

708639-0001

753420-0002

454135-5001S

The part number is usually located on the alloy compressor cover of the turbocharger. There is usually a smooth, 2-inch plate where the number is located or sometimes printed into the compressor cover itself. There will be a number of characters located on the plate. Usually the Manufacturers’ part number, OEM number and Model Number will all exist.

KKK / BORGWARNER TURBO SYSTEMS

KKK or Borg Warner are more difficult to find. The part number is found on the alloy compressor cover of the turbo and will be on a small KKK plate. An example of a KKK part number are as follows:

K03-0053, 5303 970 0053, 5303 988 0053

K04-0020, 5304 970 0020, 5303 988 0020

KP35-0005, 5435 970 0005, 5435 988 0005

KP39-0022, BV39-0022, 5439 970 0022, 5439 988 0022

Having 970 or 988 just means the part is a Turbocharger.

MITSUBISHI TURBO SYSTEMS

Mitsubishi part numbers have a 5-digit prefix, followed by a dash (-) and an additional 5-digits, for example: 49377-03041.
