Identify your
Turbocharger
Garrett
Look for 'Garrett' embossed on the compressor housing with a unique identification number. This number, usually beginning with 4, 7, or 8, reveals your turbo's series and specific features. Example: 794786-0001, where 794786 identifies the model and 0001 indicates the series.
Borgwarner
The identification number on these units is a series of numbers. These numbers follow a 4-3-4 pattern, with the first and last series of numbers denoting the turbo’s model and the middle representing the series number. These numbers are usually etched onto a blue tag, which is usually attached to the compressor housing (the aluminium snail-like top lid of the turbo). Dashes do not separate the numbers on the tag. As the example photograph shows, the numbers are listed as 53049700064. When placed into the 4-3-4 pattern, this turbo's identification number is 5304-970-0064.
Occasionally, Borg Warner only gives the last four digits instead of the whole number (for example, 0064). In this instance, you may need to refer to the chart below to identify the first seven numbers. These can be determined using the code to the left of the identification number (K04 in the example photo).
K03 = 5303-970-_____
K04 = 5304-970-_____
K14 = 5314-970-_____
KP35 = 5435-970-_____
KP39 = 5439-970-_____
BU39 = 5439-970-_____
BU50 = 5304-970-_____
The figures in the middle series may differ; common numbers include 970, 988 and 998, but this has little relevance in terms of identification as the first and last four digits of the ID number are the most important

Mitsubishi
Mitsubishi uses a ten-digit code to identify their turbochargers. These follow a 5-5 pattern and usually begin with the number four. The first five digits denote the series of turbo and the last five identify the model. Both sets of numbers are separated by a dash. In the example photo, the number is 49135-05132.
IHI
The identification numbers on these models usually combine a short series of letters and numbers, typically beginning with a 'V'. The photo example is of a VT10. There are numbers following the first section which denote the series, but these are less important than the first alphanumeric section.
The turbo’s ID is etched and can sometimes be difficult to see. If you're struggling to distinguish the identification code you can improve the visibility of the digits by driving dirt into the indentations of the etching using oil on your finger or a cloth.
