All turbochargers must have an identification tag or nameplate secured to the outer casing of the turbocharger. It is preferable if you can offer us the make and part number of the actual turbo installed in your car. Typically, you can identify a turbocharger by model name, part number, and OEM number.

 

Model Name:This generally indicates the overall size and type of the turbocharger.

Part number: The specific part number of a turbocharger is assigned by turbocharger manufacturers within a range of turbochargers. This specific part number can be used to identify a turbocharger immediately, which is why it is generally recognized as the best way to identify the turbo.

Customer number or OEM number: The OEM number is assigned by the vehicle manufacturer for a vehicle-specific turbocharger. Note that generic performance turbochargers do not have an OEM number.

 

There are several manufacturers of turbochargers, including Garrett, Borgwarner, Mitsubishi, and IHI.

Below you will find guides to help you identify where, in each case, you can find the part numbers that we ideally need to identify the turbocharger.

1. Garrett Turbocharger (Honeywell)

The part number for a Garrett turbocharger comprises six digits, a dash, and more digits IE 7 23 341 -00 12 This number can generally be found on the turbocharger’s aluminum compressor housing, either on a 2-inch nameplate or on the lid itself and usually consist of numbers starting with a 4, 7 or 8.

 

EXAMPLES:

723341-0012

708639-0001

801374-0003

 

Garrett Part Number: 723341-0012

Manufacturer OE : 4U3Q6K682AJ

2.BorgWarner turbocharger

Borg Warner are harder to find. The part numbers again are usually found on the compressor housing (or in some cases on the bottom near where the oil / drain lines go) on a small plate. They also have the largest variety of part numbers and variations used so it can be a bit more difficult.

 

EXAMPLES:

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, 5439970 0022, 5439988 0022

 

BorgWarner Part Number: 5435-988-0002

Note: 988 can be interchanged with 970 and may be required when searching in store.

3.Mitsubishi turbocharger

The Mitsubishi turbocharger has a 5-digit prefix followed by a dash, then a 5-digit suffix, and often starts with a4. In most cases, they are identified by numbers etched into the machined flat face of the alloy inlet compressor casing.

 

Examples:

49377-03041

49135-05671

49335-01000

49131-0521 2

 

Mitsubishi Part Number: 49131-05212

Manufacturer OE : 6U3Q6K682AF

4. IHI turbochargers

IHI use the Turbo Spec as the turbocharger part number, they generally use 4 characters, usually two letters and two numbers or 4 letters. The part number can be found on the turbocharger compressor alloy cover.

 

Examples:

VJ 60

VJ36

VV14

VIFE

VIFG

 

IHI part number: VA60

Manufacturare OE : 35242052F

5.Holset turbochargers

Holset uses the assembly number as the part number, they usually start with a 3 too, the turbo type can also come in handy when it comes to reducing a Holset turbo to application.

 

Example:

3788294

3597179

3539502

4040250

 

Holset Part Number: 3 533544

Turbo type:HE500FG
