Turbo Identification - How to identify your Turbocharger?

Can you speak turbo? The information on a turbo housing nameplate will help you specify the exact replacement turbo you need and will also reveal the key components that make each turbo so special.

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 on the nameplate.

There are several manufacturers of turbochargers, which include Garrett, Borg Warner, 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 Turbochargers

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.

Example:

Garrett Part number: 723341-0012

Manufacturer O.E: 4U3Q-6K682-AJ

2. Borg Warner Turbochargers

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.

Example:

BorgWarner Part number: 5435-988-0002

Note: 988 can be interchanged with 970 and might be required when searching the store.

3. Mitsubishi Turbochargers

Mitsubishi turbocharger have a5 digit prefix followed by a dash then a 5 digit suffix and often start with a4. They are in most instances identified by numbers engraved into the flat machined face in the alloy inlet compressor housing.

Example:

Mitsubishi Part number: 49131-05212

Manufacturer O.E: 6U3Q6K682AF

4. IHI Turbochargers

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

Example:

IHI Part number: VA60

Manufacturer O.E: 35242052F

5. Toyota Turbochargers

Toyota can be very confusing indeed to identify, with some units not even carrying any ID plates at all. Usually the most easily accessible turbo number is 5 digit number which is located on the turbine housing where the turbocharger connects to the manifold.

Example:

Toyota Part number: 17201-74040

6. Holset Turbochargers

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.

Example:

Holset Part number: 3533544

Turbo Type: HE500FG

However, how do you identify your turbocharger if the tag is missing?

If the turbocharger name plate is missing or difficult to read, you can send us the VIN number or chassis number to check.
