To make sure you order the correct replacement turbocharger you will need to know the turbo part number. Alternatively, we can use your registration vehicle number to identify the turbo part but this is not always enough.
Here is a list of the most common turbocharger manufacturers and how to find their turbo part numbers:
Garrett / Honeywell
Garrett Honeywell turbo part numbers are located on a plate or etched into a small rectangular machined area on the aluminium compressor housing. Typically, the number consists of a 6 digit number (xxxxxx) followed by a dash ( – ) then 4 numbers, later versions will also have a suffix following the last 4 digits (xxxxS). Part numbers will usually start with 4, 7 or 8. (eg: 7xxxx0 -5xx3S)
Other numbers will be visible on the ID plate. These will be Vehicle manufacturer / OEM (Original Equipment Manufacturer) part numbers and build serial numbers.
Numbers that you may see are the turbo frame type ie: GT1749V. This indicates the turbo type, not the turbo part number.
IHI
Turbo part numbers are usually engraved or stamped into a rectangular ID pad on the compressor housing of the turbo, similar to Garrett. Usually 4 digit Alpha / Numeric Specification number (eg: VF50 ). IHI generally use the second digit ( F ) to identify vehicle or engine manufacturer. In this case, “F” refers to Subaru.
Other numbers will be visible on the ID plate. These will be Vehicle manufacturer / OEM part numbers and build serial numbers.
