Your Turbo Nameplate
A nameplate will vary according to whether it relates to an original equipment turbo installed by the vehicle manufacturer or to a turbo bought through the independent Aftermarket. The nameplate shows a customer or Garrett part number, turbo model and serial number – providing you information that might help you order a replacement turbo.
See photos of nameplate examples of OE turbos and replacement turbos.
· Details engraved directly onto the nameplate pad or onto a separate nameplate, which is then bonded on top of the original factory nameplate.
· Note: you may see Garrett, Garrett AiResearch, AlliedSignal, Garrett Engine Boosting Systems or Honeywell logos on older turbos.
Typical IAM nameplates: · Do not include OE logo or OE name
· Do include:
– Turbo model
– Country of Origin
– Part number in IAM format
– Serial number

Turbocharger Identification
Part Numbering
All part numbers have 6 digits, starting either with 4, 7 or 8.
Examples: 466214, 700447, 801040. Variations of that part number have a “-” followed by four numbers and possible suffix letters. This is referred to as “the dash number” and informs the reader how the turbo was supplied:
Some Examples | |||
---|---|---|---|
OEM | new turbo | 700447-0008 | First character of dash number always 0, no suffix |
OES | new turbo | 700447-5008 | First character of dash number always 5, no suffix |
new turbo | 700447-0008S | No longer used, but may exist on older turbos | |
IAM | new turbo (may include gasket kit – check website) |

T Series and GT Series
Garrett T Series was the original turbo designation beginning in the 50s. T-Series turbos tend to have more parts, be larger in size, and represent early-generation technologies. Garrett GT Series first came into being in the early 90s, and they feature newer aerodynamic design, advanced design with fewer parts, and better overall performance.
