Your Turbo Name Plate

A name plate 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 name plate 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 name plate examples of OE turbos and replacement turbos.

· Nameplates may vary according to geographic region, assembly plant and local requirements.
· 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

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, 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.
