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 โ providing you information that might help you order a replacement turbo.
See photos of nameplate examples of OE turbos and replacement turbos.
ยทย Note: you may see Garrett, Garrett AiResearch, AlliedSignal, Garrett Engine Boosting Systems or Honeywell logos on older turbos.
Typical IAM nameplates:ย ยทย Do notย include OE logo or OE name

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.
