| GT20, GT22, GT25 | Medium diesels in cars and vans | Actuator fitted |
| GTB, GTD | Newer generations with improved compressor stage | In demand |
| GT30 to GT45 | Trucks and industrial engines | Flanges undamaged |

Reading the Garrett type plate
The type plate sits on the compressor housing. It carries the Garrett part number, usually six digits with a variant suffix (for example 724930-5010S), the model designation (GT1749V) and the engine manufacturer's OE number. The six-digit number identifies the turbocharger unambiguously; the suffix after the hyphen distinguishes revisions. If the plate is illegible, the casting number on the turbine housing together with the engine details helps.

- Shaft turns, compressor wheel may be damaged
- VNT actuator fitted, even if faulty
- Not dismantled, core assembly in the housing
- Flanges not cut off, oil ports undamaged
Typical rejections
- Turbine housing with a heat crack through the flange
- Turbochargers without actuator
- Dismantled turbochargers without core assembly
- Sawn-off exhaust flanges
Frequently asked questions
Do you also buy Garrett turbochargers with a broken shaft?
Yes, as long as the housings are intact. The core assembly is replaced during remanufacturing anyway.
Are Garrett turbochargers from trucks in demand?
Yes, especially the larger series from commercial vehicles and industrial engines.
