GTxxyyzz:

Positions "xx" refers to the frame size of the turbine wheel inducer.
For example the "GT28" in "GT2860RS" refers to its turbine wheel frame size family. All GT28 units use a turbine wheel with 53.85mm inducer diameter
As a rule of thumb, the larger the number, the larger the turbine wheel.
Positions "yy" designate the compressor wheel exducer (major) diameter in millimeters
The "60" in the GT2860RS example above has a 60mm compressor wheel exducer diameter.
Note: Wheel sizes 100mm and over omit the "1" (hundreds digit)
Example: the 02 in a GT4202 refers to its 102mm compressor wheel exducer diameter
Positions "zz" may be used to designate special features of a particular turbocharger where applicable mostly on garretts its the Trim.
Example: GT2860RS
"R" = this is a Ball Bearing unit
"S" = used for units which require some differentiation from units in the same family
Compare a GT2860R to a GT2860RS. While both are ball bearing and externally similar, the GT2860RS is better suited for higher-flow applications than the GT2860R. In this case, the S reflects the higher-flowing nature of the GT2860RS

There are some good articles on garrets website about it all
