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
Quer com isso dizer, que tens a compressora de um GT1852v de um mercedes?
