Turbo sizes between APS and GTM?

I'm confused as to how there's all this incorrect information in here when a visit to Garrett's website would give you more correct information than you can shake a stick at.

Garret has a way of numbering their turbo part numbers in such a way as to let you know what the exducer size of the compressor is. So, in GT2554R, the 54 refers to the exducer size of the compressor wheel. Naturally, GT2860RS means that it has a 60mm exducer which is bigger than a 54mm exducer.

The first pair of numbers in their numbering system refers to the frame size of the turbo. The bigger the number, the bigger the turbo is. As such, a GT25 is smaller than a GT28.

In short, our Stage 2 turbos are bigger than the old, discontinued, no longer available APS kit for the 350Z.
