more turbo options

still trying to wrangle up a turbo that works well on the 4bd1t. in looking at more, I end up with a ton more questions. any help is appreciated to understand the nomenclature of what seems to be the most important, and most complicated component of performance!

T3 - does this only refer to the exhaust mount?
T25 - this refers to the core size?
TB2522 - this turbo specifically as an example, how does this compare to the stock 4bd2t, or the nissan bluebird t25?

A/R numbers - this area to radius ratio, is it just comparitive, or does it relate to Mass air flow, or MAP?

from ebay...
This is a genuine Garrett T25 turbo. It is brand new. It's Garrett P/N 465749-5001. The Turbine A/R is .49. Compressor A/R is .48 This was the OE turbo used on Pontiacs in the late '80's. It has the same specs as the stock CA18DET turbo other than it uses different oil and water connections. It is good for about 225 HP.
