noob question about dsm turbos

can someone explain to me how you read a dsm turbo?
i just bought a turbo off a 98 gsx for my civic and wanted to know what size it is, what is the smallest to biggest dsm turbo? i know it goes somethin like t25, t28, g16, g18?, b14, b16?, b18?

The "t" in t25&t28 is trim, am i right? well how do you read how big the g and b is? and how big is the flanges on these turbos? are any of them t3's?

a 98 GSX came with a t25 turbo

real quick like explaination:

t25 = stock 95-99 turbo on GST, GSX

t28 = upgraded t25 but very expensive

13g, 14b, 16g, 18g, 19c, and 20g are all Mitsu turbo's.

the b16 and b18 are hondu engines...
