16g Identification??

I Have searched and I cannot seem to find how do you identify an 16g turbo. What I mean by this is how do you tell the difference between the 14b and 16g?

thank you, helps me out a lot, thank you

 

There is a thread "visual 16g identification" that has some good information in it also. I would link it but for some reason it isnt working right. just go to the search and type in "visual 16g identification" with quotation marks and it should come up.
