930 is not a 911 generation number, it's strictly a 911 Turbo of that generation! You found 3 pictures of 930, but non-turbos didn't necessarily have a whale tail and wide wheel arches.
Strictly speaking 901 isn't valid either, it's just a name that the car had before it was renamed to 911. But I'm letting it slide because it was called 901 at the beginning and it's the same body type
Well, if you want to be really

I usually refer to all 911s from 0-series to the G-series as 901 body style, then from there on I just use 930 (optionally SC or Carrera if I know) for everything after to the last Carrera of 1989. 930 doesn't always designate a Turbo though, only a body style (flared wheel arches and whale tail wing) for instance all of the 911 Speedsters (not the 964s, obviously) made were 930 bodied, and the "Turbo look" (wide arches and whale tail wing w/o intercooler box) is also a common sight, as that, if my memory serves me correctly, was a factory option on the SC for a while.
