I can't believe how much Honda stuff is on the Honda forums with little to no concise info.
After much digging I found some info that seemed factual.

Info from:
http://www.ozhonda.com/

So I have a Civic 92-95 = EG Si which has a 7/8" master.
Civic DX/LX/VX/CX/Si (Si non-abs) < (Civic EX = Civic Si ABS), an Si has a 9"/9.5" (pending on who you ask) rotor.
Where as EX has a 10.3" rotor and a Type R has 11.1"

There are at least four Brake Master Cylinder sizes as follows:
Civic ex/si - 7/8" (22.2250mm)
Civic others - 13/16" (20.6375mm)
Civic ABS - 7/8" (22.2250mm)
Integra - 15/16" (23.8125mm)
ITR - 1" (24.5mm)

My diameter size is 7/8.
Which matches 92-95 Honda Civic Ex or Si with diameter size of 7/8...

There are at least six models of Brake Booster as follows:
NM205V
NM230V <- Mine
NM240V
NM260V
NM280V
NM290V

46100SH4A11 = Si Model; Bore: 15/16" (92-95 Civic EG with a standard 7/8 MC then a 15/16" m/c can be fitted without needing to upgrade the booster or redo the hardlines) - 90-91 civic ex 4-door?

46100SH3A02, 46100SH3A03, 46100SH3A04, 46100SH3A05, 46100SR3003, 46100SR3013, 46100SR3033} = EX Model; Si Model;

- Clean the piston










- Bleed the MC






New booster is smaller in diameter










But thicker.










It was cheaper to get a 2nd hand master and booster.  This is 15/16", slightly bigger. Plus it was described as double boosted, booster.
