Which booster? Gen 3 brakes

Hey all,
 
Currently in the process of changing my whole braking system over to Gen 3 Turbo non ABS system. 
 
I have (or am getting) 93+ rear calipers (22v), 93+ front calipers (36T30), 93+ non ABS 15/16 master cylinder with the proportioning valve.  So all I need now is the brake booster...but which one? 
 
There is the w51, the w53, and w57 that all came off the 93+ models.  Anyone shed some light on this?  Are they model specfic - 93+ turbo and 93+ non turbo?  And are they specific to ABS?  I do NOT want ABS.
 
Any information would be appreciated.
 
 

Reddtarga - thanks for that, I have edited OP.
 
Ok - so found out a few more things about boosters. 
The W51 is specific to the non-ABS, the W53 specific to ABS and they are both post 92 up to late 93. 
So, going by this, I'd say the W57 come in after 11/93, however is specific to ABS.
 
Whether or not they were fitted to turbo or non turbo cars...well thats a different story.  I got no idea.
 
 

That's a lot of different boosters, but I believe the best one to look for would be the post 11/93 one.
I have found the  later boosters have a lot more power than the earlier ones, even though they look very similar apart from the vacuum check valve location.
 
I know many people with ABS cars simply make up new pipes to bypass the ABS, and keep their ABS booster and M/C.
