Having done this a couple of times, here is what I used.
Stanza struts (cut down with coilovers).
1200 or stanza lower control arms (ones I got were the same).
1200 steering arm, outer and inner tie rods.
1200 radius rod
1200 ball joint (there are two different lengths)
1200 strut tops.

Stanza struts are too long for 1200s.

Stanza shock length is 438mm.
200b is 403mm,
standard 1200 is 418mm,
R31 is 363mm,
z31 is 357mm.

So it depends on how low you want to go.
There are a few problems with lowered stanza struts and decent size wheels.
You can't get away from the scrub with this combo, wheel and tyre combo are limited due in offset, due to the space between tyre and spring (for lowered). But with rear wheel drived cars it is acceptable.

Moving the inner mounting point of the LCA out by 10mm will provide more static camber, this should be able to be accommodated by the tie rods, same effect as using the longer ball joints such as that in the utes (and i think 120ys as well).

Moving the inner mounting point of the LCA out and up is a way to address both the roll centre height and static camber or you can use adjustable camber tops, longer ball joints, and spacers between the strut and steering arm to achieve the same outcome.

Depending if it is full race or race/road combo. Full race I would recommend looking at R31 struts in lieu of Stanza, the strut offset allows for great wheel choice and less scrub, the compromise here is the R31 struts are about 1 deg less static camber to that of the Stanza setup, this will have to be compensated by some other means.

Generally, when you are working with a combined brake master cylinder you will need to balance the bore size based on the rear effect (i.e the rears will lock up first) or limit the rears through a restricting valve. This means a larger bore which gives less overall pressure for the same pedal effort.
With a booster, you will loose pedal feel, which you don't want to do for race. However for road, you will require less pedal effort (which is really a comfort thing given the size brakes you are talking about).

But if the budget is tight that selecting one off a doner car is important (not a new one) then Stanza is probably ok i suspect it will be around 7/8 Inch. Really anywhere from 3/4 (will probably require a restrictor in rears or they will lock up) to 1 inch would be fine (will require a lot of force to get the brakes to lock up).
