It will work with the stock mk1 MC but you will get more pedal travel, the best thing to do is install the rev2- mk2 MC which has a 15/16ths bore compared to the mk1's 7/8ths bore.... so you will be moving more fluid to the calipers but at a slightly reduced pressure.Your 4 pot st205 calipers have more piston cubic volume than stock mk1 single pot calipers so the larger MC is recommended.

mk2 n/a - turbo servo's are the same. So doesn't need to be a turbo one.

I see you have a mk1a so you need to change the servo to mk1b mate, mk1b has the same mc mounting as the mk2 the mc will not fit on a mk1a unless yours is a cross over mk1a that happens to have quite a lot of mk1b parts fitted, have a look at your mc is it 2 or 4 bolt fixing.

The mk2 mc should have the bore size stamped on the side or cast get the seller to check it out is the best option.

Gary had a servo going spare but I don't know if rob has dibbs on it.

I think you need one from a 93> Mk2 but I could be wrong.

looks like a mk2 type 4 stud fixing should fit a mk1b servo if you have one.
