My father had this done on my ex 505 STX. He was stuck in california
with my car with a failed pump unit. The master cylinder for all
sedan from 86 to 88 is the same be it turbo or not, the equivalent
beck/arnley is 072-8174 (can be found between $90 and list of $150).
The booster unit seems the exact same for 86-88 too, and it makes
sense as the master cylinder is the same. Raybestos has a replacement
unit (RPB650498), with pricing in the same range as I gave for the
master cylinder. I haven't bought a beck/arnley master cylinder,
but the Raybestos works fine on my 86 turbo.
Peugeot parts are not that much more expensive, and if they are
available easily, would probably be the preferred choice. My dad
has Peugeot parts. Basically it's like an STI with no abs setup.
Last, you will need to realign the copper hoses. In all, it's not
that expensive or hard, but Peugeot dealers (like where my dad went
as he's not mechanically inclined in the least bit) will charge
you quite a bit for such a conversion. In retrospect, I should
have taken a plane to california and fix it myself, would have
been cheaper, and I would have had an occasion to do some
windsurfing...

The rear rotors, calipers and pads are the exact same on the 86 turbo
with no abs and the later models (V6 and turbo) with abs. Front rotors
are different as there are sensor marks, and calipers are different but
it doesn't affect anything. The only thing to keep in mind is that you
will need the pads for the ABS calipers and not the more common (and
cheaper) non ABS pads for the front.
Last, Alan mentionned that Gunther did the conversion a few times,
and that he (alan) drove one and felt the brakes as spongy. I can
attest that if properly done, they will be as tight as an 86 turbo.
However, if one of the modulation valve was stuck partially closed,
or leaky, this would create a problem. To correct, either replace
the copper line from the caliper to the master cylinder, or get
a copper line joint to replace the valve.
Hope this helps!
