audi 100 brake servo and master cylinder

does any body know if the audi 100 brake servo and master cylinder will be suitable for the brake upgrade that people do, can any body tell me what the part numbers are for the mk2 gti and the passat upgrade that are mentioned in othr threads
thanks for any advice

I'm guessing there will be a few different variations  on MC size for the Audi 100, what size you got?

I have seen a 25mm MC from the 100 or a coupe turbo used on a rocco with the twin pot calipers, I beleive they used a mk1 servo, but it will be a bit overkill.

thanks graham

i think that its still got standard 20mm mc on but havent checked, i assume that its a 20mm on a 92 cabrio.
i was thinking of putting the 16v mk2 servo and mc on but wondered if the same parts were on anything else audi or vw. i think i read that the mk3 passat had the same on. theres a couple of mk3 golf's in a local scrappers amongst other things, so i could do with the part numbers if poss.
