the easiest to find information I would say is doing the 200sx rear calipers w/ brackets. Go to
http://www.the510realm.com and do a search. check this site out too for the 200sx calipers,

for the front i have seen most people swap out the complete strut assembly, disc brakes, rotors from a 280zx. do you research on the years. there are tons of options. the510realm.com is a great source. i did 280zx disc in the front and rear. there is an article on the dimequarterly site on how to do it. The front is a straight swap for most dic brakes, the rear almost always needs some sort of fabrication unless you keep your drums. Some people may tell you that just upgrading the front will be fine. im not an expert but keep searching, you will find what you need.
