Yes you can get the S14 SE 5 lug rotors for the rear and use your stock brake hardware after getting Nissan S14, Z32, or Q45 5 lug hubs.
For the front you need S13 5 lug conversion hubs or a lot of S14 parts to use the S14 SE rotors or opt for Q45 rotors and Q45 calipers and brackets (but use the S13 bolts on the Q45 brackets) for more stopping power while still using stock brake lines.

Lots of info there on 5 lug conversion and Z brakes, near the bottom is info on the Q45 gear.
