It can be done but a few things must be accomplished.
1. You will have to have 4mm machined off the diameter of an U13 altima rotor and the rotor is only 22mm thick. The 300zx brakes you should use would be the NA 1990, they are 26mm. The rotor is only 22mm, so that means don't wear the brakes all the way down. If you can find the aluminum caliper, it would weigh less than the iron.
Another option is using the 300zx rotor for what ever caliper you use, i.e 26mm or 30mm. You would still need the rotor redrilled to to either 4x100 or 4x114. The diameter may still need to be machined down as well, about 4mm. The benefit of this option is using the correct thickness of the rotor paired with the caliper.
2. If you use option 1, the lugs will have to be redrilled to 4x100 or you can change out your hubs for B15 hubs and then you will have 4x114, which is lug pattern of the u13 rotor.
Note: I don't know if machining 4mm off the rotor is necessary if you just redrill the rotor for 4x100 and use the B13 knuckle. If you don't redrill and go with a B15 Knuckle, you will have to machine the rotor diameter down.
3. The master cylinder on the B13 is not up to the task of pushing 4 piston calipera. So a U13 altima non abs master cylinder would have to be sourced as well, 94-97 body style.
4. The brake bias on the this setup is is going to be very strange. I would also recommend upgrading the rear brakes to something bigger as well. Alot of B13 guys go with the 1994 nissan maxima rear caliper and rotor as a normal brake upgrade when they to the nx2000 brakes, this should help with the brake bias.
5. Remember that if you run b15 knucles, the lug patter changes to 4x114. So if you don't change the back to, you will have 4x100 in the rear. So you must keep that in mind when installing wheels. A 15" wheel is a must to clear the 300zx caliper and a min 38 offset should clear.
Seems to be alot of trial and error involved in this setup. If you have access to 300zx calipers, I suggest some testing to make sure everything fits like it needs to and you know exactly what needs to be done. The 300zx lines are not banjo fittings either.
