all 2L N14 brakes are same, this goes for some pulsar Q's, Ti's, and the SSS range. (anything with 2L in N14).
they're not as big as the AD22VF's which come in the N15 2L, and GtiR pulsar.
the AD22VF's that come on the N15 and GtiR will fit inside the regular N14 alloy wheels (SSS wheels).
I have the SSS alloys on my micra, so could run the AD22VF's.
As mentioned in the past on this site if you dont want the much larger and heavier rotor of the AD22VF. the regular N14 2L or even 1.6ltr brakes would be a worthy upgrade.
I plan to put the N14 2L brakes on my micra sometime soon as I have two spare sets laying around.
Any brakes that fit on an N14, 15, gti-r pulsar will fit on a micra. washers may or may not be required, best thing you can do is pop the rotor on, bolt the calipers on without PADS in it, and take note of how much gap there is in the caliper on ea side of the rotor, space out as required, it's perfectly safe.
DBA make slotted rotors for pretty much all pulsar brakes.
