No, Momo hubs will NOT fit nismo steering wheels.
Nismo steering wheel mounts like a Nardi, which is also 6 bolt, but arranged differently from MOMO/Sparco (which ARE the same).
OTOH, a momo hub will fit a TRD wheel if you have one.
AFAI understand, all nissan steering column splines are the same, meaning you could *conceivably* use an S13 hub on an S14... however, the S14 has a few complications re: airbag and mounting surface (somewhat different from what I've seen)... so unless you absolutely can NOT get ahold of/afford an S14 hub, try not to use an S13 hub on an S14 chassis.
