.SUBCKT nor2 a b out pwr
M3 o a 0 0 n w=4u l=0.5u m=1
M4 o b 0 0 n w=4u l=0.5u m=1
M1 n0 a pwr pwr p w=8u l=0.5u m=1
M2 o b n0 pwr p w=8u l=0.5u m=1
.ENDS nor2

Don't have a _spice on hand, but the subcircuit terminal 'out' is not
used internally.  Changing the M3,4 drain terminals to 'out' instead
of 'o' should do it.
