People have had interstate cars changed to act through normal inspectors and dickson...
I got one of my cars from nsw to act through a normal inspector.
As for fmic, the rule is if the car came with a fmic oem ie skylines and silvias etc they have a front facing intercooler outside the engine bay then you are allowed one as long as your intercooler piping and core has not required your reo or chasis cut to fit it, for skylines you can put your cold pipe through the floor pan as long as its not going to effect the structure of the plate under the washer bottle, or through the side just above the chasis rail providing there is still metal attached to the rail (a inch is enough above it)
Hope it helps
