I've seen 2 1Ms here in WA and I was happy to see them out there and being driven but I wasn't wowed.
N/A means anything that rely's on the engine itself for power with no external power additive like a turbo, s/c or nitrous. Forced Induction (FI) means anything that rely's on an external power to boost the engines capability, so a turbo, supercharger or spray (nitrous).

Technically superchargers use engine power to make more power and turbos recover wasted energy (so in a technical sense they both use engine power)
Forced induction is anything that increases the mixture pressure in the cylinders. EGR has this property somewhat too.
While I'm being a bit cheeky here I will say that spray is not FI. Spray changes the fuel type and the pressure created by combustion, but it doesnt change the pressure of the mixture. Rather, it changes the chemical composition of the mixture. -that answer is serious.
