Not really, it was one of the only turbo-supercharged planes in WW2, using exhaust gases as power for supercharging, making it easier to maintain boost pressure at high altitudes.
The water/methanol injection acted as cooling, not as extra oxygen, but the cooling in turn allowed higher boost pressures and higher air density being pushed into the engine, so yes, it has some characteristics of nitrous.
This was however not unique, both German and Japanese planes used this ik the war.
It was unique because of combining turbo-supercharging, radial-aircooled engine, water/methanol in a single engine fighter with a study frame.
