Nitrous works very well on these engines...will make extra power for sure.... just difficult to get the mixture right, have to use some of the nitrous pressure to pressurize the fuel tank via a distribution box... you can make quite a bit of power with it as it allows you to burn more methanol which carries more overall energy density then Nitromethane....
Turbo's work on 2 strokes..... even ones without exhaust valves ( exhaust valves just slightly alter exhaust timing or flow path volume ...from 155-190 degree..but the exhaust is still wide open
Superchargers also work on 2 strokes as well.........just issue is we have no proper superchargers for our micro engines and no proper turbochargers...
but regardless you can boost 2 strokes both by supercharger and turbocharger as well Nitrous does work and works really well at making power, issue is good luck keeping your glowplugs intact.....
