The '''Rotorway RW133''' is a piston engine designed for use in [helicopter](/source/helicopter)s and [homebuilt aircraft](/source/homebuilt_aircraft).

==Design and development==
The '''RW-133''' was developed in 1979 as an all-new piston engine for amateur-built aircraft, including a new crankcase oil system. The helicopter version features a dry sump oil system and a [turbocharger](/source/turbocharger) option increasing power to {{convert|160|hp|kW|0|abbr=on}}.<ref>{{cite journal|journal=Air Progress|date=November 1978|page=12}}</ref> All components of the engine are [cast](/source/Casting_(metalworking)) and manufactured at RotorWay Foundries, except the Mallory Ignition and Dell'Orto carburetor.<ref>{{cite journal|journal=Air Progress|date=August 1989|title=Executive Privellege|author=Peter Lert}}</ref>
