Continental 4 Cylinder Engines


We have done a number of smaller Conti engines, the first back in 1996. Mark Snow was an early SDS user on his C-85 powered Dragonfly, accumulating over 750 hours. Justin Mace had 350 hours on his SDS equipped, O-200 powered Dragonfly.


Fuel and spark control kit for O-200. Wiring harnesses, fasteners and plug wires not shown. $4411US for single ECU system with no options.

See the article in the June 2018 Kitplanes magazine on our O-200 system


O-200 Installation manual


Bert Caron is doing an SDS EFI installation on an O-200. With some fin mods, he was able to fit the Lycoming style injector bosses into the Continental heads.


Mar. 15/17. We acquired an O-200 for jigging and development purposes. This was used to design and some new CNC'd parts to make the installation easier on these engines which resulted in our new EFI kit shown above.
