Claiming “the weight and size of a 320 with the power of a 360,” Engine Components International (ECI, Booths 269 & 270) unveiled its new TITAN 340 Stroker Monday morning at AirVenture 2013. “It looks like a Lycoming, it sounds like a Lycoming,” the company added, “but it has a higher power-to-weight ratio.”

The 180-horsepower, four-cylinder piston powerplant received FAA STC approval on May 1, and is intended as a direct replacement for existing 150- to 180-hp Lycoming engines. The new engine will cruise at 2,400 RPM with a constant-speed propeller, the company added, and will bolt up to existing cowling, baffles, exhaust and engine mounts in aircraft previously equipped with Lycoming 320s.

ECI also offers the engine for experimental and special light sport aircraft (S-LSA) applications, with an ASTM-approved variant powering the CubCrafters Carbon Cub SS.

Engine upgrader Texas Skyways of Boerne, Texas, is flight-testing the TITAN 340 Stroker in a Cessna 172, with later plans for STC approval in selected Piper airframes. ECI plans to offer both carbureted and fuel-injected variants, with magnetos or electronic ignition. Recommended TBO for the STC variant is 2,000 hours.
