Engine Components debuts STC’d O-340

OSHKOSH, Wisc. – San Antonio-based Engine Components (ECi) debuted the third in its Titan 340 Stroker series engine here on Monday. The new STC’d version follows Experimental and ASTM versions of the engine.

“The 340 fits the same weight, size and mounts as a 320,” said ECi general manager Tim Moreland. “It is a direct replacement for the 150, 160 or 180 horsepower Lycoming.”


Owners of A, B, C, D and E series 320s can swap out to a carbureted or injected 340 with no changes to the exhaust or engine mounts.

Texas Skyways is performing the airframe STC work. “We expect the STC process to take about 12 months,” said Jack Johnson, Texas Skyways owner. “We can use the same mount, baffles, accessories, which makes fit and finish easier.”

ECi is promoting a $29,200 price including an engine trade-in and can been seen at AirVenture in booth 269-270.

      Their web site shows recommended 100/100LL. That fits in with so many that “need” more power. It would be so simple to build for lower octane ratings but the advertising wars won’t allow it. If Pratt & Whitney could build 1300+hp 80 oct. engines (R-1830) 70 years ago the reason certainly is not technical.
