The TEXTRON LYCOMING FAA Certified 320 Series four-cylinder engines power numerous light aircraft manufactured by companies like Textron Cessna, Piper, and kit manufacturers such as Van’s and Glasair. They also power the early Robinson R22 helicopter.
This engine family externally resembles the TEXTRON LYCOMING 235 and 290 engines from which the 320 Series engines were derived. The TEXTRON LYCOMING 320 engine range includes different variants, indicated by prefixes, such as O-320, the fuel-injected IO-320, the "left-handed" version LIO-320 with the crankshaft rotating in the opposite direction for use on twin-engined aircraft, the inverted mount, fuel-injected AIO-320 as well as the aerobatic, fuel-injected AEIO-320. Please refer to the Product Description section for an overview of 320 engine variants.
The specifications of TEXTRON LYCOMING engines are set in their PNs and ENPL number because every engine is provided with slightly different specifications depending on the aircraft application.
The TEXTRON LYCOMING 320 Series engines can be supplied as OUTRIGHT SALE which does not require a trade in engine or core excharge or with core return. Engine prices differentiate on the basis of the selected sale option, condition as well as engine configuration and require confirmation at the time of ordering. Please contact us, indicating the engine ENPL (whenever possible) for additional information and a quotation.

The TEXTRON LYCOMING™ non-certified engine solutions for experimental aircraft include their standard experimental engine models and their premium Thunderbolt product lines, the company’s brand of high performance, built-to-order powerplants for these aircraft.Both are non-TSO versions of genuine Lycoming engine modesl, factory built and tested. In addition,TEXTRON LYCOMING™ lineup of engine kits is also available assembled from 100% Lycoming parts and tested before delivery.
Instead of being made on an assembly line, each THUNDERBOLT™ engine is factory hand-built and further customized & personalized through the selection of several popular options of fuel systems, ignition systems, performance enhancements and finishing options. Also, most of THUNDERBOLT™ experimental engines contain performance-enhancing modifications such as high-compression pistons, cold-air induction, and electronic ignition designed to increase horsepower and flight efficiency. All engines feature a balanced rotating system within 0.5 gram (connecting rods, pistons, piston pins), ported and polished cylinders, and customized paint options.
The TEXTRON LYCOMING™ THUNDERBOLT™ engines are offered in Signature, Extreme or Competition series and cover the full spectrum of Lycoming familiar O-235, 320, 360, 390, 540 and 580 cubic inch models, although the IO-390 and IO-580 are the most popular.
Of the engines offered, all use parallel valve cylinders except the 390 and 580, which employ angle-valve cylinder heads. That makes them more efficient and powerful, but also heavier and more expensive.
235 and 320 Series include four-cylinder engines with models producing up to 125 hp at 2,800 rpm and 150 or 160 hp at 2,700 rpm respectively.
360 Series includes four-cylinder engines producing 145 to 210 hp. They are extremely popular due to their rugged reliability with smooth performance. Respective Lycoming’s 390 Series four-cylinder engines produce 210 hp at 2,700 RPM.
540 & 580 Series are powerful and durable six-cylinder engines. Those in 540 Series produce 235 to 360 hp at up to 2,700 rpm with their counterparts in 580 Series producing 315 hp at 2,700 rpm with reliable direct drive and excellent power to weight ratio.

This top quality TEXTRON LYCOMING Baffle Spring Compressor speeds up the removal & installation of cylinder baffle springs. It eliminates the danger of broken or bent cylinder fins caused by use of screwdrivers and punches. This tool is easy to use and features two pivot locations for parallel and angle valve cylinders.
Lycoming cylinder kits come complete with a nitrided steel barrel, a new aluminum alloy cylinder head, piston pins and plugs, intake and exhaust valves, chrome oil and compression rings, valve springs and seats, retaining keys, and all gaskets and seals. The cylinder barrels and heads are engineered for unsurpassed strength and performance. The nitriding process provides the cylinders with a thick armored protection that significantly outlives other hardening processes. Lycoming cylinder design dissipates heat quickly and evenly.
Lycoming cylinders come with a full two-year warranty against defects in material and workmanship – regardless of the number of hours flown.
These bolts are for use in Textron Lycoming aircraft engines. Supplied with our own Certificate of Conformance. If additional certification is required, please contact us as a respective charge may apply.
