For sale is an Experimental Aircraft Engine. It is a Subaru EA-81 automobile engine converted for experimental aircraft use. It is an 1800cc, horizontally opposed, liquid cooled 4 cylinder engine. This engine came directly from Japan, which means it has a "hot rod" camshaft in it that is not available on US models, and had less than 10,000 miles on it when removed from the vehicle. The engine has been completely inspected for tolerances and serviceability.. The engine in this configuration is reported to put out about 90 horsepower at peak RPM. Some report 100+ but 90 is a pretty safe number.This engine is vey nicely accessorized with custom, chrome molly, powder coated, vibration absorbing engine mounts and powder coated valve covers and oil pan as well. It has a custom, hand rolled and hand built, fully stainless steel exhaust with EGT bungs already welded in place. Engine turns freely and easily (with spark plugs removed, of course). The greatest feature is the 1.85/1 Ross Aero reduction drive that slows down the propeller down to normal operating speeds (usually <3000 RPM) while operating the engine at optimum RPM (5000-5200 RPM). The unit was built especially for this engine by Lou Ross and his son Chris, in Tucson, AZ. I lived there at the time and was able to witness and be involved in the whole process. Lou died some years ago and Ross Aero is no longer in business, but all of the gears, bearings, seals, etc. are from Ford and easily obtainable should one ever need to repair or rebuild the re-drive. Feed and return oil lines are plumbed in with stainless braided conduit. Prop hub is industry standard 6-bolt.
Intake is a custom built, long-runner intake that feeds both cylinder banks evenly from a Weber, constant velocity carburetor (which reduces or eliminates the need for a mixture control at most commonly flown altitudes). Internal cooling crossover was maintained in the production of the intake. Also includes are a starter, an extra Weber carburetor and two light weight radiators (only one is needed for most applications).
As I'm sure you can imagine, I have well over $4000 invested in this engine. It was to power my Dragonfly project which, due to a significant theft and vandalism event a few years ago, I have abandoned. The engine is all I have left.
