EA 81
I took a fresh look at the EA 81 to see how close to a Geo it may come out, it worked out to be 5 lbs heavier then G1.3B installation that I am flying, here is some sharing information I have not tested this in an airplane!
dry sump oil pan also engine mount pad 8 places if needed
SPG-2 gear drive, dry sump oil system and fuel injection, fits in 22"h x 28" long
More to come
