1/2 VW Plans

There are various plans available from different sources for converting a full VW engine to a 1/2 VW engine. This basically means removing the rear 2 cylinders, cutting the crankshaft and cam, and cutting the cylinder heads. Various other modifications are needed to seal up new openings keep the engine leak free. These plans were originally drawn by Scott Land in 1995 and were 7 pages long. The rights were purchased by Simplex Aeroplanes in February 2011 and have been revised with extensive information added. The new plans are 13 pages long with additional large 11″ x 17″ detailed drawings which take you all the way through the conversion process and up to starting and running your creation. Our plans call for using the entire case as this is the easier method and in many ways the preferred method for conversion.
