If it had space for a camshaft I'd think of making one of these compressors into a four-stroke motor. I wonder if it would work as a two-stroke? You'd have to cut ports into the cylinders and add a cooling jacket, but it might work. Maybe I'll make a separate thread for this.
If you are not into wild horsepower or speed, make an atmospheric intake and an exhaust port thats pretty simple.
