shorter with either cylinder bore?
>engine would have the same length with either .5 or .4 liter bore. I’m not sure but I think the 0.4 has thicker walls so the engine can be used with high pressure fuels as methanole. But, even with thicker walls, the engine should be shorter. Don’t forget that these engines uses small ang long cyls. The inline 6-cyl engine is shorter than other 6-cyl engines. The 5-cyl is nearby in same lenght as a normal 4-cyl engine.
