Similarly, OP mentioned "modular single cylinder engines" or basically what those fuckin russians do for a laugh on the internet. These jerkoffs made a V16 out of single cylinder chainsaw engines. Thats basically the modularity OP was talking about, but in reality its just not efficient for any metric. Too big, too heavy, too many losses, overly complicated, etc. What I said about the V2 cylinder section still applies: you end up introducing too many seals for oil, water, and pressure to fuck it all up.
