A two stroke would be more historically accurate, assuming Gabe is making something more similar to the first generation design, or even a kei car at all (could be planning on anything from a Willys Jeep to newer SUV based on what he said). Kei cars were only allowed 360cc before 1976 so two stroke was really the only way to get enough power. While I personally would love a two stroke, it may require better exhaust simulation and, as I said before, the Pigeon isn't historically accurate as-is. I don't know, I'm just writing as I think. It's up to Gabe.
