Would stronger Zero engines change the early carrier battles?

Would more powerful Zero engines have changed the early Pacific carrier battles?

Probably not, although they would have made the Zero faster, more maneuverable and more lethal.

Earlier access to stronger engines could have improved the Zero's speed and power-to-weight ratio at Pearl Harbor, Coral Sea and Midway. In this counterfactual, its maneuverability and lethality would increase as well. The judgment is that the stronger aircraft probably would not change the battle outcomes. Its wider effect on Japanese capabilities and the war remains unresolved.
