The Flying Legends museum is only partially correct. Yes, one model of the Zeke did have WEP, but it's not any of the Zekes that we have in-game. The Zeke that had WEP was the A6M5c Model 53 (some reports list the A6M5c Model 52 as well) when the Sakae 31 was installed. Our Zekes don't have that engine.
