I don't understand it If it is an engine swap is it worth the effort and money? See Quote below,
"The engines in the 2000 Toyota Echo and the 1999 Toyota Corolla are not directly interchangeable. While both vehicles use inline 4-cylinder engines, the Echo's 1.5L engine and the Corolla's 1.8L engine have different specifications and configurations.
Swapping engines between these two models would require significant modifications to ensure compatibility with the vehicle's electrical systems, fuel lines, cooling systems, and other components2. It's not a straightforward swap and would likely involve considerable effort and expense."
