Hmm Why do you think we had 2E in the indus and all over the world 4A or 5A or 7A were used in this shape? In the world why only our corolla comes with 1.3 Engine? Its not econo dear economy comes with perfect power to weight ratio you can not get economy out of corolla by installing 660cc engine in it.
