used motor with about 50k on it, under 1000$.
Also the difference in displacement is made up by the stroke of the motor and not the bore. bore is same size on both 4 cylinder duratecs, the 2.3l has the butterflies on it like on a qr25de nissan motor or i think like an SPI motor has, opens up for more air flow at WOT and certain RPMs i think.
