Well, you should ask the people who work at your local Ford dealer.
yes, because it is a diesel engine and has big pistons and slow revs but if it is very bad you should check your engine mountings

It will fit in the space but the mountings are different. The 157fmi is based on the Honda CG125 and the K157fmi on the Suzuki GS125 and Van Van engine.
from the top just dismantle all the wiring,engine mountings and round bolts then be sure while removing if there any undismanteled parts.
