Hi i have a ford escort lx 1995, i currently have a fiesta 1.6 dohc engine situated in it running the fiesta 1.6 gearbox with the starter at the front of the engine.

I also have a 1.8 fiesta dohc engine, completely identical to the 1.6 dohc engine, what i would like to know is, is that someone told me that i can put this engine straight in and run the same 1.6 fiesta gearbox and the current ecu, i know the gearbox will fit ok but will the engine run ok with the 1.6 ecu and wiring loom? if not how can i work my way around it and what do i need to do to achieve this??? also would there be any side affects by doing this???

the original engine that was in this car was a 1.6 16v zetec engine, had to change the gearbox obviously because starter was in a different place.

Any help and advise will be truly grateful as i dont want to put the engine in if its not going to work ok
