im wanting to get a fiesta either mk4/mk5... and im wanting to carry out 2.0 zetec conversion...

just want to know what ecu fiesta mk4/5 run on. are they eec-iv or eec-v...

if they are eec-v can i just unplug their ecu and insert a 2.0 zetec eec-v ecu and it will work once all connection are conncected or is it not that simple... do i still have to get zetec engine loom and swap it for fiesta engine loom and wire it up with fiesta interior loom.


whats better to start with the 1.3 endura like they do for ka zetec conversion orrrr a 1.25 zetec??

 

there must be someone of this forum who can tell me because tons have peopel have done zetec conversions in 1.3 ka's... and a couple have done mk4/5 fiesta??

 

the looms are different you will have to splice the looms together to make it work as the plugs are different
