Can anyone tell me the differences between the escort RS and the fiesta RS engines? are the ECUs the same?will an S2 loom fit to the engine?is there a difference in power?ect
cheers

 

Escort Rs has a different head to suit the Mfi.. whereas the fiesta is run on Efi

to fit an S2 loom to a fiesta engine you have to modify it which is more hassle than its worth.. its easier to get an adaptor plate which allows you to fit EFi onto a escort head so then you can use a fiesta loom

and no theres no difference in power between the 2 engine

Escort used Motorola engine managment, fiesta used EEC-IV-management

escort engine used a t03 turbo whereas a fiesta engine used a t02 turbo

and fiesta engine used a slightly smaller clutch as standard

Afaik.. so don't take my word on it

 

rite i see,basicly the engine is going in my mk3 orion and i already got a S2 loom that is fitted for my car just not for a fiesta,do you know what things i will need to add to the loom?
thanks
