This is a very urgent question that needs answering quickly.....

I cant remember what pins i need to change to turn a XR3I Mk4 Escort into a Rs Turbo.

I currently have an OFAC Fiesta Turbo Engine is it easy to put in my Escort as i have taken the engine out of the Fiesta and the XR engine is dead so i have no car.......
i kno i need to change the map sensors etc but i cant remember what pins to change at all

Please Help

 

Hi mate,

This guide is for XR2i 8v to FRST management - EFI XR3i's are the same essentially so the guide should apply to you.

It's a pretty simple conversion really - like you say you'll need to take the MAP sensor from the FRST.

EFI n/a to FRST guide

Cheers,

Andy

 

1) Pin no. 8 (brown) needs moving to pin 27, which is empty (CO adjuster signal wire)
2) Pin no. 27 (brown/yellow) needs moving to pin no. 45
3) EDIS Module pin 2 (blue/yellow) may now be disregarded as it is not used by the 0FAC ECU (pin 28 on ECU).


There are no MAP sensor pin changes as the OFAC MAP sensor is the same plug as the 3i MAP Sensor, so just plug and play.

 

Cheers Rab that looks like it i have done one before but cudnt remember for the life of me wat to change.

 

Only with the OFAB though, With the OFAC all you need to do is disconnet the wire between the EDIS and ECU (PIN2 EDIS - PIN 28 ECU) , Belive me, Ive done it

 

check ya fuel economy though mate, but ya right !!! it does work, just not the total correct way

we managed to sort it today, got a engine in out and plumbed in in just over 3 hours ,
