Hi All,

Im putting a 2 litre silver top zetec that i removed from a S reg mondeo into my mk2 fiesta XR2 rally car. Everything is going well but the issue i have is the wiring.
Can some one help/advise/instruct me on how to graft the mondeo engine loom and all the necessary parts into the Xr2 srandard loom.

I know that i need to change the fuel pump, put a swirl pot in and fit a new/seperate fuse box to take extra fuses for ECU wiring.

any help will be much appreciated.

Thanks.

 

when my mate did his it was only 5 or 6 wires ill try find out for you

 

he says theres a guide on xr2.com in the commonly asked questions

 

Great, thanks for that. Will have a look shortly. Does your mate have any other tips from when he did his conversion?

 

pm me a list of things u need to know an ill put them to him, all i remember is fiesta rst/escort xr3i efi flywheel, need to drill bolt holes slightly bigger, cant remember size he will know, escort rst clutch, top engine mount mod which is piss, he used a 3.0 v6 espace inline fuel pump, im not sure he even used a swirl pot tbh but as your goin on track u wil need one, apart from the wiring im sure thats about it

 

oh and as far as i know he was using the mk5 xr3i 130 ecu so no P.A.T i think very early mondeos were also non P.A.T if you did wanna use the 2.0 ecu

 

Oh cool, i didnt realise you could fir a XR3i flywheel.

Iv just fould out about a Megajolt management system which im tempted by as id like to map it and be able to set it up well.

Anyone know if this is a good product? It seems very cheap at £195 for a Zetec system.

 

yh thats what he used, as said thr boly holse need drilling out ever so slightly

 

Make sure the flywheel is from an Efi cvh. Iirc you need to drill them out half a mm. But it was almost 15 yrs ago i did mine.
My 2nd one was 1.8 N/a and i even ran it on xr2i management but was a proper budget banger. Lol
