im in the process of putting a 2.0 litre zetec into my car, im ok with the general mechanics side of things, i just need some help with the wiring side of things, can anybody help?

 

Hi i have done a few, as long as its an efi car you are putting it in its not too bad otherwise its a pain in the arse but i have done it, feel free to email me any worries or ??s and ill gladly help.

 

even if its efi you will still have to fit the complete zetec engine loom or make one up

i thought this would be an easy conversion as i had the efi already ended up maiking a new loom from scratch to get it running

its not as simple as it looks
also you are using the 1.8 sump and pick arnt u

you will need a xr3i or frst flywheel aswell

 

Aslong as the car is efi to start with u will be ok?
What car are u putting the zetec in?

 

it wont though

my car was efi when i done mine

it wouldnt run or it would but overfuelling badly and cutting out due to the zetec uses lamda control for fuelling as the xr use a mixture screw

you will need to fit or make a loom go onto xroc theres someone on there who helped me out a lot

 

so what needs changing then from the old loom to make it run then?
cheers mark.

 

basically the complete engine loom off the zetec you got the engine out

you will need to make a little fuse box and have n igntion relay in there then u just link the fuel pump wires to ur fuel relay

like i said go onto xroc website look for someone called sex3i or something he can help

 

All u have to do mate is order a conversion plate form ian howel at area six or jano at odd kid. This will allow u to fit the mk4 escort xr3i EFI inlet manifold to the zetec inlet port. There for u can just plug all the multiplugs back into the corisponding sensors the enginge will fire streight up.
Me and my mate have successfully done two of these conversions now and are just about to start a third. Another reason for the mk4 efi inlet manifold over the zetecs is that u can remove the injectors and replace them with different types. we have found that focus 2Ltr ones seem to work the best. Also forget about the lamba sensor because Mk4 efi does not use one so if your using part of the zetec exhaust system, just plug the hole up with a bolt or weld.

 

If u need any help mate just let us know ill sort u out with some photos of the conversions we have done. Believe me its a worth while conversion when u have it finished!

 

i agree with above

i was told that i could use my existing management on my 3i and i had efi

the only problem i found doing this is if i use the zetec ecu it would fire up but overfuel badly as the zetec requires a lamda signal

use the original ecu and the car doesnt tickver and runs like a dog due to injectors i think it was

but that above is the easiest to use which i forgot about lol

 

The Zetec - EFi conversion plate makes it very easy and a worthwhile conversion.

 

so it this plate just for the 2.0 engine or can one be used on the 1.8 engine too?, Robliddle might be handy if you could post a couple of pics , and maybe one of the plate too..........Jano_OddKidd how much are they mate?
cheers mark.

 

The plates are made to fit on any type of engine from CVH to Zetec.

For info please click sig.

 

This was the first converion.
Here u can see the conversion plate with the beige focus injectors.

 

U will need to rotate the head!

 

This is the next victim for the two legger treatment!

 

so insted of using the inlet manifold from the engine say a 130bhp 1.8 zetec that you will have to make a loom up for , you can use one of these plates and use you existing efi inlet off the cvh, that will just plug and play, is that right?? and you say you will need to rotate the head???
im all new to this mate, first ever resto and conversion ive done, more info needed lol, cheers mark.

 

If you use the coversion plate all you will need to do is bolt on the Manifold.

No rotating heads or anything.

Just plug and play.

If you are using FRST management it makes it even easier.

Regards

 

No i ment u will have to rotate your head cos picture is on the piss HE HE!
As jano sez bolt on and go. ill send more pics!

 

 

ahh get ya now , was gonna say rotate the head wtf! lol ill deffo be ordering one of them then, Robliddle more pics would be really handy mate
cheers mark.

 

Here is a pic that may giv u more of an idea mate.

 

can u not change the injectors in the 1800 zetec efi inlet manifold then,im going 2 be putting an 1800 zetec into my escort estate turbo then turbo it aswell so will i need a different inlet manifold atall,sorry 2 go a bit off topic

 

The injectors are a different type which do not fit in the std place maytee

 

This is why every one favours the cvh Efi inlet manifold over the zetec, and go to the trouble of using the conversion plate.

 

OH NO!!!

What kind of injection do you want to use on your 2.0? 1.8 130 hp or 2.0 Mondeo...

A friend of mine put a 1.8 with whole injection in his 1990 MK4 EFI. Was a straight job. Just took all the plugs off the old engine. There are only 8 cables that must be connected to the Escort, the rest of the loom can stay standard!

The same did this guy with the 1.8:

Agreed, if your going for NA zetec, don't use the 1.6cvh management.

The fuelling and ignition tables are wrong for a start. You would also lose out on closed loop and sequential fuel injection, all provided as standard by the zetec ECU.

It's really not that much of a pain in the ass to convert these cars. It just takes a few minutes of consideration.

There are also injectors that will fit into the zetec manifolds too. Some japanese cars are fitted with injectors that are a direct fit. They are also available in larger sizes (also saturated) for use with EEC-IV.

but it seems to me that using one of these plates is a hell of a lot easier than having to make up another half loom to run the engine on,

lets face it thats why the likes of jano made them in the first place

ill deffo be buying one as its gonna make it well easy for me

cheers mark.

 

I'm pretty sure Jano makes the plates for people doing Turbo conversions mainly. It saves all sorts of problems.

If your doing a NA conversion, to a 1.8 or 2.0 engine, why would you use 1.6 EEC-IV? The fuelling and ignition tables, as I say will be wrong. It just seems a bit wierd to buy something extra, and have it running wrong. When all the parts from the 16v engines are available two 'a' penny.

It's only advice moondust, but why didn't ford just make up a plate like that for the whole escort/mondeo range?

Steve

 

The best way IMO is by using the CVH EFi manifold as it costs very little and is available off many engines like FRST, XR2i, Orion/Escort EFi. The cost of the manifold with all parts like throttle body injectors fuel reg fuel rail etc.. should cost no more than Ł20 bolt it on to a Zetec head with the plate. Thats it!


The plates on offer are made to work with many types of systems like:-

Zetec with carbs. Twin choke, Throttle bodys etc..

Zetec with CVH EFi

Zetec Turbo with CVH EFi

Zetec Turbo with Rover EFi

Zetec Turbo with Motorbike carbs

+ any others you need made please ask...

They just make them to make money. They don't care if a 1.8 130 PS Zetec runs like a bag of nuts!

IT REALLY IS EASY! Just take all the connectors off the CVH, put the whole Zetec in, connect the ECU to ignition and some other things. Modify the loom is the work of half a day.

But do it as you like!

 

im thinking of doing this conversion , using the plate idea sounds good and easy but does it make much diference using the 1.6 ecu ???????

 

yeah course they make them to make money, but also they found a gap in the market and are supplying people with what they want.

personnaly i WILL be using one of these plates, because im looking for the easy option, i dont wanna spend half a day modifying a loom to run the engine off, plug and play thats what i like,

each to their own.

cheers mark.

 

Just use the zetec inlet and loom. far less hassle. even if you manage to get it running with the efi cvh ecu then it'll run like a dog like rich's did, won't make sense of the TPS and will have fuelling all over the place.

We spliced the zetec loom in same as on mine and it fired up and ran sweet as a nut. on efi or mfi it's the same wiring you just need to use a yellow fuel pump relay instead of the pink one on mfi. 3 fuses and a bit of patience and you're away.

 

would you wire 1 up for me if i paid you as im crap at wiring things ......

 

of course when?

 

So which part of the loom did u exactly use. I know when i converted mine, the zetec engine i bought from the scrappers had all the wiring on it and it all went to a multi plug which i would have thought plugged into the cars main loom. Where did u go from there? Must say i used the XR3I EFI manifold with converting plate and it runs fine.Only mod i made was changing the injectors for Focus 2Ltr beige ones. I can understand what your saying about using the more modern managment Quite fancy giving it a go just to see if there is any difference?

 

I used the entire zetec engine loom, spliced a few wires from that big multiplug into a mini fuseboard for lambda fuse, ecu fuse etc that are obviously not in existing fusebox. Then run it though a yellow fuel pump relay and ignition relay, hooked it up to perm live, ign live and fired it up

only other thing you have to do is hook up an earth to the temp guage multiplug. some people use a cvh sensor and the old wire but I don't see the point when it's just a case of splicing in one wire as opposed to swapping sensors. Then if you have mfi, you need an efi rev counter, hook it up to the coil pack or edis module and watch it hit 7k

Then when I'd got mine running, a few weeks later I met rich (xr4x4rs) and we did his loom the same as mine as he was having trouble trying to use his efi loom.

 

see when i did my conversion i couldnt find anyone who did adaptor plates

i was advised that it was just fit the engine and swap ecu over job done which was the complete opposite

i couldnt know matter what get it to run on cvh management i had to use the zetec wiring wirimg loom

so sexr3i came to my rescure and gave me hand we finally got it up and running with not a single problem and fuelling was spot on to using lamda control

i did later make my own loom and start from scratch using a haynes manual basically started from multiplug and done each wire at a time as originally i used the zetec loom off the fez so was a bit short in soom places

but once that was done it made the car look a lot neater under there

and the car is still going strong as the new owner is a friend and he hasnt had a problem for the past 6 months

 

i had my mk4 2.0l zetec running on mk4 efi management.
i also had it running with a rs2000mk5 ecu on the efi loom.
but it never ran 100%
fueling is out, its ok if you are getting it mapped tho.
but why bother, fit zetec loom and ecu or get magasquirt or simular and get it mapped properly.
