I'm going to take the engine out of my 2.0l 16v Mondeo

i want to use (to put on my 1.8 16v XR2i)

-Cams
-Throttle Body
-ECU
-MAF
-Under Piston Oil Jets

Do i need to take any other bits off the car before i scrap it

(I will be keeping the entire engine)

and does it make a difference to the ecu or any other bits if it's an Automatic???

Cheers

[hb69]

why arent you just putting the whole 2.0 in?

[Dwayneology]

want to keep part of the orginality to the car e.g keep the same block in it

i hopefully fingers crossed have just bought a 2.0l 16v s3 block off a mate of mine

i want to turbo charge that

that will go in this car eventually but for the mean time i just want to put the rs1800 touch too it

Cheers

You should really get the RS1800 ecu, and use the original MAF. Because you've got the XR2i you'll be able to get the older and more readilly available ecu. (talk to Smo to confirm the code)

[Dwayneology]

ok will look at doing that

but whats wrong with the mondeo ecu??

Cheers

[Ollybee]

It's an 1800 engine.

[Dwayneology]

i am listening to what you are saying

but in the zetec tuning page on the main site under

105ps 1.8 tuning it says

"certain Mondeo 2.0L parts can be used, including 93-95 ECUs and all 2.0L cams"

or will i get better performance from an rs1800 ecu

Cheers

[Ollybee]

I've heard of people using the 2.0 ecu, you will also need the 2.0 MAF and TPS. I've been told the 105 ps injectors are the same as the 130 ps so you wont need to swop these but I don't know how well they will run on the 2.0 ECU. It will run the engine but I would have thought you'd be better off running the ecu specifically designed for the engine you are trying to build. Various others on here have converted to the 130 spec 1800 myself included. It would be interesting to see out of those who used the 2.0 equipment if there car runs any differently.

[Dwayneology]

Right i took the engine out of my mondeo on the weekend

i took the ecu out as well

i've decided to put the 2.0 in my fiesta

my two questions are.....

do i need anything other than the engine, ecu and edis unit?

i'm putting the 1.8 box on the engine and using the 2.0l clutch and flywheel

will the fiesta 1.8 inlet manifold fit on the 2.0?

cheers

[Smo]

Right, first of all, are you sure the Mondeo had an EDIS module? As far as I was aware, only early autos had external EDIS.

What's the code on the ECU? The only ones that are KNOWN to work on Fiestas are DEEP, DEWY and DESK, however you need an engine loom that runs internal EDIS... Most, if not all XR2i 16vs run external EDIS, and the Mondeo ECU will not work on these engine looms. You'll need an MK3.5 1.6 16v engine loom or late RS1800 engine loom (both of these cars ran internal EDIS - i.e. no EDIS module as it's part of the ECU).

The 2.0 clutch and flywheel won't fit inside the 1.8 gearbox... You need to use your Fiesta 1.8 clutch and flywheel. Also, if the engine is an auto , you'll need to change your crank position sensor housing, as it places the sensor in the wrong place for the 1.8 flywheel. Auto engines also have different gearbox location dowels in the block and need knocking out and replacing with the ones from a manual (if it is an auto engine).

The 1.8 inlet (and sandwich plate) will fit the 2.0. You'll probably find it makes for a very nice torquey engine, but will most likely restrict it a little at the top end. Still worth chucking on for now though, and may be upgrading to an RS1800/130PS inlet at a later date.

You'll need a Mondeo MAF sensor - did you get this from the car? Any 93 to 98 Mondeo 1.6 to 2.0 MAF sensor should be fine for the job, but it needs to have the code 93BB-12B579-BA on it, so check first - I don't want you shouting at me because you've taken one from a 1.6 Mondeo and the code was totally wrong

[Dwayneology]

cheers mate that was very helpful

it is an auto engine and the edis was external i took the whole until including
the back plate it was connected to,

does that mean i don't need the loom

it is a 1993 2.0 16v out of an l reg mondeo

i haven't scraped the car yet i've taken everything out of the car that is to do with the engine
apart from the loom do i need that???

Cheers

[Smo]

I would be very surprised if the loom was of much use... To be honest, the best loom to use would be one of the ones I mentioned above that use internal EDIS for use with one of the ECUs I mentioned above. It would be well worth getting the correct bits from the start

[Dwayneology]

so i can't use this ecu, even tho the edis unti is in exactly the same place as it is on the xr2i 16v and the loom in the fiesta isn't any good either is it??

thanks

[Smo]

What you need to remember is, we're not Mondeo experts on here, well at least I'm not.

The fact it's an auto setup will probably add complications... I could be wrong, but I should imagine there's various ECU functions that are transmission-related which probably mean making it work within a manual Fiesta setup a bit tricky! You never know, may be the ECU would work, but I would be surprised and I wouldn't recommend trying it myself without knowing far more about the ECU and what it controls.

[Big Walker]

I thought that it was arse about face,

With the EDIS setups it Si was External and earlier was internal

[Smo]

Nope, other way

[Dwayneology]

i'm an apprentice mechanic and what i've learnt about ecu is that it is all
engine control on early ecu's like on this i'm pretty sure that it doesn't control
the transmission,

I know on Later ecu's on stuff like audi's and reno's the ecu controls the transmission
as well as most things on renualt (Buckets of crap)

but i am going to take your advise

so i need a wiring loom out of an si and
an ecu off a 93-95 manual mondeo is what your saying ??

do i also need the internal ecu??

cheers

[Dwayneology]

The Code i have got on the ECU is EARS does that mean i cannot used it if not what code ecu do i need to get the edis i have got is an external on the 2.0l

cheers

[Oranoco]

iirc you need a DEEP, DEWY or DESK ecu

Don't go expecting anyt big hikes fitting these bits. Standard 130PS motors never make the claimed figure and typically make about the 120 markconverted cars are usually down a little bit more again. I can report that we've had good results with Pipers reprofiled cams on the 1.8 Zetec.

[Dwayneology]

alright now i'm confused

So to fit a 2.0l in my xr2i 16v some ppl say i'm going to have to change the loom

yet others say i will not have to chnage the loom

i know i've got the wrong ecu

the edis on the 2.0l i've got is external

do i need to get an internal edis or can i just "Plug and play" the xr2i 16v wiring loom that is already setup for the
external edis

or would it be easier for me to go back to my orginal idea and put the 2.0l stuff on the 1.8l


don't know what to do

cheers

[Oranoco]

Drop the whole 2l in as ironically it will be cheaper to insure than the normal 1.8 with go faster bits. And the 2 litre motor will actually give you the 130PS.

Have to admit I tend to bail on wiring issues and get a mate to do them. I'll ask how he went about it

[Ollybee]

You shouldn't be confused! It's written down here and gone over again in the same post. There is also a fully detailed guide in the guides section.

[Dwayneology]

i can't find it in the guides section again sorry i'm a retard could you post the link again plz mate

cheers
