Into a mk3 Fezzie.

I have recently fitted the silver top 2.0 16v head and block into my fezzie using the 1800 16v clutch, flywheel, oil pump, water pump, oil pick-up, sump, inlet & exhaust manifolds.

Now my questions are, will the original 2.0 inlet manifold have bigger injectors than the 1800 inlet manifold?

Will the 2.0 throttle body fit the 1800 inlet manifold?

And i'm still using the 1800 ECU, will using the 2.0 ECU make any differences?

Thanks.

The 2.0L throttle body will fit but needs some modification!

If you want to run a 2.0L ECU, you need to use an Si engine loom as they have internal edis the same as the 2.0L ECU where as the XR2i one has external edis!

Thanks

Dan,

Cheers mate, so no real benefit to using the 2.0 ECU then and more hassle.

Do you know where i can find what mods need to be done to the TB to make it fit?

[DanS2i]

Have a look on here on how to modify the TB, I haven't done it myself but I know people on here have done it!

The only thing I would worry about is whether the engine will fuel right on the XR2i ECU and whether you would get the full potential from the engine. If I was you I would track down an Si loom and then get the right 2.0L ECU, not all 2.0L ECU's will work!

Thanks

I have a 2.0 ECU which i won on Ebay, its from a manual car. How will i find out if its the right one or not??

As for the loom, i take it i just need the engine bay 1.6si loom? Tell me why i need it again? Sorry lol

Do you think the 2.0 injectors would be better using on the fezzie inlet?

[jdfiesta]

you ideally need an Si 16v loom as stated above. they can be run on the 2i loom though, just not right.
the throttle body is fairly straight forward, take the linkages off the spigot on the 2ltr throttle body, and remove the ones off the 1.6, drill the hole out for the spigot on the 1.6 linkages. fit the linkage onto the 2ltr throttle body, file the lug away on the top part of the t/b, this will let you get full throttle. you'll need to make some kind of arrangement for the acc cable holder, i had to cut the top mounting hole for the bracket, then nip it secure with a screw

injectors are bigger in the 2ltr, but you just need to put the 2ltr injectors into the 1.8 sandwich plate
JJ

[DanS2i]

I would have thought the injectors will be basically the same!

When you look at the ECU, there will be a 4 letter code on it, 2 ECU's that I know fit are DEEP and DESK

For example -


With regards to why you need an Si loom is because the edis on Mondeo management is built into the ECU where as on the XR2i it is built into the loom, which means you can't run a Mondeo ECU on an XR2i loom, so you need to get an Si loom (as the Si has internal edis, the same as the Mondeo) and then use one of the above Mondeo ECU's

Thanks

Si loom is Internal EDIS/External PATS

You can run a 2.0 fine on xr2i management if you want to with a few loom changes. I'm sure Asad will be able to confirm that!

You can indeed use your XR2i loom, to run internal E-DIS, it requires a small amount of work. Third from bottom post or something like that!http://www.fiestaturbo.com/phpBB/viewtopic.php?t=93753&postdays=0&postorder=asc&start=35

Ok chaps, i finally managed to sorce a DEEP ECU to fit to my fezzie - but i'm as confused as hell...........

The current one in the car is...

Fiesta 1.8 litre 16 Valve 92-93 92FB12A650CE XEF2FBCE 105BHP *NEON*

And the one i want to fit is a...

Mondeo 2 litre 16 Valve 93 on 93BB12A650EF XEF3BBEF *DEEP*

Bought here----> http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... B:AAQ:UK:1

Now i plugged it in today and..................Nowt! It turned over but wouldn't fire.

Would someone be able to confirm if i 100% need to do the modifications to the ECU & loom that Scort says i need to do??

I was under the impression that because i'd sourced the DEEP ECU it was a plug'n'play situation?

Early Zetecs came fitted with external E-DIS. I have recently fitted a 2.0 to my orion, and wanted to make use of a decent 2.0 Mondeo ECU. All Manual Mondeo's are fitted with internal E-DIS.

For this setup I used a DESK ECU, I also tried a DEWY, while I was at it. They both worked fine. It's worth noting that you will need to change the MAF to a 2.0 one also. The 1.8 one is calibrated wrong.



I will start with a bit of an ECU pinout chart, as I usually do!! There are a few pins I have not included, for instance Air-Con etc.

It's obvious from even briefly looking at the pinouts, the main problems! Injectors 1&2 are in completely different places. Also the CPS is connected directly to the ECU, rather than the E-DIS unit.

Firstly, disconnect your battery, and remove the ecu. Then try and remove the wrapping tape on the part of the loom that enters the engine bay, to the E-DIS unit.



You will need to run a new wire to the ECU from the CPS. I used a piece of 0.25mm 2-Pair screened cable. This basically needs to be run from the CPS right up to the ECU plug, and connected to - Pins 55 & 56. I had some pins from another old loom, with about 50mm of cable still left on them, as I don't have any ECU plug pins, I soldered the wires to these and inserted thepins. One of the pins is already taken up. Remove this pin and leave it out for a minute.



Once this is connected you can swap some wires over for your injectors.

The coil pack centre wire is an ignition live, and the ECU pulses each coil. I used the old wires that were connected to the injectors, cut and connected them to the DIS pack. These connect to pins 58 & 59,(to which they are already connected) they are fire cylinders 1 & 4, and 3 & 2 respectively.

The next cable and pin changes to be done are for the injectors. You will have cut the cables to use them for the coil pack. I used the two of the cables from the E-DIS unit (to which there are four), and connected them to the injectors. These then need moving from their current positions on the ECU plug, to pins 51 & 51, injectors 1 & 2 respectively.

One of the last connections to be made is for the Tacho. You will have had a green wire running from the E-DIS module. It will be the only green wire there, this needs connecting to the blue and yellow wire which comes from the E-DIS unit and goes to pin 4 on the ECU plug. Bell it out to ensure the colours are the same though!

Pin 16 on the ECU needs to be connected to current return ( the chassis ). I used a short piece of wire connected to the ecu, and connected it near the ECU. This is for the internal DIS.

You will end up with one spare cable going to the ecu, to which I put come heat shrink on both ends and taped back out of the way. You will also have an ignition live feed that went to the E-DIS unit. This also needs to be heat shrunk and taped back out of the way.

Once you have finished, wrap it ull up nicely with loom tape, and your done!



I have been running a 2.0 on 105 1.8 management for a little while now (mainly because I'm lazy!) but I only noticed a slight increase in power. It did however make the engine run much smoother.

Hope this helps someone,

Steve

I am a complete novice and all this ECU business is very confusing!!

Thanks!!!

what i would do is run a xr3i 130 spec 1.8 ecu and loom.
that way its not far out on the fueling side of things.
keep the 1.8 injectors so it all runs sweet.
the 130 spec throttle body is the same size as the 2.0l anyway.

yes but this way the load the engine is out under could not be registered correctly with the ecu and fueled accordingly.

I'd like to see the emissions results of a 2ltr engine running on 1.8 management

It pinks and misfires bad enough on the 1.8 management belive me!

Finally sorting the loom mods tomorrow

[escortbreakers.co.uk]

my old car was a 2.0l running on full 130 spec setup and it was ok.
it done 145mph so it wasnt too bad!!
the k and n didnt really help though because it made it a bit too weak.
a superchip would probably have made it spot on.

i dont think pinking and missfireing has got anything to do with it mate.
i have had many zetecs.
a 130 spec running 1.6 fiesta mangement, ran fine.
i later changed the 130 spec to cvh 1.6 mangement and then to rs2000 mangement and none make an engine misfire or pink.
even my current 2.0l zetec bonus is running 1.6 efi cvh management although it will be remapped before its completely finnished.
