Hi all,

 

Im new here on EVO and im driving a mk6 estate 1.6.

 

I want to swap the engine for a RS1800 from a fiesta mk3. Are there any electrical issues that i need to know ? And can i fit the gearbox of my standaard 1600 because the box on the RS1800 is busted ?

 

I've looked up some things on the net but a lot of people say it's just plug and pray. 

 

 

Any help would be nice and will post some pic's when i start swappin.

 

Thnx

Has your Escort got the cast manifold or the later plastic one.  The air temp sensor and maybe the TPS (can't quite remember) are different on the plastic manifold but you can splice the ones in from the RS loom.  Not sure if the RS has external pats or not.  If not it should be just a case of swapping the ECU and transponder.  It's possible to get away with not changing the ignition barrel if you have the Fiestas red key.  Just get a copy of your Escort key done at Timpson and you can simply hold the red key by the transponder during the programming process.

 

The Escort box should fit straight on since it's an ib5 and the fiesta either uses the same box or a BC type.

The escort has an plastic manifold, but the 1800 has still his orginal manifold on it and all its sensors. 

 

If i got it right the orginal wire loom should fit without any prob to the 1800 engine ?

 

Can u give me some  more info about the transponder and ignination barrel i dont think i still have those of the 1800 egine and would it be a prob if you dont have the red key of both engines.

 

and i live in holland so i have to contact a ford dealer for the red key i think.

The transponder is a little plastic collar that fits round the ignition barrel.  You need the corresponding key, barrel and transponder and ECU from the same car.

 

The red key is only necessary for programming new keys, I just mentioned it because it's a way around having separate keys for unlocking and starting the car.  Getting new keys from Ford is expensive and best avoided.  The red key allows you to program cheap replicas you can get cut on the high street.

 

If you don't have the above mentioned items you could try getting them from from another RS1800 or 130 spec XR3i.

I gave recently done this conversion.

 

The original wiring loom will plug straight into the 1800 without any issues.

 

All of the sensors are exactly the same on all zetec engines regardless of inlet etc. Theyre just in slightly different places.

 

Yes the gearbox and flywheel from your current engine are a direct fit for the new engine. Just be wary that your gearbox will probs be rear mounted starter motor and the engine block may be built for front starter (although the block can be ground extremely easily to get a rear starter to fit, i had to do this to mine)

Regarding the ecu and transpinders. Its not just as easy as swapping the ecu and the transponder. The pin outs on the ecu are different fir zetec engined fiestas/escorts/mondeos so some wiring will need to be changed. This is the part i struggled with

 

Firstly find out if your current ecu is 'pre pats' 'internal pats' or 'external pats'

 

Then find out if it is internal or external 'edis'

 

Also find the same for your replacement ecu (to match your new engine)

 

The easiest 130 spec ecu to use is a 'cult' ecu as its internal edis and prepats

That's odd.  There isn't a transponder on yours.  It should be in the second photo.  It should look like this. http://s10.postimg.org/idp3g0wax/Transponder.jpg

Whats odd about it? some base spec early mk6 had no pats

You don't necessarily have to change the ignition barrel just drill a small hole in the chip cover of the new key and use a small self tapping screw to screw into the hole you drilled then use pliers/grips and pull of the cover and remove the chip do the same in old key but replace new chip with old one it's the chip not the key that the ecu needs to recognise
