converting my xr3i mk4 escort into a rs2000,

What a waste of time and effort.

It would have been cheaper to sell the XR3i and buy a proper RS2000.

It's not just the engine that differentiates an XR3i from an RS2000 anyway.

Which electrics are you having problems with, fuel, spark, stereo etc... ?

You'll need the entire loom from the donor RS2000, including the PATS coil for round the ignition coil. Not to mention the original key that's programmed into the ECU's PATS system. Infact, AFAIK were early Ford PATS systems not seperate from the main engine managment? (Tim... ?)

I've found in any engine transplants I've done, seperating the engine loom from the interior loom as much as possible aids diagnosis. Once you know all sensors are connected as they were in the donor vehicle, you can track down faults far easier.

I have a feeling yes, certainly the early mondys and 'scort 5's had a separate PATS box.

Tim..

hi

its splicing the rs200 engin loom into my existing loom that im findin very difficult

thanks scot

Go to your nearest Halfords and buy a good quantity of 3M connectors and a few rolls of insulation tape, and your problems should be over.

Rs200 or Rs2000? Different beasts again.

Why? XR3i are becoming rarer.

I'm really a nice guy. If I had friends, they would tell you.

I doubt very very very much that he's got an RS200 engine for his Mk4 Scrote :-)

hi

thanks scot

What part of the loom are you trying to splice? What functions are you trying to wire? Have you got the entire RS2000 loom?

I've just thought about this.

The XR3i on a Mk 4 shape is the CVH engined lump of s**te.

The RS2000 is the lovely-ish Ford I4 twin-cam, isn't it?

In which case, the whole conversion is going to be a tad more difficult than it first appears.

Well no, not really, both engines run EEC-IV and E-DIS and both engines use exactly the same sensors (tho positioned differently) with the exception the I4 has a CPS and runs sequential injection, whereas the CVH Efi batch fires them all at once.

Tim..

Isn't the I4 significantly bigger? - it's definitely a lot taller, which, ISTR, is the reason why the MkV RS2000 had bonnet bulges.

Also depends on how old the XR3i is - didn't '90-spec' models get a different injection system? - meaning a 90 spec would be an easier conversion.

Where there's a willy wanting to do it, there's a way. I've done a C25XE into a Corsa B (V6) - totally different mounts, totally different wiring, totally different shafts.

Well, technically it was just another cosworth turbo 4pot ford.

Yeah, but if the OP could fit that into a Mk4 Escort in the correct configuration, I think the wiring would be the least of his worries ;-)

i have got the engine fitted i used rs turbo gearbox and shafts all o that was easy it the wiring that i am stuck on

thanks scot

I saw tuned 2.2 from an Astra SRi into a Corsa C - that was quite a nice conversion.
