hi all am new to site so ill tell u the problem from the start.
have aquired RS1600i engine and loom for my project fiesta XR2i but have been told that the loom I got with the engine is for the XR3i.
I am also missing the twin coils and by the looks of it the injection/ignition moduel.
If anyone can help it would be apreciated

Is the wiring loom one big loom all connected? the RS1600i ignition wiring loom is seperate from the main loom, whereas the XR3i is part of the loom that runs across behind the front panel

grease_monkey

that sounds like what ive got it looks like the loom has been cut and joined all over the place

If its a normal XR3i loom the distributor and coil wires run down along the front valence with the headlight loom incorperated.

With the 16i loom the ignition loom is seperate from the main loom and runs along the back of the engine connecting to various sensors and of course the coils

hi have u got a picture of the loom atall cos am having problems with the bloke i got the engine from.
he is saying that he put a coil and distributor on because he says that the coils brake down/cut out while running.is this true

Will see if i can get a pic tomorrow

The coils have been known to be troublesome and for most people the only option was to fit a dizzy as ignition parts can be hard to find and expensive

mind you most can be found on ebay now

thanks that would be good .
have found part loom and controle module from a chap at ABC Motorsport
in horsham sussex (he had a couple or rs1600i's and loved them) he wants aprox £100 was hopeing to get this during the week.

If you're going to get this system working you'll also need the RS1600i flywheel and gearbox sensor.

You'll also need the get the hole precision drilled into the bottom of the gearbox to fit the sensor in, - the fiesta's box won't have the hole. These sensors can be an absolute nightmare and have been the cause of many rs1600i owners converting to a distributor.

Are you sure you want to ditch the Fiesta's EFI in favour of the older system used on a 1600i? You could put the head off your RS1600i on the Fiesta's original CVH with some work. The 1600i bottom end is standard XR3.

grease_monkey

thats all there mate just the controle module, coils and i think by the looks of it some of the wireing loom.
just trying to find out exactly what part of loom missing.
also do you need the module if running coil and distributor as that is what i was given with the engine

grease_monkey

forgot to say the engine has had the bottom end uprated i.e. reprofiled crank and is ment to have been rebored, also ment to have uprated camshaft.

MarkN

You don't need the ECU, sensor lead, twin coils, gearbox or any of that stuff if you're running a distributor. To be honest you don't need the 1600i loom either as you'd be using an XR3i setup.

Are you sure its a proper RS1600i lump? What's the part number cast in the head on the inlet side between cylinders 2 and 3?

grease_monkey

ill have a look tomorow and post the number up.

I have been reasured by the bloke that it is a genuine lump but will get number to be sure. What should the number be out of curiosity?

MarkN

Um, I can't remember off the top of my head I need to look it up. I'll dig it out in a bit.

Also you might want to take a look at the rockers and see if they have a hole above the lifter. Does it still have the solid lifters too?

grease_monkey

Ok I will strip id down and have a look got to do the cambelt on it anyway.

will try and take some pics aswell.

grease_monkey

just come back from the garage.

the head has got on it (1.6BRA) 81 sm6090
the block has on it : sm6015(same on xr2iblock) 81 DEA

its also got hydraulic lifters onit
the camshaft has got on it: between cylinders 1&2 cwc8134
between cylinders 2&3 c2 d2
on the distributor end BP285
not to sure if its a poss burton camshaft/kit/head.

Has the cylinder head got square or round exhaust ports? i believe that number is for the RSi cylinder head

Block doesnt really matter is its the same as any 1.6 CVH

BP285, think that might be a piper cam not sure?

P.S. i have pics of the wireing loom if your still interested

grease_monkey

the ports are flat at bottom and slightly rounded at top a bit like the xr2i ports.
am still intrested in photos.
have sent burton an email about camshaft

MarkN

Doesn't sound like an RS1600i cylinder head mate. I'm pretty sure the RS head has round ports and H81SM-6090-BRA is the number for a XR3i head. The head number for the RS1600i is H81SM-6090-AA.

BP285 is definately a piper cam though,- you can find the spec for it here: http://www.motorsportworld.co.uk/fra...-BL&PID=318166

To be honest it sounds like a tuned XR3i lump and an XR3i loom, - nothing wrong with that. If it was a genuine RS1600i cylinder head it would be a real result because they're very hard to find.

give jason a ring at jk performance

NEWTON

a number would be useful

grease_monkey

just been chating to old owner he says it was a genuie lump but the hed was exchanged when polished and ported .and was on coils but had probs with them so changed to a coil.
when took out of car seems to have cut a few wrong wires.

MarkN

Yes but an RS1600i lump is exactly the same as an XR3 lump. The only special bit is the head/cam etc. Without that you might as well have the bottom end from a 1.6GL.

The RS head already has larger ports and valves so exchaning a genuine head with the solid lifters, higher ratio rockers etc for a worked over XR3i head is a very curious move.

Quite often when someone buys a RS1600i lump it ultimately turns out to be an XR3i lump with the motorsport rocker cover on.[/i]
