I have just done a search for the XR3i manifold conversion for aftermarket EFI, but can't find anything relating to my question . Has anybody got pics or sep by step guid how to fix efi injectors to the inlet?

Ahh... ok. Yeah deffo put the pics up when you get it back. The Fiesta EFI manifold looks so restrictive and you can see it on the rolling road too. when i get my graphs i will post them up.

I would look into getting some proper steel sleeves made and pressed in like mine has. The alloy these manifolds are made from is utter shite and can/will cause sealing issues. I drilled my old sandwich plate on my previous manifold and although it worked I was shocked by how brittle and 'flakey' the alloy was.

Tis argument has been going on for ages! Think about why ford would spend serious money on developing both cvh turbo inlets to go over the engine compared to xr3i. With risk of air temps etc! surely the must be a reason as would of been cheaper to us xr3i i guess. But due to technology now i am sure aftermarket one flow better if that makes any sense

Less of a restriction so increased VE meaning more power and torque at a lower boost preassure.

I've done that. Quite easy job.
A friend of mine redrilled the holes in the sandwich plate, so I don't have any pictures of this. EFI injectors are bigger than MFI ones, so you'll have to remove some material at the inlet manifold. And maybe you'll have to use injectors with a different (smaller) spray angle, because they're not so close to the inlet valve like they are on EFI CVHs (XR2i, FRST, PTE...)
I use an RS1600i inlet, so I can use the ERST throttle body which already has mounting brackets for a TPS. You can't use the ERST TPS for any aftermarket injection. It just works with the KE-Jetronic. My trottle body is an RS1600i one, with the bigger flap and modified RST parts to use a TPS.
You might be not able to use the RS1600i inlet manifold because of your RHD brake setup and the hoses might hit the brake fluid reservoir.
The MK3 XR3i uses the same throttle body type like the RSi/RST (4 stud pattern) but the inlet is the same as it is on MK4 MFI ones. Ford simply made a sandwich plate. So try to get one of them to use a RST throtte body with the XR3i inlet. Or make a custom one to use a different throttle body.

I just made two brackets to secure the fuel rail and simply bolted them onto the inlet. Now I've got to remove the whole inlet to get the rail or the injectors out, but that don't happen that often

Inlet needs slight machining in two places like this for the body on the injector to sit in as they catch the manifold.

I had the fuel rail mounted as so, but was later told engine vibrations could cause this to crack as theres not much meat to weld to.

You'll notice the throttle body plate has also been re angled so pipework doesnt go behind the master cylinder or have to use a nastey 90 degree bend etc.

Good effort. The Master Cylinder on the XR2 appears to be much lower than the ERST setup. You would never be able to route a pipe directly over the top like that, although mines got a Bias Box so different again. With the new intercooler, though, my inlet piping will the very different.

That's because of the RHD setup with brake bar. Usually the whole unit sits much lower on LHD cars. That's why XR3i inlet and the hose look so strange. To fit the hose between servo and reservoir. Much easier on our cars

For those of you who only want around 200bhp then of course it is fine, but anyone wanting closer to 300bhp or more a custom inlet is a massive advantage, Jimbo Gibbs for example made huge gains by changing from an EFi inlet to a custom one not to mention the fact that he had an engine failure due to 2&3 running lean because of the EFi's poor design.
You only have to look at it to see why it's bad, just count the number of 90deg bends your intake charge has to go round after exiting the IC top hose, then look at any custom manifold setup and compare... There is a reason none of the big power boys run a stock EFi manifold.

Couldnt you of just ported it properly karlos?
On olllies s1 they use a rs turbo inlet still (think it was last time i saw it) and id imagine karl will have done a fair amount of work to it tho but still we all know how powerfull that car was/is

A friend of mine had a 1850 CVH with RS1600i inlet, RS1600i throttle body, WM management and WM tps fitted to the throttle body using RST throttle parts. (RS1600i don't have a tps pickup). You also could use the RST tb. Fits the RS1600i inlet and is just 5 mm smaller than the RSi one and as big as the 3i one. TPS is much easier to fit then as the RST tb has got the pickup and mounting brackets.

Sorry to bring up an old thread, but I'm in the middle of TRYING to sort out an MFi to EFi manifold and was just wondering if Muz had any more pics of how the fuel rail is bolted to the manifold, also does it the manifold work well, i'm only going 195 chip etc so not looking for any stupid power figures.
