Unless you have a grand going spare, I'd not bother thinking about it too much...basically you need a Fiesta Turbo, and transplant the engine and ECU etc.
Converting a RST block and head to EFI isn't going to be worth it.
You could do Zetec Turbo for a better price these days.

i have 4sale a full frst management setup (loom, ecu,efi unit,MAP sensor, plugin 15psi chip (reflashable to any spec i think) if it helps any1
then just need the 1.8 cvh cps reallt i would think, i just fitter frst engine and management to mine but goin back to mfi now a special lump has surfaced
also have a frst full engine 4sale to0

fook me , hear we go again ,
1 last time i will say whats roughly needed ,
Will a mod PLEASE PLEASE add some conversion notes to the technical archive .
For starters a FRST engine and head will be needed , block so u have a Crank position sensor and the head/ inlet so u can use electronic injectors ,
a cheeting way is to use a XR2i or a Xr3i ( efi ) engine and fit low comp pistons or a set of standard RST ones .
The Flywheel from these EFI engines will also be needed ,
The best loom to use is a XR3i ( efi ) escort one , the whole loo will fit straight into you RSTand will be the easiest to fit ,
Dont forget youll need the clocks aswell as the rev counter will only be half true if you use the ERST standard ones ( EFI uses wasted spark and only measures 2 of the sparks so to speek)
Now u have the new loom their are 2 wires to change ,
firstly find pin 27 in the main ecu plug , brown wire !!!! move this to pin 8 ,
Next go to the EDIS module and find the second wire in , ( blue and yellow , ) either remove this or cut the wire and tape it up .
that is the loom now up to FRST spec .
Youll obviously need a Fiesta ECU , OFAC or OFAB , and a map sensor ( OFAC and OFAB ae different so get the right one )
U need the FRST inlet charge temop sensor aswell ( available from ford) these are NOT THE SAME as the rst ones , U NEED THE FRST ONE !!!!!!!!!!!!!!!!!!!!!
Plug it all in , plumb all the engine in and turn the key ,
it realy is that simple , if you want any more info please feel free to call on the number below .
oh forgot to say thet the turbo will need to have a return plumbed in
hope this helps guys

Converting a EFI XR3i or XR21 is much easier than doing a ERST to EFI - due to the reasons Lee just described. It's still gonna cost you over 500 quid, unless you get a OFAC/OFAB, turbo, hosing and piston set cheap.
You don't have to do it the hard way. You could just always get a complete cvh efi inlet, bigger injectors and a management like the under 100Ł Megasquirt and your done. The inlet fits the head nicely without any adaptor plates. Just grind away a little material from the head.

Adapter plate for the efi manifold, save grinding the head, and getting swarf in the bores.
Just need to get the 5-6 wires for the multi plug sorted
