As title whats required to do this and what are thebenifits etc? also if i had a FRST Head and EFI inlet / fuel rail would these go on an S2 block ok ?

 

frst loom,ecu,cps sensor,head,inlet,injectors,ignition(edis 4) Something like that.

 

also need the efi throttle cable and could also use a full 3i loom instead of the fiesta you just have to swop some wires around plus it looks neater as everything is where it should be plus the map sensor has to match to ecu try rsbible.co.uk as there is a guide to this for the s1 and s2
