get the ecu first, it will have 1 or 2 codes on it, OFAC or OFAB, the engine loom that connects to the ecu must be the right one for the code on the ecu, something you have to take the word of, of the seller if on ebay, but the difference between the OFAC and OFAB is a few pin locations which can be moved, or you can conver the xr2i engine loom to suit the ecu.
also the injectprs you use must be right for the ecu running them, i forget the word im looking for but some injectors will not work with the FRST ecus, like cossie injecotres for example, they cannot ne used with FRST ECU so check the injectors you have will work, i would say but i am unsure tbh mate.
you will also need the map sensor to suit the ecu, again OFAC ior ofac and OFAB of ofab, but cossie one can be used if using ofab.
and fianly you will also need the turbo ACT (actual charge temp) sensor, if you dont, it will run like toss
The wiring loom is included so should fit.. Have looked at the differents in wiring and the almost none. 1) The driving speed sensor goes to pin 4 on fiesta and pin 3 on my escort.. Easy fix.. 2) There is a thing on the fiesta wiring diagram that my escort dont have. Co measure of some kind.. Need to find out what that is, and if it can drive without. But other than that there shouldnt be any differencies according to the wiring diagram..
According to the auction page the ECU is a Ofac.. It looks like the map sensor is included..
And for the injectors I read i page on fiestaturbo.com that said that 701 injectors should be used with a stage 2 chip (195 hk).. The ones i have are also high-ohm and nearly the same size (240 ccm vs 249 ccm)..
Do you have a link or picture of that "ACT (actual charge temp) sensor", where is it fitted original?
