I have just converted my XR2i into a fiesta turbo running a T3 and i have rebuilt the engine putting new gaskets on the head ect ect
i have got it started and running fine then suddenly after about 20 seconds it made a loud whistling noise which slowly got louder coming from the head which sounds like a air leak, i had a listen and i couldnt locat were it was coming from, i then started to check every thing was attached e,g the brake pipe, idle valve pipe, inlet pipes, boost hoses ect ect thinking not much of it once it was warm i tryed to give it a rev, it wouldnt rev properly and when i put my foot down it just trys to cut out and wont properly rev or come on boost and when it dose rev
(which is done by very slowly putting your foot down) it gets to about 4500 and stops and starts to cut out, it also wont idle properly
i have changed the wiring it need e,g has frst map sensor and ECU
any ideas would be much appreciated and could help greatly

oh it wont drive either as you bring up the clutch with revs it has no chance and just dies

You are aware that the FRST had 2 different engine management systems don't you? Both were Fords EEC4 but it came in OFAB and OFAC and the two aren't interchangable.

i have just stripped down the inlet manifold and cleaned it up and put it back on, seems sorted no more whistle but it is has now come to my knowlage that it is over fueling MASSIVELY and the large amout of fuel is blowing out the spark!, i am going to have a fiddle try some diffrent ECU's and stuff and see how it gose tommorow at least that bloody whistling noise has gone and its revving (even if it dose us a 5ers worth in one rev lol

Nice one m8 cheers for that i only had OFAB ecu's i tried a OFAC and the car is running alopt better but it still isnt running correct and will not rev properly
