Won't be 2L as this is a very involved and difficult conversion, the 1600 in the MK1 and 2 is EXACTLY the same engine, don't let the "Duratec" name fool you. It is however avaliable in two power outputs 100HP which is the same as your original engine or with VCT which gives an extra 15HP and so 115HP, I suspect you have the former otherwise you would find you would have spare wiring etc, if you did have the latter then you need the additional wiring etc and different ECU.

In any case the fact you have the EML on shows something is wrong, check you have reconnected all the sensors.
