I have seen a fair bit written about fitting a 2 ltr Focus Inlet and TB on a 2ltr Si but it is all fairly old and nothing appears to have come of anything.
Has anyone managed to get one fitted and working properly as I am thinking about fitting one instead of an RS1800 one for a number of reasons.
The RS1800 HO manifolds are hard to get hold of and generally cost the earth whereas I can get a focus manifold for about £40 complete with TB etc.
I know the RS1800 is the highest flowing option as far as standard fiesta manifolds go but surely a 2ltr Focus unit is going to be higher flowing still?
I understand that the ISCV and Throttle position sensors have to be modified from the fiesta ones so the voltages match and dont confuse the ECU. Any idea how?
Im going to have a go at getting one to work so any advise and insights any one has to get me started will be greatly appreciated.
