Have you had a price from ford?
im sure youve allready checked, but will the 2.0 oil pump fit and allow you to get the oil filter on/ off with the angle its at? as in an escort you have to use a stubby oil filter if you go with the 2.0 oil pump. Id deffinatly go with a escort 1.8 zetec oil pump as it allows you to fit the normal size oil filters, as i say thats from expereince with escorts, just something to think about
