This thread takes me back! If you want to swap to either a 1.8 or 2L then don't bother, it's been covered plenty of times on here, just do a search!

I am not going to list everything but put simply the two engines are completely different, and it's a lot of work, the similarities between the two engines, that being the Zetec-SE and Zetec-E ends with the name!

The inlet and exhaust are on opposing sides for a start, then there is the suspension/management etc (The Zetec-E is heavier and is of alloy/iron construction) opposed to the all alloy/plastic design of Zetec-SE engine, like I say there is a lot more than this, the general consensus being you would only consider such a thing if you really liked your current car or have a donor for the parts, else just buy the bigger engine car outright!
