This is taken from the 'How-To' section of the forums 1.6/1.8 zetec - 2.0 zetec One of the most popular swaps due to how easy it is and it gives you the power you would've expected the GTi's to have had [136ps]. Although I did my 1st 2l conversion without any prior experience in stripping engines, I wouldnt advise it to anyone who isn't completely confident with what they're doing. I personally had the 'timing belt fear' but as long as everythings marked and instructions followed its relatively easy and very straight forward - albeit time consuming. Parts needed 2.0 zetec [silvertop] engine - from mk1 mondeo. new cam belt kit (optional[advised]) escort water pump - either from an old 1.6/1.8 engine, or a new one [advised] escort oil pump (optional[advised]) - you can use the mondeo one along with a smaller oil filter but you may have clearance issues due to the angle the mondeo pump comes out at. [new one advised] escort/fiesta zetec sump and oil pick up. escort/fiesta zetec manifolds. 2l pre pats ECU (early mk1 mondeo). escort/fiesta zetec flywheel and crank sensor. Other info You may as well use new bits while you have everything off. You can keep your own gearbox and pretty much everything else from your existing setup inc radiator, pipework and loom (although the ECU wires need a little modifying, theres a how to guide in the forum) Price You can get a 2l engine for around the same price as a 1.8 (£150), after this its pretty much up to yourself how much it costs. i always use parts from the local motor factors rather than ford parts and i very rarely have problems. All in, including all the parts ive listed above as [advised], expect this conversion to cost circa £350 if you do it all yourself and buy motor factors parts.
