the frs pistons will not fit into a 1.8 block this is due to bore size and i dont beleive it is possible to over bore the 1.8 to suit,
the heads are specific to each engine, the 1.8,2.0 and RS engine all have diferent heads, this shouldnt be too much of a problem, but to be honest the main point you should look at is the gearbox in the 1.8 focus its only the IB5 which is not the strongest by a good way, the 2.0 came with the stronger MTX75 box, and the RS has un uprated version of the MTX75
if i was you id go for a full FRS conversion, so many little things you need to do to get boost ona 1.8 the time and money it will take you are best just going for a full conversion i think,
cheers for clearing some things up would the 2.0 head mate to the 1.8 bottom end or are the the same bottom with jsut diffrent head? and been looking round the pistons for the 1.8 are 85mm and the 2.0 use 86mm so surly could bore the 1mm diffrence out mayb
and as for boxes looked into that two and yes i have got the ib5 box does the mtx75 box mate up to the 1.8 flywheel or would that have to be changed for the 2.0 if that was the case would just got for upgraded and lighter also can get a bc box for the older zetec engines from the gearboxman which comes with a quif lsd two
just after look at the manifolds again i am nearly 100% sure that the focus rs manifold will be a direct fit if i then went for some upgraded pistons and mayb rods upgraded cams focus rs inlet and injectors and then somethink like a Megasquirt ECU and a front mount intercooler would this be enuff for small boost upgrade apart from the box
