Car looks very nice , your doing some good additions. No so sure you will be able to fit the Ecoboost Engine in there , without most of the wiring loom and modules and power train , i would imagine it would be a very large project to undertake such a task. But if you manage it post a fitting guide i'm sure people would like to see how it turns out.
I know it could be a large project, but where is the fun if it all just bolts on? The only thing that worries me is the electronics, but I have a friend who could make it work
EDIT: I was thinking of a 148 bhp 1.6 ecoboost swap, because it has enough power,and does not require complicated power train modifications
That is it for now, I still need to decide if I am going to keep the car (if so, I will do a full engine swap to a 1.6 ecoboost from the Focus, do a full suspension/brakes upgrade, and Focus RS Recaro seats), or am I going to sell the car in 2014, and buy something else ( BMW M5 E39, Focus mk2 ST, Impreza WRX Sti should do the trick)
