Engine block is the same, some small head differences (smaller chain teeth) but same cam profile, UIM and LIM are the same. The engine is more refined due to dual mass flywheel and more exhaust boxes and longer route. Exhaust goes over to one side as if to exit but then comes across the back and exits on the other side. Quoted power is the same.
I've put old shape mondeo heads (I'd had then reworked on a previous car) and SVT intake and throttle body on mine so far, SVT cams next, headers would be nice at the same time, hence the question.
