to be honest i don't think that ford are going that way with their engines, they are going for tighter tollerances, take for example the st focus, it has (i think) 4 camshaft sensors and 2 crank sensors. this is all because of this variable valve timing malarky. then to get this power through to the road they use esp, which is great for keeping traction going round a corner, but sometimes you can go faster with it off (think of it as more of a saftey measure). god i could talk about work all day!
always looking for those bigger bunches of bananas!
