You cannot 'move' or put a larger intercooler into the powerworks kit - the CAC (Charge Air Cooler) is inside the intake manifold and there is no room for a larger CAC brick.
I suppose a larger LTR (Low-Temp Radiator) could be used out in front, but you run the risk of slamming it on every low object in the road.
The powerworks intercooling system can lower charge air temp from 300 deg F to 88 deg F ... about the only thing you could do do get it cooler than that (which isn't really necessary) is to run the CAC supply line thru an ice container of some sort ... but why do that if it isn't necessary?
If you're going from a bone-stock Zetec to a 220HP car you'll have a lot to relearn in driving technique to really use it.
With the powerworks kit, you also get a very robust calibration ... better than OE MPG and driveability and no issues starting/driving in sub-zero/extremely hot weather or at high altitudes. There is some extra potential in the calibration ... you just run the risk of running on the ragged edge (and voiding your warranty).
