Your caps lock button seems to be stuck on.
The main reason why chargecoolers aren't used very much on Imprezas is because air-air intercoolers are considerably easier to implement, and ultimately tend to be more efficient.
A couple of people have tried them as specials, but that's about your lot.

Thanks the charge cooler he has is fits as direct replacement to the standard intercooler but i think the benifits of a charge cooler is that you can tweak its cooling effiency simply by changing the capacity of the water system ie the bigger the water radiator the higher the cooling capacity !where as with an intercooler what you see is what you get what do you think ?

You can't optimise a charge cooling system simply by increasing the size of the rad. To get the most out of a bigger rad you'd also need to increase the water flow rate, which would need a higher capacity pump, etc. etc. You can also increase the efficiency of an air-air intercooler simply by making it bigger, so in this respect chargecooling doesn't give you anything an intercooler doesn't.
When you take out all the common denominators, the only real advantage a chargecooling system can offer is the potential for a shorter induction path.
If you want to run big boost, sooner or later the efficiency of the top mounted intercooler becomes a limiting factor. Thus, you have to go to an FMIC, which entails a longer induction tract to link everything up.
With a chargecooled system, you can keep the core itself in the top mount position while moving the rad to the front, thus keeping the induction tract pipework length to a minimum. To be honest it's nowhere near enough of an advantage to outweigh the disadvantages...
