youve nothing to worry about mate, you can either run the chargecooler set up or the intercooler set up, aslong as youve got one you will be ok! i bought my car with no FMIC or chargecooler rad and i ran my car for a week as my car didnt come with one!

Both set ups only deal with the turbo, a chargecooler uses water to cool the air coming into the turbo, an intercooler just uses the air.

Most people prefer the chargecooler set up if your just using your car normally with a bit of spirited driving as it is more than ample, people say that with the intercooler set up the car can be laggier, my friend ran one on hers and it was lightly modded and it just wouldnt boost properly.
