most get rid of some of the front slam pannel just beside the headlights and make up a new bracket to hold the rad and move it out a bit. how much is depending on which rad you are using. my presumtion is the origonal rs turbo rad???? there are threads on the kaklub which show various members using the standard rs. they dont have to move it much forward but a whole new bracket is usually made for the rad and the bonnet catch. there was a white rally ka in performance ford a while back running a 1700 puma which had the same job done look that up.
