Go find a Toledo 2.0 8V - I have a set of fans off one on my radiator in my Syncro. Instead of the rubber flaps etc it allows airflow through the whole radiator. Mine's mounted up on a radiator from an ABF G3, which took a little work.
Next up is an oil cooler, as the Golf1 GTI doesn't fit on a 2.0 block, annoyingly.
