the 16v one is a bit small, you might have to think about upgrading to an 8v item! The 16v ones are double cored though so you may be ok, but I'd upgrade to a 2 speed fan at least!
On the 'other' forums the track day guys get good results from the 8v rads. If you do go for an 8v rad you may need the hoses to go with it though! Oh and be aware that the lower rad pipe from the ABF may not work becasue the thermostat elbow is different on MK3s, but fit your old MK2 one and you should be reet. Might as well put a new stat & seal in while yr there
