"Radiators. No amount of tweaking the rest of the cooling system will help if there simply isn’t enough cooling capacity in the radiator. Water capacity used to be the answer, hence the production of four-core radiators. It’s possible the improvement in cooling was a product of more surface area created by the extra tubes, but the inefficient airflow through the congested radiator area reduced its ultimate effectiveness. In reality, effective surface area’s the answer, and why the latest after-market, super-efficient two-core radiators are the best"i think you will find it doesnt matter how many cores you have, its the fin arrangement that gives the rad the cooling efficiency.
as for the rad, i would go for it. if it doesnt cope or last then you will know for next time.
please read the following, i think it will give you a better understanding of cooling a mini engine

chappy: as for the welds, they are a bit chunky but are strong. had a mate who makes aluminium rads look at it and for him to make one with so-called perfect welds, would cost in the region of £250-300. What counts for me is that it works and to be honest it actually looks really good in the car
hence why fin arrangement is most important!
good article though
