Well im prepping my car for a Subaru STi motor actually and believe that the three radiator setup from a boxster may work great for it. My friend has already done the swap but cut out the front tub to place a large Ron Davis Radiator there. Im hoping not to cut anything and maybe modify the radiators to work accordingly. The 3 radiator setup looks like it will be sufficient too.

Another porsche member has made custom radiators for his GT3 cup motor, but they are very pricey:
