Heating problem
 

Ok so I just swapped my sohc 1.5 out of my 93 civic hatch dx for an b18c1 gsr, the engine runs fine but gets hot pretty quick and temp gets to be to high. I have the stock radiator from the 1.5 still in because everybody said it would work but I'm starting to think I need a bigger radiator to support the gsr. I already replaced thermostat, temp switch, fan is working, and the water pump seems to be working. So my question is what is compatible for bigger radiator to help out.... I hear it's a del sol radiator but what year and model? Any help would be greatly appreciated.
