[240 D24T] Which IC and better radiator
 

I have a problem with overheating the engine under load and I want to change a oe radiator from D24 for a better one. Are these from 7/9 series with d24tic are better more ? Maybe some of the other cars fit p&p?
Also I want to put an intercooler, I thought about the factory from 7/9 series, but I would prefer some one-sided. May know that the car had and could be used for our diesel ?
Thanks in advance and best regards:)

I'm not sure about the 9 series but I know for a fact the 7 series radiator is miles ahead of the 240 one. I'm in the process of moving everything over from 740 to 240. It's not easy, and you have to be willing to cut. But after driving the 240 all summer [2013] and getting the 740 last spring and driving it all year even through many states and Chicago traffic never even kinda got hot.So much of an improvement. But you need custom lines and to cut some of the rad support away to make it all work. It's worth it tho.
