Radiator efficiency

[mistamidget]

I'm converting a stock CE GLI manual sedan into a GLXi auto sedan just for a project (for something to do now breaking bad is finished)
The car I'm converting from had it's radiator destroyed by endo'ing into a towbar but I've got a CM5A auto radiator in an EVO that I want to put in because I don't need an auto radiator in the EVO.
The earlier and current radiators are a bolt in fit but the NA CE2 radiator is way thinner.
Is this because the newer tech radiators are more efficient or because NA doesn't need better cooling than turbo?
Would a standard CE2 radiator be good enough in an EVO in the OZ climate?

I would say that the turbo would need the bigger radiator.
Thought the smaller one will probably suffice. Certainly to help the smaller radiator, I would install a trans cooler.

I had a thinner radiator in my old GSR temporarily....It didnt cope real well with heat so I would advise against it.

Hmm, might look for a auto radiator then and keep the original.
Thanks.

Good idea :thumbsup:

EVO and GSR radiators use a copper core and are very heavy.
Newer radiators use a thin alloy core and are very light.
Both have their advantages and disadvantages.
But don't be put off by a thinner alloy radiator as a good design can cool just as effectively as thicker core copper radiator anyway.
