Radiator question for Seta "build"

[phenryiv1]

I am planning on the cam swap on my 88 Seta 325 (like there are any others!). I have a 9/87 build date (88 MY). All of the donor parts are from a 9/87 (also 88 MY) "i" with an auto.

I pulled the rad from an 88 "i" auto donor for my Seta build, and I was wondering whether hanging onto the radiator was a waste. If it will still work, that is cool.

Of course, my eta radiator seems to be fine...

So...between the "i" auto radiator (which was pretty clean) and my fully functional and clean eta (manual) radiator, which do I want to use?

It depends which cooling system you want to run. They use different water pumps and hose routing, and the expansion tank is on different sides of the engine bay. Most find the late model cooling system to be more efficient.
