I would not suggest using a Ford Probe intercooler. It is designed for a 2.4 liter.
Generally speaking, factory intercoolers are too small to begin with. They just throw in an intercooler that will fit(for packaging purposes),not one that will cool the best.
I know what your saying that it will fit perfect for your car,,,, but take it from me,,,, it is too small. A Volvo intercooler is as big as the radiator,it is overkill pretty much for there size engines.
You can pick them up at junkyards & tell them it is a radiator,(usually radiators are cheaper than an intercooler.
But if you want to spend a little more for a new intercooler, Ebay has tons ,,,just look for a bar & plate design & one with the flow requirements you are looking for with the inlet & outlets where you want them. My two cents
