Ordered the smaller setrab unit with fan to replace the oil cooler that was installed when I bought the car (pictures). The new setrab unit is way smaller than I thought it would be. In fact, it's about half the size of what's installed now. I'm pretty sure the bigger setrab unit with the double fans is too big for this space. Anyone see issues if I run two of these smaller units in series? That way I can install them staggered and will fit in that space quite nicely.

Yes, but running them in parallel is better.

(IMG:style_emoticons/default/agree.gif)

Running two units in series doubles the pressure drop. Running them in parallel cur the pressure drop in half but you should run identical units or oil will take the path of least resistance which is the larger cooler. You end up with reduced flow and cooling with a series installation. Sometimes less than a single cooler depending on the coolers used. Will not affect main engine oil pressure as the loi cooler circuit has a pressure bypass.
Question is how much cooling do you need? I have never liked the under body cooler installations fue to hot and low air flow. Adding a fan only provides air flow on part of the cooler due to the motor center and the area covered with a circle on a square. They are more effective in the airflow path with cool air.
