Another point to note on the mounting, is that the thermostat is making cooling decisions based on engine need/load, so its input (ie. the feed from the engine) should be short in order for it to make those decisions in a timely manner.
Also, think of cold starts; when the cooler is out of circuit, the scavenge pump is pushing barely warm oil back into the external tank; the longer the "engine > Tstat > oil tank" loop is, the more loading the scavenge pumps faces.
I have seen a number of remote oil cooler implementations with the MoCal located at the front of the car; not convinced these were well thought out. Look at where the Tstat sits on factory 911 models with remote oil coolers - close to the tank & engine.

Thanks Tony, for ease I was going to mount it in the trunk but after your statement I will make the loop in the engine bay.
Makes sense Andy, I didn't think about cold oil sitting and having narrow passages causing more force to be applied.
