You have a stock oil cooler already. Even though you're upgrading the turbo (and probably IP) and will be making more heat and power, you should hold off on adding anything to the stock system until you verify that the stock cooler is overwhelmed.
If it isn't overwhelmed:
Leave the condenser in place for future A/C repair
Remove the condenser for room and weight reduction
Remove it and add a good size trans cooler in its place
If the stock cooler IS overwhelmed, remove the condenser and install a bigger purpose-built oil cooler along with a good sized trans cooler.
Like you said, there are 8 liters of oil in the sump. That's a lot of heat soak capacity for the oil and the cooler adds to that greatly by rejecting heat constantly.
Like Mxfrank said, oil that's too cold is way worse than oil that is too hot.

The car is currently running without an engine oil cooler - the previous owner I think damaged the stock cooler so just had it looped. The car already has the standard transmission cooler and I can feel that the cooler does get slightly warm after a drive meaning that it must be working ok.
It was just an idea about using the air con condenser, I guess that as its thin and has very small pipes it would struggle to run oil through it - I thought I would just ask about it as its not currently being used. The aircon system must have a leak somewhere as it has no pressure - the passenger side seems to have had some sort of stone impact (or maybe an animal) as the intercooler was holed, the oil cooler was bypassed and there is a dent on the underside but only on that side.
I am tempted to simply remove it and store it for a later date if I do decide to fix it although thinking about removing the air con pump as I know that has a fair weight to it as well - not like AC is really needed in the UK!
