AC radiator -> oil cooler?
#3
What have you done to your car that makes you think you need more oil cooling? The stock coolers are far better than most oil coolers in modern cars. What are you oil temps now? Cooler oil is not always better either. The stock cooler also has a thermostat to keep the oil from getting too hot. You would have to eith run an aftermarket oil t-stat, or not run one at all which is not good. These are just a few things to think about BEFORE even considering if the AC condensor itself would even work.
