I spoke to Jez about this actually. Sounds wise. Also about he frozenboost, and actually that my heat issues only started when I got the oil cooler! That thing is a huge heat pump straight into the inlet.
Nick has managed to fit his frozen boost .... May well be worth chatting to him about the install . I'll let you know how the rest of the work goes with mine as it would be beneficial for yours also if it all works .
Where is your oil cooler located ? On the right as you look at the front , directly under the air filters?
