Yeah, the setup is different completely because the intercooler coolant radiator is much bigger upfront, which displaces the steering oil cooler to be pushed up front, the Engine Oil Cooler is bigger, the Coolant radiator in front of the driver wheel is also bigger but that one is shared with the M5/M6. Because that cooler is bigger, the Aux Pump is not pushed to be behind the main radiator and that is the location where the transmission oil cooler is on the regular n63.. so totally modified front end..Just makes you realize how extensive the development process is for Alpina as compared to any other tuner out there. Oh the radiator Fan is also 1000W just like the M5/M6.. but that is one you can retrofit easily in any n63 to help cool faster.
I'm emailing you some Alpina docs that may prove useful as you go about this project
