All the 55 cars use the same fluid routing, the engine coolant is the intercooler coolant the circuits are tied together just below the coolant reservoir. When I started looking at 113K cars I originally was looking at 211s as they are another poster on my bedroom wall car from when I was a kid and learning the to- dos for mods splitting the IC circuit was always high on the must do list and looking at why it makes sense. The interchiller is definitely the hold my beer and watch this way to go about cooling but where i'm at with the car and where my end goals are for it it was bound to get to that point eventually. I live in the south so I don't know if we get Aussie hot but our summers definitely hold there own so I understand the focus on keeping the car happy. FI is from your neck of the woods if you had never looked into the system so if it works for y'all i'm confident it will survive Georgia.
