We'll see about the rad overflow bottle. I don't expect to have to move or modify it. Cold side piping isn't 100% yet but I still want to see if it's even feasible to go under the headlight. The pipe fits, but I don't think the pipe and v-band will fit through that hole.
As for the pipe routing, the way the VF52 is, the hot side hooks in right by the turbo coolant reservoir, and heads straight back to the intake area from there, so it never is even over the turbo (well it's over the compressor), then down do the core, and back up the driver's side for the cold pipe. I'll either go through the washer reservoir area, or between the timing cover and rad fans. Then it'll go along the top of the driver's side head between the battery/engine and then curve into the throttle body hose.
I may need to do something at that spot since the TB hose seems to be about 2.75" and my pipe is 2.5". I can probably just order a 2.75 -> 2.5" silicon hose and build the pipe to fit where the hose will end at. I don't need to waste money on the AVO one designed to fit the stock TMIC location.
