Whats the size of turbo coolant line

[KWimmer]

Just making up some new lines for my hybrid installation. Anyone know the factory size of the turbo coolant line. On a previous installation I ran 8AN braided line. After thinking about it though,that just allows more flow through the turbo which really doesnt need it and less flow through the engine. The original fitting looks more like 6AN.

Thanks

If you mean the one that goes from the head to the turbo it's 1/2" i.d. hose. If you're ever in a bind (stranded) garden hose is the same size.
