Appreciate your observations.
Makes sense to try and move the turbo oil feed line away from the turbine housing. Yes I am going to have to get some form of heat shielding happening. I have a border A2A intercooler to go on top of this engine as well to think about so the shielding and its configuration will be complex.
The studs that hold the turbo to the manifold are the ones the PO fitted. He went a bit overboard with high tensile bolts and there lengths in several locations.
Yes engine is a Gen 2 and having never dealt with so much stainless steel braded hoses before assumed that the oil cooler pipes would have been of the correct type of hose. How did you pick they were coolant pipes?
I am very pleased you noticed this. I just assumed the PO new what he was using.
