Haha! well, not spectaculair news, but some small steps are sometimes needed as well to complete a job.
So, I now finally have the oil feed for the Borg turbo complete
This was quite a hassle. Why? see for yourself:
Left to right: 1/4" NPT is the thread size into the turbo, so I needed a 1/4" NPT to 1/8"NPT adapter, 1/8"NPT male to 1/8"NPT with 0.165" restrictor (1.5mm), 1/8"NPT to inverted flare female connection and M10x1.0 inner thread, M10x1.0 male and inverted flare 'copper' 5mm (~3/16") brake line.
This connects then to a goodyear braided oil line (with M10x1.0 ends) that feeds of the oil pressure connection on the engine case (with a 'T' for a oil pressure sensor)
Next job will be the oil drainage adapter, which will have to be made from scratch (from hi-grade alu) for my -12 line... (all adapters for sale are -10...)
