Ignore my comments/questions about excess pressure, but I still reckon its a flow issue.

To save you pulling yours apart, the standard metal extension fitting on that turbo has a 4mm internal diameter, and the orifice into the turbo body itself is 3mm.
In my T25 journal bearing install the banjo bolt has a 1.5mm orifice. I'm using one of these:

The oil pressure issue I'm going to assume is a faulty sender - the mechanical gauge is giving the same readings as the engine did when it was in the range rover, and mechanical gauges are pretty foolproof.
Hooking up the pyro and boost gauge now, with Damien help going to tune the engine in a bit better and see how we go.
