There are some solid suggestions in the above posts, but I'll add that it is conventional to change the oil shortly after a rebuild. The idea is to remove any desbris which may have been left behind in the various engine parts or oil lines. 500 -1000 miles is about normal.

You should be running a good quality xx-50 weight oil if you track the car (you quoted DEs). Synthetics are good as they don't burn inside the turbo. xx-40 weight will work too, but I don't think many turbo owners would support a lighter weight.

If the oil is very thin, there is a potential that the oil flow rate through the turbo exceeds the scavenge pumps ability. The scavenge pump is a positive displacement pump and runs proportionate to engine speed.

The can under your turbo is an accumulator which allows the turbo to gravity drain. The oil is removed from the can by your scavenge pump. Your accumulator is not stock, but appears conventional for all the aftermarker ones used to fit in conjuction with performance heat exchangers. They don't fail.
