for the oil feed line into the HX40, what AN size would you guys recommend I use for the oil feed? I was thinking -2 since the hose ID of that is 1/8" (0.125)? from information I found online, the HX40 is supposed to get 70psi max and 7psi min, with recommended 2 - 2.5bar (28 to 35psi) around load. would a -2AN choke the flow to the turbo?

3/32" restrictor and your good. 15psi at idle, 70psi max.

My -4AN oil feed line was reading well over 70psi at high rpm without a restrictor. I'm a specs guy, so put a gauge on the line and checked it out for myself. Also, I believe there is a flow spec in addition to the pressure spec. -2AN (1/8") may very well restrict the flow.
