Lower than expected oil pressure
On my Miata I'm using a BLOX Oil Filter Relocation with a 19-row oil cooler that was fairly inexpensive and -10 AN hoses throughout, as well as a Boundary Engineering Stage 2+ oil pump. I am using an OEM-sized Mobil 1 oil filter on the remote oil filter block. I also have VVT and a turbo as oil-using devices.
I'm experiencing lower than expected oil pressures at higher engine speeds. I would expect to be about 60+, but it doesn't seem to exceed 45 PSI. Would either of the components be an issue regarding pressure drop or restriction?
BE has said that some oil coolers can cause as much as 20 PSI of pressure drop, large bearing tolerances can cause this problem as well.
Later I'm going to join the oil cooler hoses and see if that helps eliminate some of the drop.

Order 2 -10an caps online. Cap the 2 hookups for the oil cooler lines. See if pressure goes back then.
I am not a fan of relocation kits, and cheap sandwich plates. I lost 2 built motors to a cheap glowshift plate that got clogged.
