Bad news my friend, unless its your oil pressure sender that came with the aftermarket oil pressure gauge that maybe failing (not reading the pressure accurately). If it's not the culprit, then it is either the oil pump or the rod/main bearing clearances that are out of specs. Do not drive the car until you figure it or you may cause more internal damage to the turbo bearings and the shaft, crankshaft journals, cam lobes, rods (small ends and eventually large ends once the rod bearing(s) spin(s)), and piston wrist pins.
Be mindful, if you simply replace the oil pump but the problem is with the bearing clearances (rod or main bearing(s) falling apart - thinning), you will end-up damaging the new oil pump. So the very first thing you need to do is to remove the oil pan and inspect inside it. Look for metal shavings (appx. size between 1/32" and 1/16"). There should be a bunch (100s of metal pieces). These would not come out during oil change. You need to remove the oil pan.
No metal particles found? At this point I would confirm whether or not the oil sending unit on the aftermarket gauge is functioning properly. If its not the culprit, then proceed with replacing the oil pump. Do not purchase used pump or a pump without a known brand. I suggest you spend the extra money and get an OEM Honda oil pump. Should be around $175 on Ebay.
If you do find metal particles on the bottom of the oil pan, then its time to take the engine out and rebuild it. Remember to hot tank it prior to re-assembly or your new engine will fail shortly after from previous contamination.
