Is it normal to have oil on the bottom of the turbo?
So I was doing an oil change and I decided to spend some time inspecting everything from underneath. Since I am having issues boosting the car past 4psi I figured what the hell, I'll look.
Anyways... there is fresh oil on the bottom of the turbo that faces the rear end (closest to transmission).
I wanted to know if that was normal or if my turbos are going bad/already bad.
They are the original turbos and the car has 64,500 mi.
Everything else is looking good (thank god).

Constant threat
The back turbo tends to want to leak around the oil return line. It is a bit of a bitch to fix, but can be done by removing the rear turbo intake, getting under the car with a long extension and 10mm socket on a ratchet.

Could this be effecting oil temperature too?
I think my turbos are junk to be honest.It sounds like air is rushing out while it spins up but I've never heard it on any other car or what a turbo sounds like (this is my first turb car).
I can only get 3-4 psi max and all of my hoses have been replaced and every single ~1" dia hose has screw clamps and every small silicon hose has been replaced and using nylon zip ties. Every bigger coupling has brand new silicon with large screw clamps.
losing my mind!

You honestly have just a boost leak mate,,, you can hear the air noise so there must be a leak somewhere (the oil leak you describe is on the 2nd turbo this wouldnt prevent you from building boost you would likely just smoke a bit under boost) keep searching for that boost leak,,,its within the primary set up-> check this link

The oil you're seeing is fairly typical for original, 14 year old twins. It might be a fixable problem (return line) and it might not be (seals).
The boost problem is not the turbos themselves--it's the control system, as RTS3GEN mentioned. You most likely have a problem with a solenoid, check valve or vacuum line. I believe Banzai Racing is out in your area, have them fix the problem for you, a silicone hose zip tie job would most likely be in order.
