1G Adding a 2nd oil pressure sensor

[dsmBear]

What are the 3 extra ports for? I imagine the 2 on the side would be for the external oil cooler, but the one facing downwards, it has a hexplug in it, could I install an oil pressure sensor their with out removing the factory idiot light and gauge

The one facing downwards and towards the front of the car would be fine if you won't be feeding the turbo from the housing, as would either of those for the oil cooler if you aren't running one.

okay great I can't fit the adapter and the sensor in the Allen plug one in the front because the subframe arm gets in the way, so I can run it out of the oil cooler lines? But what I'd I plan on adding an oil cooler could I run it out of the bug 27m bolt on the back? My lilpressure sensor is 1/8th not thread and I have an adapter to 1/8bpt

I don't know which port you are referring to, specifically. On the "back", as you say, there is the large port that we can see in the picture you've provided, just down and to the right of the return port for the oil cooler. That is the oil cooler bypass valve. The other port that is further "back" and not pictured is the oil pressure relief valve. I wouldn't recommend tampering with either of those.

You might consider drilling/tapping the housing on the flat round just above the two lower mounting bolts (circled below). Other options are to use a T at the same port for the pressure gauge sender or inline with the oil cooler feed.

On all turbo ofh there should be an oil feed port (for turbo), dummy light port, and oil pressure port. Do not use the other "ports" unless yours is like the picture above and has fittings for an external oil cooler as those other ports are valves to help control oil pressure.. (Newer models use water cooled oil cooler (sandwich adapter)). A t fitting or using your dummy light port is your best option. The dummy port tells you when your oil pressure is low (typically low oil) so as long as you check your oil regularly and have a oil pressure gauge you'll be fine. I prefer to manually monitor verse a sensor monitor for me.
