1990 Oil filter housing..Does it matter which hole i use for turbo feed line?

[95EclipseGST]

In the attached pic it is shown with the turbo feed line at the top hole, on RRE's site it shows a digram to get the feed line from the bottom hole. Which one is best to use? Does it matter? Also there are two sensors shown in the pic. On my 95 GST i think i only have the bigger sensor shown at the bottom. What are these two sensors? Again RRE site shows my sensor shown mounted at the top which is different than this pic. Does it matter here which hole i use for the sensor? I dont think i have that smaller sensor, do i need one? If i dont need that smaller sensor "shown behind the turbo feed line mount" what thread size of bolt do i need to plug it? Thanks

Figure out a answer? I'm searching for the same thing now.

If you use the wrong one, you may end up using unfiltered oil. Just take a good look at it with the oil filter off, and you'll be able to tell which one is 'after the filter' and which one is 'before the filter'.

You use the bottom one. Not the one in use.

Makes sense. Any of the bottom ones are ok right? Unless that other one is just a sensor.

Thanks

^^^What he said. Also, the larger sensor you're talking about is the oil pressure sending unit. The one in the pic looks like it's for an aftermarket gauge. FYI- if your balance shafts are removed, i would suggest a restricter fitting before the oil feed line so you turbo doesn't see too much oil pressure.

I assume this is the right spot? It's a 1990.

Yes, that's the right spot. That is a filtered oil feed.

What about the one right next to it? The one right underneath the big after market sending unit, is that the factory oil pressure unit? Or is it another cap? I ask this because it doesn't seem to be connected to anything

Thats the oil thermostat valve for the oil cooler. It opens when it gets up to temp.
