Article on: Oil Pressure Gauge
I purchased
Omori for my gauges. Omori can customize the gauges to stock WRX look. After
wiring them up, the gauges are VERY close. I am a pleased customer.

However, they are REALLY expensive, so I sourced them from Malaysia.

You will have to email them. It will take a little over a month to get them
manufactured then delivered. Michael Pang (who works for Omori Malaysia) was
very pleasant to deal with.
I purchased the 52mm gauges (60mm is too big for me and the size of the Defi pod
scares me), so the oem gauge pod won't fit. So I turned to Derres who makes a
face for 52mm gauges and dremels the oem pod to fit too.

The face plate is very nicely done. Perfect fit for 52mm gauges.
Now, to see how to install the oil pressure gauge sender, see this thread.

I would recommend you to read from the end of the thread, b/c this thread is
long and confusing from the beginning.
I haven't installed the sender yet, but prolly within the next week.

I just
installed the oil pressure sender for my Omori electrical oil pressure gauge. I
chose to use the second oil plug in the engine block instead of T'ing the oem
oil sending under the alternator. The second oil plug is under the intercooler.
You must remove the intercooler to get at this plug.
what you'll need:
12mm socket wrench
flathead screw driver
17mm crow's foot adapter
straight wrench (for crow's foot adapter)
5/16" allen wrench
teflon tape
thread sealer (usually a silicon based liquid)
Subaru plug for stock oil pressure sender: Part # 11024AA210
Subaru bottom washer for the Subaru oil plug: Part # 037018200
Your favourite oil pressure gauge sender hose (stainless steel): Omori part #
P-280 (or P-281, P-282, P-283, P-284; these hoses are longer in length)
1) Pull off the BOV hose. Then pull off the 3 other rubber hoses attached to the
intercooler.
2) Next use a 12mm wrench and remove the 2 bolts on the right and the left side
of the intercooler.
3) Use the 12mm wrench again to remove the 2 bolts on the BOV to remove the BOV.
Be sure to leave the BOV as is there.
4) Next, use a flat head screwdriver to loosen a clamp on the rubber hose from
the intercooler to the throttle body. There are 2 clamps there, just loosen the
clamp on the throttle body side. After that, loosen the clamp on the hose under
the intercooler, which is attached to the turbo outlet.
5) Your intercooler is now ready to be removed. Now wiggle it slowly and it will
come out. The hose connecting turbo outlet to the intercooler is tough. I found
it easier to stand next to the driver's side fender and wiggle/pull the
intercooler towards me.
8) With the intercooler off, now look for the oil sender plug (see pics below).
Use the 5/16" allen wrench to get the plug out. Now teflon tape all the threads
everywhere to prevent leaking. I first tightened my SS sender hose to the Subaru
plug before installing them onto the engine block.
9) At this point, I put the bottom washer on the plug and applied thread sealer
to the plug. Then I screwed the plug onto the engine block. Since it was
difficult to reach by hand, I just turned the SS hose to tighten the plug on the
engine and that worked fine. When I can't turn it by hand anymore, I used the
17mm crow's foot wrench to tighten the plug. (sorry, no torque spec here...)
10) once that's done, reinstall the intercooler by wiggling the bottom hose onto
the turbo first, then the hose on the throttle body. The wiggling may take a
little while. The rest of the screw tightening will be easy.
11) Lastly, connect your SS sender hose to your sender and you're all set!

My oil pressure readings
on start/idle: ~100psi
driving: 90 - 100 psi
warm engine, idle: 35 - 45 psi
The Subaru oil
plug is 1/8 BSPT. My SS hose from Omori was 1/8 BSPT 27 thread, according to
Omori, and it fit fine. However, the out-of-the-box SS hose was 0.5 meters long.
It is not long enough (doesn't give enough slack from where I mounted the oil
pressure sender). I have about 1.5 inch slack of movement available for the
hose... (luckily I ordered a second one just in case
)
Anyhow, if you do not have a oil sender hose, you need one. If your oil pressure
gauge is mechanical, get a LONG SS hose (like 2 meters long) or exchange for an
electrical one...
edit: corrected my mistaken Omori hose connector thread info from NPT to BSPT,
after calling Omori to confirm. My apologies.
part numbers:
Omori nipple connector (btw Subaru oil galley plug and Omori hose): P-185
Omori SS oil pressure hose (0.5m and comes with P-185): P-280
