Omori Gauge Installation Question Galore

CobraKLR · 10-05-2003, 09:15 PM

I need a little help installing some used Omori gauges that I recently bought. I have the electrical portion done and need help with the sensors. I did a search and was unable to find answers to my questions.

First off,
My Oil Pressure Gauge came with a T and a brass coupler. I am assuming that this installs in the same place as the stock oil pressure sensor. Unfortunately I do not know where that is. Any help (especially pics) would be greatly appriciated.

Second,
I need an adapter to install the included EGT Pyrometer Probe in my Vishnu Uppipe (I am putting it here as I am thinking about going with headers soon and don't want to have to get an adapter welded twice). Does anyone know where I can get this adapter (not sure if the included probe is 1/8PT or NPT or other), the Vishnu bung is the same as stock.

Third,
My oil temperature gauge did not come with a oil temperature sensor. Omori-NA's web site says they can't get product and just have an automated response to emails. Does anyone know where I can get one of these? Is it possible to use the stock oil temp sensor?

Thanks in advance.

I can only address your third question, I'll leave the others for those with knowledge of those items.
There is no stock oil temp sensor unless you have the optional gauge package, do you? If you do it's unlikely the existing temp probe will be compatible with the new gauge, you may get some readings but it won't be accurate. You may want to contact an Omori dealer such as J-Spec Tuning and see if they have a sensor available.

CobraKLR · 10-05-2003, 09:29 PM

Thanks mulder, I sent J-spec an email request for the part - hopefully they have a source. I don't have the stock gauge pod, so I guess that option is out altogether.

Anyone else on the other questions?

Kean · 10-06-2003, 05:24 PM

I think I can help you on the first part. There's a plug under the front of the intercooler that you can tap into. Check this link out to get an idea of what I'm talking about:

.....you'll need an "Oil Galley Plug" to replace the "blank" that you take out. You will thread the adapter (that connects to the stainless steel, braided line) into this. Check out this thread to see a pic of the plug you need to buy:

http://forums.nasioc.com/forums/show...il+galley+plug

The tutorial on Scooby Mods tells you that you'll need to remove the intercooler to perform this install. Although it will make it much easier, I'm telling you that it is possible to do it without removing it (small hands and patience help).

I have the Omori 52mm Oil Pressure gauge.

Hope this helps a bit.

Omori-NA is defunct, your best bet is J-Spec or Gruppe-S. Both should be able to get oil temp sensors.

I don't know if there is an adapter for the EGT bung, but you are better off placing the EGT in the exhaust manifold very close to the exhaust ports. That will give you a much truer reading on the EGT gauge.

CobraKLR - Hi, I think it was you that we had responded to. We do have the oil temp sensor. Additionally, we have the 1/8 PT to 1/8 NPT adaptor. That piece is right on our site and can be ordered directly.

If you have any q's just let us know.
Thanks,
Thaison

CobraKLR · 10-07-2003, 02:58 PM

Thanks everyone for the responses.

Kean, the pics will be invaluable.
MCA - I am putting it in the uppipe for now until I do headers as I don't want to go through the trouble of a manifold bung weld/tap for a temporary setup.

Thiason,
I got your email - thanks, I will be purchasing soon. As for the EGT adapter is that the one needed to plug into the stock sized bung? There is a screw labeled M18 in my extra bung, which is the same size.

Thanks again everyone.

J-Spec Tuning · 10-08-2003, 01:25 AM

CobraKLR - The 1/8 PT to 1/8NPT adaptor will fit into a 1/8NPT bung. The stock sized bung is different. We have a fitting that allow you to fit the EGT probe into the stock EGT bung BUT, clearance is a huge issue. With the extra fitting + the Omori EGT bung + the EGT probe, the whole piece juts out too far from the uppipe and interferes with a engine component - forgot what that piece is but I know it just does fit due to clearance.

The adaptor is really meant for the EGT probe to be inserted into a 1/8 NPT bung.

Call us if this makes no sense.
Thanks,
Thaison

CobraKLR · 10-08-2003, 01:32 AM

Thiason,
I'm actually not looking to locate it in the stock location. I have a Vishnu 321 uppipe that has a bung that points more downward towards the front passenger side axle. How large is the adapter in question? I think there is sufficient clearance there, but I would like to measure and make sure.

Thanks

STI 2 NV · 10-08-2003, 09:43 AM

where on the site is the 1/8 PT to 1/8NPT adaptor?

CobraKLR · 10-08-2003, 10:58 AM

STI2NV, it is on this page http://www.j-spectuning.com/omori_yg.htm , left column, last item.

STI 2 NV · 10-08-2003, 11:06 AM

thanks man. so i will need this to do the egt install? is there already a precut hole? sorry for the questions, but i've never done a gauge install before besides boost and i'm just not sure what to do. will any drilling be required?

CobraKLR · 10-08-2003, 11:10 AM

To install an egt probe you have to have a bung welded and properly tapped to part of your exhaust (most use the passenger side exhaust manifold). As I am going with headers in the future I am looking for a solution to use the extra bung already in my Vishnu Uppipe so I don't have to go through the weld/tap exercise twice - this adapter is not the one needed to do that, still looking for the one that is.

STI 2 NV · 10-08-2003, 12:13 PM

i guess i'm just not understanding. what exactly do i need to do to get this egt gauge installed? what will i need? where does the probe go? is there already a spot to put it or will i need to drill? i'm pretty lost here...obviously.

CobraKLR · 10-08-2003, 12:59 PM

The most common installation is to remove the passenger side exhaust manifold (the cast iron piece that connects to the uppipe). You will have to have a bung welded to the manifold (generally where the 2 exhaust ports meet). You will then have to have the bung that was just welded drilled and threaded to fit your probe threads.

mca · 10-08-2003, 02:42 PM

No need to weld in a bung for the stock exhaust manifold. Just drill and tap for the EGT fitting that is supplied with your gauge.

STI 2 NV · 10-08-2003, 03:49 PM

how easy it is to remove the exhaust manifold?

CobraKLR · 10-08-2003, 05:07 PM

Not bad. Jack up the front of the car, remove the black plastic splash guard. Unbolt the cross-pipe, and the uppipe from the manifold. Unbolt the manifold from the engine block and remove it. You may need some new exhaust gaskets to prevent exhaust leaks on reinstall.

doesn't sound too bad. so i just remove that and drill a hole for the supplied adaptor and then tap the hole?

CobraKLR · 10-08-2003, 06:43 PM

Whoops, I forgot the front O2 sensor needs to be removed as well. Not too bad if you have the right tools. It is accessed through an access panel in the passengers side wheel well.

O2 sensor needs to be moved where?

CobraKLR · 10-09-2003, 11:17 AM

No it needs to be removed to get the manifold off.

STI 2 NV · 10-09-2003, 01:20 PM

gotcha. are the instructions omori provided any good? if not would u be willing to write up some nice instructions for me...if u get a free moment? thanks so much. ~nick

CobraKLR · 10-09-2003, 01:30 PM

I bought my gauges used and they did not come with instructions. I used the instructions on omori-na's web site for the wiring (very straight foreward). I haven't hooked up any of my probes/sensors yet.
