2G Evo 7 Bolt Oil Filter Housing

[Blurred Talon]

I bought an Evo 7 bolt Oil Filter housing from Mach V.
External Oil Cooler Filter Mount

I want to build an oil cooler set up but I'm not sure what what size fittings to order. I had some 3/8" NPT fittings and those don't seem to fit. I also want to add a 1/8" npt sensor.

Any help?

Its a metric fitting. You will need an adapter. Or you could go with AN fittings, mach V sells the adapter for that

If you're going with 8AN lines (pushlock, SS, doesn't matter), which you should as stock is a waste of time, you will need to get mm16x1.5 to (your choice size) AN. I went with 8AN as its bigger than stock. If you can pick up a stock cooler for cheap, they are a good route to go, and also use the mm16x1.5 to (your choice size)AN. I am glad i went with pushlock, i would suggest it to anyone.

Pushloc ALL THE WAY!!

Good thing one of these came up.

You will need a 16x1.5mm to a -8AN fitting. Get some fittings, lines, and an oil cooler and you are pretty much set hardware wise. Other then that it's just an oil filter housing gasket and bolts.

You will also have to open up and tap a hole on the bottom of it for the oil pressure dummy light. And depending on how you are feeding your turbo oil, the red arrow in my attached picture will need to be pulled and then used as an oil supply hole. It's either that one or the one just above it.

I just got one of these through a trade, and have a question. From my reading, we will also need 2 shorter oil filter housing bolts. Does anyone know the size and length of said bolts?

 

[Blurred Talon]

So I have to drill and tap a hole for the dummy light? What size is that tap?

I'm still not sure where to mount my aftermarket oil pressure sender.

 

[BoostFrenzy]

It's a 1/8th BSP thread I believe. Going to be hard to find one of those taps locally though. You'll probably need to order it online if a local shop that you use doesn't have one.

The sensor can be mounted by the red arrow. I found out that the other fitting above it has clean oil going through it so that is where you should mount your turbo oil supply line. And if you don't already have one, I recommend one of these Jays Racing Oil Pressure Sender Kits to mount the sensor remotely so it doesn't get messed up from engine vibration. It'll come with both fittings for a straight 1/8th fitting or a 3/8th fitting (like that of which the gold looking plugs are).

I was looking those up on JNZ, and the first two are showing up as "BOLT,THROTTLE BOD" is that correct???

 

[turbosax2]

Ya, it's normal for parts to be used in various applications.

 

[BoostFrenzy]

Sweet! Thanks Eric. Just making sure you didn't hit a wrong key. Now it's time to see what other goodies I'd like to pick up from JNZ .

 

[Blurred Talon]

Thanks for the part numbers.
So that upper plug should be used for the oil supply line?

Looks like the bolts are the same too.

 

[BoostFrenzy]

So that upper plug should be used for the oil supply line?

Yes. After looking it over, that is where clean oil flows through. The other one can be used for a sensor if you'd like.

I am taking a wild guess at this, but the new bolts will go in depending on height of the OFH correct? The "top" two have the same depth, and and bottom two one needs to be deeper then the other. So they go in their corresponding holes depending on depth and length of the bolt no?

Yea, looks like one would use a longer bolt.
What is the thread size on the stock oil pressure dummy light?

 

[turbosax2]

What is the thread size on the stock oil pressure dummy light?

1/8" BSPT.

 

[Blurred Talon]

1/8" 28?
McMaster Carr part number 8328A11

 

[turbosax2]

Yup, that tap looks like the right one.

 

[Blurred Talon]

Awesome thanks. Hopefully my Millwright friend has one.

Also could I use this oil cooler kit sold by STM? STM OIL COOLER KIT | 90-99 DSM

 

[turbosax2]

Sure, just make sure to choose the 7 bolt option obviously.

 

[Blurred Talon]

Awesome. Saves me money over building one myself.

Can I also use the 16x1.5mm for my oil feed port?
Also I want to use a small oil filter on my feed line, good idea/bad idea?

 

[BoostFrenzy]

Just a quick question for you guys that have either a 90 or a Evo OFH. I just got in my fittings and washers from MachV to go to a -8AN line. I got 4 of the OEM crush washers with the rubber ring, do I install just 1 or 2 per fitting? Because their site says you need 2 packs (total 8) if you are going to use banjo bolts. So my thinking is 2 per fitting right?

 

[BoostFrenzy]

Can I also use the 16x1.5mm for my oil feed port?

I don't think that's possible for the oil feed port. The 16x1.5mm are for the lines going to and from the oil cooler. The feed line holes should be 3/8th BSP.

Do I have to replace the OFH bolts when doing this or can I use my factory stuff? Looking at doing this over the weekend finally.
