OEM Filter block and Coolant lines to manifold

[Master Chief]

Hi all.
I have an european market S14, SR20DET.

I am going to replace the OEM oil filter block, on the S14 SR20DET, with the TOMEI N2 oil block, and a remote filter relocation and oil cooler.

My problem is that on my engine, the OEM oil filter block incorporates a built in water cooled oil cooler.
Canceling the oil filter block, means i am left with some open coolant pipes.
One on the block, and one on the pipe that goes to the heater, under the manifold - see the pictures.

I know that on some other markets, the OEM oil cooler is none existent.
That means that the nipple in the block, is blocked, and allso the pictured pipes, look different.

I already blocked the nipple in the block, and i want to cancel the hoses marked with a RED X !
If i block the pipes marked in GREEN in the pictures - will i be ok ?



Another thing, is that on my lower intake manifold, at the back, there are 2 coolant nipples. I am not sure what this is for, but it seems to be runing coolant thru the pipe connecting the number 2/3/4 runners.
See the picture.
I know that on other markets, and newer SR20DET's, the manifold, looks different and is without those pipes.
Can i cancel these pipes as well ?

My main concern here is as the runner number 1 has the coolant pipe from the head, and i was thinking the passage conecting number 2/3/4 and runing coolant thru them, would be to equalize the temps to the number 1 runner.
The fact is thoug, that as i said. Other market Sr20DET's, dont have this.

Not sure what to do.

I would like to confirm all of the above.
If somone has pictures of there above items, actualy looking different than mine, this will help a lot.

Does anyone have a picture of the Hoses under there manifold, or of the metal pipes i pictured - on an engine that doesnt have my manifold type/oil cooler ?


Any info on this will be great.

Thanks,
Dany.

The easiest way to get rid of the stock oil cooler is to loop hose from the cooler inlet right back to the outlet. But if you want to be more thorough you can remove those extra hose. If you want to see how, the S14 Service Manual that most ppl have (search) is actually Euro version. You can compare the hose routing in LC section to the S15 service manual, which do not have this oem cooler. Hard to explain but you can see in the manual.
You can also get rid of those coolant lines to the oem lower manifold. The japanese ones dont have those, see my pictures.

I did compare the S14 manual to the S15 - and although the S15 manual does not refer to the OIL COOLER itself, the pictures of the above Metal Pipes, are identical to the ones in the s14 Manual.

In fact there are many instances of the pics beeing the same, even though the parts are a bit different.

Iteresting about the Japs not having those.
I would die to see the Metal Pipes i have pictured, of the Japaneese version.

I Wonder why the Euro version, does have these....

Thanks.

The green marked nipples can be capped off without issue. Or what I would do is cut them flush then weld it up, looks a lot cleaner and you're certain to not have leaks. Caps can deteriorate over time. As far as the manifold, I'm not sure about that.

I dont have pics of those pipes but you can see from the back of my engine.
Those are quite simple and goes straight to the front.

I would not be too worried about not running the coolant through intake manifold. It seems that they use it on Euro to help with cold start by letting the intake warms up faster.

Great , Thanks !
