Small 16G turbo coolant feed

[usmc0651dns]

So after careful consideration, I have decided to use the coolant lines for my small 16G install. Since my wife (Murphy's law advocate) will be driving the GSX from time to time, I don't want to risk anything. So here is my question. I bought the car with a 18G installed and omitted coolant lines. I found where I think the feed line previously connected to the head. Is this it, and what or how do I go about setting it back up? Thanks.

Disregard the "X"d out circle. It's been a long day.

What you circled is the bolt holding the thermostat on. Match the colors below in the pic.

The other bolt you circled is where 1g's take their oil feed from. 2g's use the oil filter housing fitting.

Yup, that's the oil feed for the turbo. And for a 16g, I would definitely recommend that you use that feed location as apposed to the oil filter housing.

I've already set him up with the appropriate restriction to feed from the filter housing just as his 18G was. (The 16G came from me).

Ok, maybe I missed something. I know that the rear turbo coolant line attaches as shown above. I guess my question now is, where does the front line attach?

 

[TSITurbo95]

Look at the image above. The 2 red circles go together, and the 2 black go together.

 

[JusMX141]

That is correct...the front coolant line then attaches to the block just below the water pipe, behind the compressor cover. Since the old 18G did not have water provisions, this was probably capped off via a bolt threaded into the outlet.

I think I found the source but I am not sure. I have attached to pictures indicating what I think it may be. If it is, what do I need to set it back up again? Thank you once again.

 

[99gst_racer]

7-bolt block? If so, the other coolant port is right behind the compressor cover. From the factory, it was a banjo fitting and banjo bolt that threaded into the block.

 

[usmc0651dns]

No I believe it is a 6 bolt swap with 2G head. Does that make a difference?

 

[99gst_racer]

6-bolts attach the coolant line directly to the water pipe.

 

[usmc0651dns]

Which nipple would that be then? The one in my first set of pictures is already being used by the other turbo coolant line, from what was mentioned earlier.

I am using a 2G thermostat housing, by the way. No clue which variety of water pipe. Not really sure if that matters.

 

[99gst_racer]

Well, you have a 2G water pipe installed there, so I'm really not sure what you need to do. It's also been about 6 years since I've used coolant lines, so I'm a bit rusty on possible routing solutions.

The circled area in that last pic is just a plugged access hole used to drill an oil passage for the front balance shaft.

 

[usmc0651dns]

Hmmm. This is turning out to be a bit of a bother. So if I decide to omit the coolant lines after all, I can just leave the hard lines attached to the turbo without blocking them off, correct?

 

[JusMX141]

I vote to forget the coolant lines. The fact that you have no way to effectively tap into the block would be the deciding factor for me....especially considering your 18G had hardly any play, bearing wear, or oil coking despite having no coolant.

 

[usmc0651dns]

Justin, so all I need to do to omit the lines is to cap off the nipple on the water line shown above, correct? I don't need to do anything to the coolant hard lines on the turbo itself?

 

[99gst_racer]

That's correct. In fact, you can remove those hardlines from the turbo and leave open holes on the CHRA.

I've seen guys who put plugs in the holes on the center housing, but that's completely unnecessary. In fact, I'd rather not put plugs in the holes so air could pass through the coolant chamber.

 

[99gst_racer]

^^^ I completely agree.

 

[usmc0651dns]

That seems to be the best way to go since my water pipe and block don't have the correct outlets for the coolant setup. Thanks so much guys.

Old topic I do want to bring it up again really quick to get a confirmation.

Justin semi knows how my car was set up, with some big turbo, I picked up a TD05H.

I can just leave my coolant holes open on the turbo, instead of run them with coolant in it?
I'm wondering cause all my stuff for turbo coolant was already capped off, engine wise.

Also the bolt size for the oil feed for it? My old one doesn't fit in the least.
