35r on 7 bolt block, 6 bolt head, coolant plumbing

The_EE · 08-01-2008, 07:55 PM

Ok, I had three areas I could put this in, didnt know which one for sure so I picked this one as its what the problem is for.

Running in to a couple issues and wondering what you think can be done about this.

Situation is, I am currently trying to figure out how the hell I am going to plumb all the piping for the new turbo. The 2g water pipe had fittings capable of working with this setup no problem, the 1g seems to have some issues.

1g water pipe has a J shaped fitting that comes off the bottom.

2g block has a water fitting that comes off the block.

If I use both fittings, the one off the 1g pipe and the one off the block, there is no way to bolt the water pipe up to the block as seen in this picture.

So, I really only have one choice, which is block off the passage, like I did since my 20g is only oil cooled and run the water feed line to the turbo from the bottom of the water pipe. This leaves me with a problem. Where to return the water to the system?

Now, since I am running a 1g water neck, I have an extra bung available to use to return piping to the system, I am wondering which way I can go.

Two situations are.

Leave my coolant temp sensor where it is or move it to the higher location.

Nice new looking connector is my coolant temp sensor at the bottom, at the top is some sensor, dont know what but that is how I got the pipe. I am assuming it was a coolant sensor for the 1g. So I was thinking, running the other water line from the back side of the turbo to one of these using a brass barbed fitting, solving my problem.

So, can someone give me an idea if this will work out?

Problem is, what size is the fitting? I picked up a 3/8th barbed fitting and its not really wanting to go in all that easy and I am not all about forcing it in there if I dont have to. I did have a spare 3/8th compressor fitting with a flare end which goes in just fine but its a little loose.

Turbo should be here early next week and I kinda need to figure this out but with the 100* temps and 90% humidity, being outside in the sun is unbearable to say the least heh.

Oddly enough, MrPeepers called me one day asking me about those water lines when he and a friend were installing a 35r. I don't remember how he fixed it, but try PM'ing him to get his input.

Thank you, I will do that.

You actually feed the turbo using high pressure at the waterneck, and return it into your water pipe "loop".

I would recommend removing the loop, and having a 1/4" OD barbed fitting with 3/8NPT threads put in place, weld it, and then powdercoat to make SURE there are no leaks. Then just use 1/4" ID coolant hose to feed / return the coolant to / from the turbo.

Where is the coolant line circled going, that's where I have my turbo feed.

That line goes to the metal line that runs down to the oil filter housing.

I have a 3/8ths barbed fitting but it doesnt want to fit into the hole and I really dont want to force it in there and damage the threads on the water housing. I took the top half of the housing off and am going to take that down to the hardware store and see if I can find something that fits a little better.

Loop your coolant lines going to the oil filter, and run the feed to the turbo from there. Get an external oil cooler.

Couldn't you go from the waterneck to the turbo then out the turbo to the oil filter housing?

I would take that unused sensor out and put in a 3/8-3/8 barbed fitting in (it'll fit, just screw the bitch in with some teflon) and use that as the water feed line. Then eliminate the banjo bolt from the block. Then have the return go back into the water pipe since that is the OEM way anyway.

Here are some pics that I took tonight of my HTA's plumbing:

I used the spark plug wire socks to insulate the coolant hose from the turbine (since they run so close).

I got everything all hooked up. Only problems I had was a little leak from the block fed plug, which was a bitch to solve with the turbo in the car, I had to put some JB Weld on there let it dry, fire up the car, warm her up and wait for leaks. I had to go 3 times with JB Weld before I could get it done but its done. Its such a tight fit hehe.

Also, the barb fitting I got worked fine but it leaked as well so a little JB solved that. Then, my radiator started to leak. I was running a 1g radiator because it keeps the upper hose away from my manifold, it started leaking at the O ring for the automatic lines ( was only 1g radiator I could find ) so I went ahead and purchased an aluminum one. ) All is good now.

This setup is very similar to how I have my GT40R setup. Same situation, except I used a 1G non-turbo water pipe to remove the extra fitting, and then took a feed line off the lower thermostat assembly -- I think it was like a 3/8 NPT (drilled to fit, then welded in) to -6AN - 45-degree fitting with a -6AN braided line to a banjo fitting on the turbo (inner side between the block and the turbo), and then installed a modified lower radiator hose using a 2G lower radiator hose cut in the middle, and I installed an aluminum coolant temperature sensor adaptor drilled to accomodate a 3/8 NPT to -6AN fitting and welded that one in also, then ran a -6AN line to a banjo bolt setup to the turbo (outer side between the radiator and the turbo).

This is an option, but it is up to you how you want to run it.

Here is an example picture (NOT MY CAR) of the coolant temperature sensor adaptor (Pulled from RRE's website) that I drilled out and installed the 3/8 NPT fitting that was then welded in:
