Turbo water line hook-up?

[spyderdrifter]

I know this has been beaten to death; many, many, many times.... , but there's one thing I've never seen resolved yet. I got a 6 bolt w/ 7 bolt head. Getting a 16g in a few weeks once my tax money comes in.

I got all the right parts for the swap, but need to know if any of you out there have resolved the issue of hooking up the water lines to the turbo. I don't want to 'T' the feed and return lines together because I think it just defeats the purpose of being water cooled. With the lines being 'T'd together, the water is basically just spinning around without being cycled back to the main water flow. It's not getting a chance to properly remove heat from the turbo. I see this as though the turbo is attempted to be cooled off with already hot water, it's retarded.

I plan to use the 1g t-stat housing hook-up as my feed source, but don't know where to go for the return line. The main water pipe I have to run to the water pump has a threaded bung on the underside near where the pipe branches off to run to the intake manifold. It's plugged, but I do have a water line for this location. Is this the best way to have these 2 lines seperated? If not, how else would be a better option?

The use of a "T" typically means there is a third leg going somewhere. I assume you mean people loop the feed and the return which is only done if the turbo is to run coolant-free.

The original system is fed from the thermostat housing and returned to the water pipe. The threaded bung is the original return location for a 1G. Pretty cut and dry.

Yeah, I did mean the looped part. I hate that setup. I've never owned a 1g or have had the opportunity to look at one that hasn't been disassembled already. I've looked through pictures of 1g engine bays and haven't gotten to see anything from the right angle either. My last eclipse had a 6 bolt swap, but it had the looped water line setup, but no bung on the bottom of the pipe. This is my first time actively doing the entire swap myself and I want it done right. I will link the return to the bung as you mentioned.


One other similar issue. For the water lines involved with cooling the OFH, I see what to do for the line coming off the main water pipe going to the OFH, but what about the other line coming from the OFH? Where does that one go? I got another hard line that might be long enough to T it to the t-stat housing, but haven't tried yet. Is that the right way to hook that up as well?

The thermostat housing will have two nipples coming off the front, one to feed the turbo and one to feed the oil cooler. A hard pipe (see pic below) is connected to the thermostat housing by a hose, snakes behind the turbo, and down to the oil cooler.

Thanks for the link, and pictures. I guess I do have everything I need. Just wasn't sure since I got parts from several DSMs and wasn't too sure on some of the routing. Thanks for the help.
