2G Turbo Coolant Feed and Return

[sypherzero]

I guess this is really a two part question, and this pertains to the OEM T-25. I do not have any of the stock turbo coolant parts, so I picked up a set of Kinugawa coolant fed/return fittings. So the first question is, can I feed the turbo as I have it labeled in this picture of a 2g water pipe from JNZ, or do I have it backwards. Or completely wrong?

If the above feed/return will work, I need to block off the factory return on the block. Is there an OEM part that will block this off, or something similar that will work?

Also, I'm using an Evo III OFH with an external air-cooled oil cooler.

I personaly think stock coolant feed/return line for stock t25 turbo will be better, because fit as you mentioned one will not has enough lengh.
You will need a custom make connection hose to coolant pipe.
If you want to eliminate the stock oil cooler, just use a custom hose to connection both side instead of stock oil cooler feed/out. No need to block it.

Here bro! Using the diagram you can see what needs to be blocked off. I would run the oem feed and return for the turbo, or make your own setup work. Then you will need to have the feed for the ofh on the water pipe welded shut. Doing the same with the return which looks to go to the thermo housing. Or you could somehow loop it around with longer hose. I would do the permenant fix, which actually I'm doing to my gvr4 right now too! I'll be welding what I can and using a 90 ofh and nice ext cooler.

The port on the block in a 2G is the FEED for the turbo. Everything RETURNS to the water pipe. The feed and return cannot be the same source.

I would have the feed to the turbo from the pipe and return to t-stat housing. Like said above, can't have feed and return from the same pipe.

Based on how you've stated this, it wouldn't work as there's higher pressure at the thermostat housing than at any point in the water pipe. Feed from the thermostat housing and return to the water pipe and you're in business. Unfortunately for 2G owners like the OP, that will likely require buying more parts to create a solution.

You're right, feed from t-stat and return to pipe. Keep mixing up the flow direction.
