I have a sandwich tee off the front water neck on a D16Z6. It has two ports on it (with included plugs). Can I just loop it through the turbo and back to the T, or do I have to run the return elsewhere? TIA from a FI noob.

 

I have a -6 fitting welding to the water pump pipe behind my block for the feed, the front water neck i'm using for the return.

 

Nice. That sounds like a mighty fine idea. What kind of metal is the water pipe?

If anybody else has suggestions, I'd love to hear them. (Hoping to avoid welding, but certainly not out of the realm of possibility)

 

Have you thought about picking-up off the front freeze plug and returning to the radiator?

Effective, and cost-effective concerning fittings and lines as it's the shortest method possible IMO.

 

you think there is enough pressure in the block to force the coolant through the turbo and up to the upper rad hose?

seems like the water pipe is the best ticket.... but im open to options!@!

 

I use the line that used to go to the throttle body as the feed and the return line from the IACV as the return. No problems so far and no welding required. (bypassed the TB & IACV coolant flow)

that would be the proper way, the water is pumped from the water pump through block up through the head and out the upper hose into the radiator


the water pipe on the coolant tube in the back is return into the pump, you need to come off the positve flow side of the pump, block or head

damn nice looking hoses and routing

 

Just so the OP has a full idea on how everything comes together

 

We have a 4294R that uses M18x1.5 on the center housing and converted to a -8AN flare.

We used a 3/8" NPT to -8AN flare off of the VictorX manifold and a another M18x1.5 to -8AN flare adapter on the thermostat housing in place of the fan thermoswitch.

The fan thermoswitch got tossed because the fan relay is wired to constant on.

You can also do this and still retain a coolant temp threshold for fan activation if you have the S300 (or other standalone) and wire an output with conditional activation.

 

bumping this from last month. is everyone running the return to the top of the radiator? i think ive seen some people using the bottom as well. any advantage of where you weld the bung on the radiator?

bump. i know there are a bunch of gt-r turbos on this board

Thanks for the in depth pics...helped me out

 

I welded a Bung right at the bottom of my radiator for the return, total line length is less that 1'.

I'm thinking about doing this as well...seems like an easier route to take.

 

is there any difference between doing the return on the top or bottom of the radiator?

I'm pretty sure it just has to do w/ the length of the line you'll need. Other than that, I can't see there being any other difference.

 

Only thing i can see being on the bottom is the heat from the center cartridge will be transfered into the line going to the bottom of the rad and will not be cooled off and go back into the motor. But i dont think it s big deal. I would do it to the top if it was my car.

How much coolant do you think passes through a -6 line? I have heard some stuff a long time ago about GT Coolant Lines overheating cars but I sure as hell have not experienced it. I am running a 1/2 Radiator blocked by a huge Intercooler in 95+ Deg heat and I am not overheating.
