Cooling setup for 4agte V-mount
Car - ke70
motor - 4agte
use - Cooling arrangement for header tank & turbo
problem - dont know how to run cooling to turbo/header tank
occurs/started when - when I put it together
Details:
Hey Guys,
I've cut my car up, installed V-mount for the rice and epic drifto, booked the car into get the ECU wired/tuned up next week and I need to get the cooling system sorted out before it goes in.
From all the googling I have done, it looks like most ppl run water to the turbo by tee 'ing off the heater lines. Not running a heater box so I'm hoping it is as easy as the diagram below.
What I don't know if the line from the turbo to the header tank will flow enough to cool the turbo and not too much to create too much pressure and bye bye turbo. Will it fill the header tank too fast and just spit it into the overflow bottle? Or simply if what I am thinking is just completely wrong and there is a way better way to do it?
Has anyone run a header tank on there 4agte and if so help please? Any advice would be great and photo's would be awesome too!

Diagram looks fine...
I'd try to mount the header tank higher than ther rest of the cooling system and then remove the cap from the radiator as its no longer needed because of the bleed pipe that runs up to the header..
Also make sure that the bleed pipe is mounted on the highest point of the radiator...
Yep thats cool, I should be mounting it on the strut tower as high up as it will go.
I'm not one that knows about fluid dynamics, but I guess that because there is only one pump in the system, and as long as I dont go from a small pipe to a big pipe (due to venturi affect and differential pressures?) the pressure should stay the same around the whole system. Therefore the header tank should not overflow???
Well that sound correct in my head, but I dont really know much?

The header tank is basically just a remote resivour. It needs to be fitted with a normal preasurized radiator cap and shouldn't overflow...
I don't think the pump would have anything to do with the preasure in the system.. it only moves the water.. The heat is what increases the preasure..
And that inturn will create some water movement through some of the external piping as the heat rises and the cold obviously falls..
I get it, just clicked; thanks Redwork.
It works just like the radiator, it wont overflow untill the pressure is greater than the rating of the radiator cap. I was over complicating it in my head, of course the header tank is pressurised
Anyone else think that there is a better way to do this, or have I got it pretty much right?
yes the header tank should have pressure and will just work like, the top and bottom tanks in a radiator, and when the pressure gets too high the in header tank the radiator cap will release it just like it would if you had it on the rad
also, Im running an ae92 remote thermostat and was thinking of running the the header tank return to the top inlet of the thermostat housing, as in the image?
That seems to be the return for the heater anyway, just wanna be 100%
