Water Cooling Routing - Am I doing this right?
 

Evening, have my turbo etc all in place, only thing left is to get the water cooling into place before I get it back into the car and then the fiddlyier stuff, heat wrapping etc.

From what I have gathered and figured out.
1 goes back to the radiator.

2 is my water output for the turbo, so will go to connection number 4

And for the water feed.. do I just Tee off from 5 and straight into number 3 (water inlet on the turbo) Or do i have to right angle off number 5, i.e. block it off from the connection on the mixing manifold and go straight to the turbo?

As much simple advise would be great, First time build so want to make sure im doing it as right as possible...
Thanks

ebay manifold detected

this doesnt help at all

The manifold isn't helping indeed.

You go from 5 to 3 and 2 to 'output'. 4 is for the heater, don't touch. Same for 1, which is the lower rad hose.

4 is for the heater?

I can't recall ever seeing that before. I know the big slip on pipe above the one circled goes to the heater.

Yeah I made a dumb and assumed the 4 was for the heater tube, not the actual circled nipple below. Never mind.

4 is not the heater. the pipe right above it is for the heater. he's using something weird like a fwd bp mixing manifold or something like that. you could probably use it the way you outlined, but most of us don't have 4 where you have it so we just loop 2 and 3 into 5 instead of tee'ing off it

and yes your manifold is fail aidz and gay

Water enters the turbo on the bottom and exits the top.

There is one thing in our system that makes water flow . . . the water pump. The lowest relative pressure is at the WP inlet. The highest at the water pump outlet. Everything else is relative and falls in between these two (depending upon the restrictions they've gone past).

The inlet of the water pump is what we discharge into for water flow since it is reliably the lowest pressure. Try to get all of your auxiliary water circuits to terminate there. That is why the mixing manifold has so many ports. For your purposes, you can consider ports 1, 4 and 5 to all have the same, low pressure. These are all inlet ports to the water pump.

What you've drawn definitely will not work because 4 and 5 are essentially the same point. You need to source your water somewhere else and then route it into the WP at 4 or 5.
