I'm really confused where to plumb the water lines for my turbo..
where do people tend to take these from?!

the email I had when I asked the guys who provided my turbo kit where the lines were intended to be taken from said..

'The water lines are our standard lengths to go to the upper water neck and rear water pipe'

I asked him to clarify and got..

'Upper water neck is the aluminum outlet where the upper radeiator hose exxits the head. The rear water pipe is the pipe the connects the water pump to the thermo housing across the back of the block.

It's still not that clear to me where he intends to take it from :wtf:

Can anyone explain it better/show me on a picture what he means?
or explain somewhere else thats a good place to take them from?

Thankyou :)
 
By the sounds of it quite simply t into the top hose and t in to the metal pipe that runs across the back of the block above the oil filter
 
I have seen people use the block coolant drain plug as a return, and used one of the radiator hoses as a feed.

Me, i never run water lines in the 6 odd years my car was boosted. Turbo is still sweet
 
Which cylinder head are you using Nicole? I'm running my feed from my top water hose housing. Just a simple -10 AN 90 degree fitting and return to the block drain plug. This is on B18C4
As you can see simple and reliable with no leaks. You going to have to tap into the housing. I would get an engineering firm to do this for you once you have your fitting.

Seems like more work to run them than it's worth, not sure how the water temps will react trying to cool a turbo, less heat in the oil though?

Yeah that's what I think, the cooling system already has a lot more work to do, rather than try to cool 800 degree water from a turbo.
 
I'd agree with just run oil lines forget water lines the difference in lifespan of a turbo is seriously minute compared to the extra heat it has to deal with don't forget a big oil cooler that's important :)
 
It's a brand new expensive turbo though and if garrett recommend this, I kinda wanna stick with that.
I've also read the oils restricted so it might not cool as efficiently...
Also I'm guessing it'll keep the heat down a little to the oil, keeping internals cooler?
@irf is the drain back the blank in the front of the block?
The kit came with a weld on fitting for one bit which I'm guessing is that water housing for top hose

That's the one, Pretty sure it's either a 17mm or 19mm. I tapped into this bolt using supplied -8 fitting. When removing and replacing the bolt be careful not to strip the thread as it's mega fine.
 
Definitely use it as Garrrett intended, they didn't put it there for the fun of it.

Is the water feeds not used in more OEM applications. To try and save the turbo from over heating the oil when Joe Bloggs just switches his or her car off after a thrash?
 
For me it's more the oem applications water cooling system is designed to work with the turbo.
Our little half rads I think may struggle on track if given the extra job of turbo cooling aswell.
Full width rad would sort it but her manifold won't allow that, unless custom I suppose.

Wastegate might be in the way, If she's using ramhorn.
 
Go auto works mini ram, wastegate is in the way, this is what im trying to say lol
 
The amount of heat put into the cooling system by the turbo will be negligible.
 
Sound confident enough for me!
Suppose we'll find out eventually
 
Makes sense, the water is only really to cool the bearings in their BB models after shutdown and does very little during normal use. Learn something new every day!
 
hi nicole

i run my water lines from my IACV to the turbo and then from the turbo to the little 90 degree pipe on the coolant return on my B18C4 Block.
