RB25DET NEO Turbo water return line

[shortyboy]

Im in the process of swapping out turbos for a Hypergear ATR43SS-2. I bought a water/oil line kit from Mamba, for Garret GT30, according to Tao. All fittings fit properly, except for the water return line. It has a -AN fitting to hose barb. From what I see, I need to remove hardline and install hose barb fitting to rubber line behind the head. I located the rubber line but is there an easier way to gain access without taking valve cover or intake manifold off?

Do you have a link to the kit you bought?

I don't have anything helpful to contribute other than suggesting to make sure that you do it right. It's a pain now, but it will be even more of a pain down the line if you have to fix it again. I've been ignoring a small leak on that return line fitting in my car. Still weighing up what to do with it.

Jonny @Dose Pipe Sutututu has routed it back to the front of the engine to make it less painful. See this and following comments in his build thread. Not sure how it has been holding up since though.

I've driven it around "in da hooodd" and it seems ok, have driven it around with the A/C on as well to generate more heat. So far no leaks.

Yet to do a long drive OR a track day in it, so both will be the tests.

I think if I were to do it again, I would just plumb the water return straight into the intake manifold's bleed ports (un-used) on the top side, noting that I have an aftermarket one.

I hope this works well, because I cannot be fked working on the car ever again  

 

In terms of your usual highflow kit, I would just return the water to the hardline behind the head.
