turbo water feed

[5UBZRO]

I am currently running oil feed and return hoses to my new turbo and noticed the turbo isnt water cooled. what do i do with water feed pipe coming out of the head? do i just blank it off or do i have to loop it back into the header tank?

You could do either, i would loop it back to the header tank myself.

Im going to get a custom header tank made and if i can get away without having to run another hose i will. just wondering if anyone has come across this before...

Earlier on this site there was a discussion regarding the water pipes found on OE Subaru Turbo setups.

Basically the water pipes are there for Turbo Longevity (if shut off hot, coolant will circulate to cool as the engine oil will not)

Not sure if that answers your question.

Why's that? Many good turbos arn't water cooled, I wouldn't take the water cooling away from a garrett gt turbo though Mmmm plastic bearing cages. I don't know what the vf ones are like but i'm sure Murch would know.

All oil only turbos need is a little cool down time befor switching off to get the heat down so the oil dosn't turn to custard in them when switched off.

As said you can either blank or loop the coolant feed, it makes no difference as the coolant flows to and from the same place anyway. If you're making a new header tank then just omit that inlet.

Vf turbos have plastic bearing cages as well, although Steve Murch does an up grade to a bronze cage. I like ronin's idea of having a seprate turbo water cooling system set up, stops all that hot water getting fed back into the heads.

acutally water goes from the heads to the turbo, then to the header tank, so not such an issue

Hmmm lets see, i would run the turbo water cooled if i could. But its a brand new master-power t-70 which isn't water cooled so that puts paid to that. And i have beefed up the oil cooling considerably, so fingers crossed i won't have any trouble with cooling there. the reason i asked that question is i remember someone asking on here a while ago about blanking of the heater hoses as they wern't going to run a heater and someones reply was that you had to bridge or loop it rather than blocking it off. all i was concerned about was wether the same applied to the turbo cooling side of things.

Heater core hose's must be looped if removed

Turbo cooling hose's just join together is easiest, ie out of head to surge tank all good

All good with decent oil cooled turbo, I miss read your post thinking you where removing the water cooling, My bad

haha all good. it was a bit misleading now i read it. all blocked off now. amazing how much useful info i have gathered off here. Now while on the subject of cooling, there are two pipes that come off the water pump and run up the front of the motor. One plumbs into a heater hose, where does the other go? onto the bottom of the header tank? its been 18months since i pulled the motor out and the memory is a bit scratchy haha.

yeah bottom of the header tank, they are both feeds to the hot side of the thermostat
