Water cooled Turbo

Turbo upgrade on the way, but as I have an early car, I now need to ADD water cooling for this new unit.
Anyone got a picture of where the water comes from for the cooling ......... and wher the hot water will go back to in the water circuit?
Many thanks in advance.

PS: searching for words like "water" "turbo" and "cooling" basically bring up every post on the forum. lol.

Hi Simon,
Doesn't the parts book show the differences?
Just a thought

There is a metal pipe that connects to the heads under the turbo ie joins the heads water circuit together .This has the connection for turbo water .Two styles of pipe,one with,one without .Feed comes from top main hose to waterpump,goes through the cover blower,the silly spiral heatsink leak valve,then hose to metal pipe into turbo .
You will need the later pipe between the heads or make up a silicon direct from the turbo to connect lower down where the pipe feeds into the oil filter cooler hoses .
You can see it here.

Hey Simon,

A nicer way of doing it would be to run -6an jic fittings in and out of the turbo using new hard line or braided hoses and joining them to the water pipes with simple weld on fittings. This will get rid of the horrible flexi pipe, rusty fittings etc.

Alternatively you don't need to run the water through the core, its there primarily to stop oil coking the bearings on daily driver/shopping cars. As long as you use high quality synthetic oils which get changed at regular intervals and don't turn off the engine after hard acceleration it will be perfectly fine. All the aircooled Porsches and VWs run watercooled turbos with no cooling, never had any issues.

Interesting ..........
The hybrid turbo that has catastrophically failed, has been on the car for at least 6 years.
It has a water cooled core ....but no water has been fed into it.

This is what I did, I broke the fitting on the metal pipe Clee posted the pic of, and although you can get the pipe from SimonAuto, the flexi which goes between it and the turbo was a different matter, so some re-engineering was called for.

Turbo water feed now comes from the front via a tee into one of the large hoses, I made up a braided hose back to the turbo, return pipe goes into the oil cooler.

I will have a look, see if I have pictures.
It works, but maybe pay extra to get the fittings in black, rather than the normal red or blue, unless that's your look of choice.....
