I have just put a turbo on my TD42 but mine is a GU.
I have pictures and all but I don't know if they're any goo to you if your block is different to mine?

Yeah the block is different as i have all genuine GU oil and water lines wish they were the same but

Ah bummer.
The oil feed you could always take from the oil pressure sender via t-piece. I got a hose made up at pirtek, they have the t-piece too. Cost me $40.
That's what I did with mine as I couldn't get the "proper" oil feed bung out of the block.

Oil return will be easiest to put straight into the sump. Your local mechanic should be able to weld a fatting onto the sump within minutes.
You gotta take the sump off though..... not hard just get a new gasket.

Water you just use a t-piece from where the heater hose comes out of the thermostat housing.

For the water return I used the bung in the block on the passenger side all the way at the back. Maybe I'll post some pics anyway, might help a little.

Here some pics, but I'm sure someone will have some more info on GQs.

But it might help anyway:

Water return-line (near the dump pipe with 90deg fitting)

Water feed (t-piece in the foreground, at the thermostat housing)
Also you can see the oil feed line that goes across over the rocker cover.

Oil feed at the pressure sender

These are the oil-feed bungs I was supposed to use but I couldn't get neither of them out

can the oil return go into a bung near/below the alt into the block? ???

found this but i still cant answer my own question

turbo oil only http://www.dencodiesel.com/pdf/Fitting/ ... 20TD42.pdf

water cooled turbo http://www.dencodiesel.com/pdf/Fitting/ ... COOLED.pdf

With doing my turbo conversion, I am looking at putting a 't' piece in the oil feed line to the alternator driven vac pump and using that for oil feed, and just draining the oil back to the sump.

And I was just going to block off the water feed to the turbo, I have been reading the info on a kit that use garrett turbos and it said water cooling was not needed due to the cooler temps that diesel run at compared to petrol.

You can tap it out of the alternator, pretty much anywhere with good oil pressure.

Its not a great idea to tap it back into the alternator return though, as both of them trying to drain into that can cause hot spots, and back pressure on the turbo and makes it a bit smokey.

yeh think i will take my sump off now and take it down to get a piece welded/brased on for the oil return.

DTS turbo kits use the same setup for water as the above pics, oil is picked up from the bung between the passenger engine mount and is drained back to the sump,

so GQ and GU is the same,

The oil return should go into the sump if you use a low mount turbo setup as the alternator drain is not low enough to gravity feed properly AFAIK.

Easy enough to get a bit of pipe welded onto the sump and you know it will be the best sulution.

As for water cooling, why not use it if you can? If your cooling system is up to scratch it shouldn't bother it.
The water lines are the easiest anyway as you can see from my pics.

Thanks for all the info and photos all underway so far so good next step is to mount a standard gu intercooler onto the gq could be fun,, any info on that floating around??

cheers josh

I'm going to intercool mine too but I won't bother with the standard intercooler.... too much piping.

I will get the intercooler from oondy (Big O 4x4 I think) it's listed on ebay and cost $800 delivered incl. bonet scoop and fan/thermo switch etc..

And it's designed to drop straight onto the intake so no awkward piping.

I think you will only need an adapter to fit a silicon hose onto your GU factory turbo outlet.

Look into that mate
