I don't understand your question....but I'll try to help......if the turbo has a position for water lines to be fitted it MUST have them fitted, It usualy means the differance between bearing and bushed turbo's, also the turbo's life will cut short , which may result in a worst case senario of a completly stuffed engine
have you ever removed the water lines from a factory turbo to see the pressure the coolant is moving at? minimal at best.
i asked the same question at the turbo shop i deal with and their answer "the cooling lines helps for shut down, if you use proper shut down technices then you do not need the water lines attached"
in other words, if you are an idiot then you need to run the lines but no matter what you do abuse will equal a dead turbo.
the idea of a stuffed turbo just because you do not use the water lines is misleading.
you can get bushing or bearing turbos with water jackets bossed in.

Hi crushers
the assembly of turbocharger has been made from turbo shop, therefore I have not taken apart the water lines.
what is " proper shut down technices "
I can send the pic to you,in order to insert it in the thread ?
Thank you.

Proper shut down technique is basically wait until your turbo is cool enough that it won't burn the oil in the lines and clog it up.
Just wait at idle for a few minutes after you've been running it hot and you should be fine. Some people even claim that diesels don't need to cool down at all because they are much cooler burning than gasoline engines.
Best way would probably have a pyro after the turbo to see if its cool enough to shut off.
true.
the reason for damaged to turbo/engine would be due to shutdown procedure. Shut down would be 5min for a fair trip 2mins for a trip down to the shops, I personaly would not go below a 5min shut down. the best way to solve an idiot proof shutdown would be to fit a turbo timer.
I deal with alot of idiots in my line of work and turbo failure would nearly always be due to driver error.
I plugged my water holes in my turbo.
I do not agree they are needed. Maybe for a gas engine it is a good thing. But on diesel I do not see the purpose. I also do not see the why the bearings VS bushings would matter if it had coolant or not.
5 mins idling for cooldown is a little excessive for Canadian temps. Oz is going to be a different animal for engine operation.
We do not know where in the world the original poster is from.

if you talk to the big boys, i;e 18 wheelers they'll tell ya if they are shutting the rig down they just let it idle for a couple mins while doing logbook or whatever, if you talk to the manufactures i;e CAT they'll tell you just let it spool down 30-45 seconds, this is to let the turbo slow before it loses oil pressure when you shut it down, they dont say anything about temps.
so what do ya do? when i shut mine down i just let it spool down, and thats only if i feel i have high EGT temps for one reason or another otherwise i drive it like a regular gasser, and i would point out, so do the majority of GM, ford and dodge pickup truck owners over many years with no problems to report. i think this buisiness of long idle cool off times is a thing of the past like a wives tale that may have had some merit back in the day but has since proven to not mean to much.

I agree.
I would not want to shut it down flat off the highway. IE you pull into a gas station right off the 401. But if I puddled around town after coming off the highway, I think a min or two would be max.
But hey thats just my 2 cents.

G'day
thank you all ,for advise technicians.
I can send to someone of you the pic to insert ?
I do not succeed to resize it.
for brownbear : I live in Italy,
have you the 1HZ in 105 ? km ? problems ?
Giacomo
If you have seen or repaired the damage that a 600hp cummins signature or a 520hp detroit has done from incorect shutdown you should take the warm down times quite serious. I have spent 8hrs on the side of the road trying to remove shrapnell from the intercooler and intake manifold after a truck driver thought that 3mins was an ok shutdown. This does not include the 2hr to remove and replace the turbo.
This is my opion, you are quite welcome to burn me!

In 6 years racing turbo 4wd gassers in Autokhana, sprint and tarmac rally we've never in our life needed to use a turbo timer.
You on the way home/about to turn the car off? Drive it nicely for the last 2-5 minutes and let the EGT come down to a respectable level. Anything below about 250 degrees in our cars is generally a great time to turn the thing straight off.
All our turbo's are watercooled more or less because the manufacturer recommends it. (They are not garrett turbo's).

i'm not about to burn you, but i do wonder what the heck is going on down there. i have been in the truck and heavy eqipment industry for many many moons and aside fromt he occasional meltdown or bearing failure i have not seen or had any problems in this area. i am around lots of trucks doing local work, city driving and short hauls, everyone one of them is over 450HP (mine is a CAT @ 550HP) and get shut down multiple times a day, some of the guys never turn them off all day, we are being told now its better to shut them down that let them idle all day. cummins is a pretty good engine but on this side of the pond we realy like out CAT and detroit 60 series.
sorry for any incorrect information
series 60 would have to be the best engine designed for simplicity, in aust we are up to DDEC 4 and 5 is comming out very soon. I work for a detriot agent (part time now due to running my own 24-7 bis now) we have alot of wanker drivers that toy with the computers and sensors (wizzers, setting so the jake comes on a full rev's, etc). The 10hr job I spoke of the exhaust impeller exploded due to excess heat during warm down causing the compressor impeller to unballance and sent shrepnell into the intercooler and intake. I can not be sure that the driver did not just turn the truck off(was a 14liter cummins set to 475hp) straight away, he told me that he set the timer to 3mins, got out to have a leak and check tires.
I am sorry if any information that I have posted seems to be suspect but I am only giving the information that I have been led to belive is correct. I encourage anyone that no's more than myself to set me straight.
On another note: we had an inter transtar come in the other week that had been rolled (driver error) the owner got insurance and we rebuilt it (straightened chassis, new cab/bunk, new brakes new w/brgs all round, new steer axle, tyres (about 30-40grand aust) the first trip it made, it was on its roof again, driver error! this is some of the s**t we have to put up with here.

i like your sig line juscruzin!
letting a turbo cool down is more common sense if you install one yourself, and get info on here about how to do things. When i pull off the highway i will gear down a bit but i tend to let the cruiser coast out of gear for a bit if i can, this drops the temps a bit more before the vehicle is stopped and is a little bit more reassurance that it is properly cooled down after giving it a few minutes. The wait time is small potatoes compared to the quicker arrival time with the 3B.

I dont doubt your experience with these big diesels but I saw a tech article in one of main aussie 4wd mags and they say the newer types of turbos no longer need the long cool down phase like the old ones.
I dont know when new or old is but thats what they said.
There is plenty of 105 with the 1HZ in Australia. Only real problem is the R151 gear box and front diff
