Well my engine now has 5100hrs the trans has been replaced and the engine still seems 2 be running strong and i just hit 160,000km so my real question is should i start saving for a new turbo from all that idle time? And how much does a new stock one cost? And would i be able to run a fleece turbo on my truck with the mods i have? Im not real crazy about power if im going to buy a new turbo i want a fleece. I love how they sound. But im worried i might wreck somthin any info would be
appreciated. Thanks

if not over spun and never run dry it should last a pretty long while. with all your mods you should just get the aftermarket one. new OEM ones are about 1800.

off topic....
you have Edge AND EFIlive? how does that work out..or do you just use the monitoring features of the edge?

I have 260000+ km's on my dmax still going strong. Hope to get 500000+ km's out of it. No turbo issues to date.

Yeah i just use edge for the gauges now. Sum times i kick it up to level 2 for extra fule mileage on the highway depending on the tune im running with EFI. But yeah i would be better off getting an aftermarket turbo they arnt to much more money then OEM. And i always wait till my EGT's are under 300 to shut the truck off.

its fine. the duramax turbos are very reliable.

Even better, you can pick up a nice used one for 300-400 bucks. :cool:

Well thats not bad are they pretty hard to change? Or would i be better off getting a dealership to swap one out? I do have experience in rebuilding gas engines and what not.

assuming the metric system hasn't changed when I wasn't paying attention that is just under 100k right?

You're turbo should be good for 3 to 4 times that with proper care, maintenance, and not beating the snot out of it.

yep just under 100,000 miles and i know thats not to many but 5100 engine hours is damn near equivilent to a truck with like 180,000 miles on the turbo. Thats the olny reason im concerned.

i could be wrong but at idle i dont think your doing anything damage wise to the turbo.its not being spooled.

I'm at just over 150K miles, (251km) and I'm at just under five thousand hours so yeah yours has a little more hours than normal but not a whole lot more than mine and I can still make her whistle nice and loud pullin up the hills.

Oh okay i wasent sure if they wear out or not from normal idling. I also opened the vains at idle so its not spinning so much when i dont need it to. Should have lots of life left in her.

If the turbo is run within its limits, and not run hot, or oversped, it should last the life of the engine. Idling does not shorted the life of a turbo whatsoever, and being a watercooled unit (I believe the VVT's are...correct me if I'm wrong here) You shouldn't even have to wait for EGT's to drop below even 400 before shutting down the engine. The turbo on a D-max is a PAIN IN THE A$$ to change out, but it is doable for anyone with mechanical knowledge.

vvts are oil cooled

116k HARD miles here and going strong. You should have no problems with proper care/maintanence making that turbo last the life of the engine. Give it it's proper cool down time after running it and keep the oil in good condition....you'll be fine.

DON'T let the dealership touch your truck if you value it!

My friend has a 04 LLY,with 165k and all of that 165k has been full throttle runs,pulling heavy trailers....at full throttle runs.His turbo is the same as it was when I met him with 8k miles.So they can take a beating and keep on going.

I would say...your safe!!!!!

oh I forgot.12 miles to 80k was hypertech on 90hp.

80k to present is bullydog triple dog,on racing.

Hmmm well now that i know my stock turbo is damn near bullet proof my other question is will a Fleece turbo bolt up to my stock engine? And what are the hp gains from the fleece turbo alone? Sorry for going off topic i just dont want to start another thread.

everyone one is saying "if you maintain it" what maintence is needed on our turbos?

That would just be keeping the oil changed/clean and letting it cool down by idling after a heavy run. The turbo still spins after the truck is brought to a stop. If you don't give it about 30 sec to come back down when you stop before shutting down, it can put strain on the turbo. That's all.....

how long is good to let it the turbo cool down? just give it 30 seconds like you just said or more?

30 sec is a good general rule, but I let mine go longer if I have been pulling my horses or my RV. For example, if I stop to get fuel, I don't shut it down. If I know I am only stopping for a few minutes or even 10, I still let it idle. I also use my Pyro gauge to give me an idea of when to shut down. Once it gets to about 250*, its ok to shut it off.

Keep in mind that the idling you do in the parking lot to travel that last 50 feet or yards or whatever will more than likely cool your engine sufficiently to shut it off... especially pulling into a truck stop or something like that. Probably 95% (or more) of us will never have to worry about specifically allocating time for things to cool down before we shut 'em down; it's the guy hooked against another truck on a tug-o-war, or some guy pulling a sled or some other such strenuous effort who should specifically allocate time to cool before they shut down...
