life expectancy of stock turbo
 

i'm thinking about getting some 90hp nozzles for my truck and i'm just wondering how long everyone things my stock turbo will hold up

I would say, your going to need to upgrade it, along with a lift pump, and your going to have to run some gauges also.

i know i'm going to need to upgrade it i'm just wondering what everyones thoughts were on how long it will last ?

Depending on how you drive it, last about the same if you left it stock. I'd say around another 50k mi from where you at. BTW, how many mi have you got on her now??

77000

200000 on my turbo, checked the end play on the shaft everythings still tight.

I just took a hy35 off at around 268,000 miles. Truck was stock for the first 250,000 miles. Injectors and some sort of box the last 20,000. Turbo feels as tight as a stock one. I'm thinking with good oil change and not to much abuse it could be longer than the motor. You actually are suppose to have no metal to metal, good clean oil ought to keep any wear out of it.
My hx 35-40 probably has 125,000 miles on it in three different trucks. I don't see any signs of wear in it. I am meticulous about oil changes so that may have something to do with it.

Mines still spooling just fine with 411hp to the wheels. It has 182,262 miles on it. Granted it has a good amount of play up and down and you can see where the blades have scraped the housing just a little over time. Its had the chip and all for 60-80k miles. Ive run the dog crap out of it though. Im trying to get all I can possibly get out of mine though. That may sound stupid but Ive seen quite a few go out and not hurt the engine internally.

they say in the diesel mag i read that stock turbos can do about 400-500 horses.... but that all depends on how you drive, maintnance and other factors...

I ran mine with 90 HP Nozzels for about 60k miles and had no issues. After I upgraded it and sold the stock one the new charger blew out a bearing at the track at mile 1400

I talked to the guy who bought the stock charger from me the other week and he said he has now 170k on top of my 60k and no issue, tight as new
