So, looks like something got through my air cleaner and chipped the leading edge on all my turbo blades... praying that none of it settled in my engine... but it's not providing enough boost to help me pull hills very fast.questions:1. Where can I find a turbo for my Cummins? Shop here in TC said there are none available from factory or any shop in the USA.2. How hard is it to change out a turbo? I'm pretty mechanical and think if it's just a R/R type of deal that might not require job specific tools, it'd be something I could do. Thx for any info.Larry

Try an authorized Cummins shop. Perhaps youtube has a vid on this.How do you know this? ECM readout? I'm getting codes that say my turbo is failing, but my Cummins 8.3 ISC runs just fine.

There are lots of made in China turbos available. Do a little Google searching and you will surely find one. You will need the numbers from the plate on the turbo. I have a Chinese turbo on my VW diesel engine in my Samurai toad and it is fine.

call cummins and ask them. once you find which turbo you hae u can search ebay to get pictures and a idea of the assembly.there are places that rebuilt turbos.if your blades are not chiped baddly the turbo should work . if you dont have good boost preasure there may be some other issues. the dump valve maybe sticking. thats easy to check.

As far as finding it, again, youtube. It's a round thing.

Thx for the replies. I'll dig it out of the snowbank one more time and take a look underneath. I think I might be able to get the numbers from inside as well, at least that's what Country Coach Tech said.

"chipped the leading edge on all my turbo blades... praying that none of it settled in my engine"

Does not sound right to me.

What caused this chipping of the leading edge blades of the compressor? Those chips have nowhere to go other then the cumbustion chamber! Unless you have a C.A.C? (Charge Air Cooler) Perhaps the chips settled in the C.A.C.

My turbo on my 8.3l Cummins is setup as follow's;
Air enters the Air Cleaner
Piped to the compressor side of the turbo.
Enters turbo, get's compressed (heated as well)and then piped to the Charge Air cooler, (between the radiator and the AC condencer) gets cooled (condenses) and then is routed to the intake.

So, If my turbo had chips on the leading edge of the compressor all those "chips" whould be heading for the Charge Air Cooler. Perhaps stuck their! No other place for then to go other than the intake manafold. That air cleaner is the LAST line of defence.

I'd be looking at what caused it so it cannot happen again.

Keep us posted.

Call the guys I posted the link to......they will give you alternatives. They sell to builders for twins and triples setups as well as stock stuff.

My guess is that you have another problem besides the damaged turbo. If it was just down on airflow causing your power loss, there would excessive smoke from the exhaust.

Got the number.

OK, guess my cummins has a turbo #4025397.

So, unless there are any upgrades since its installation I'll have to do a search along that line.

Any one know of alternatives to stock?

Thx

There were no codes thrown other than a quick orange light that said "engine warning" but it didn't leave any codes that I'm aware of. When I ran through the procedure at my keypad it didn't show any.
Your keypad? Not sure i know what that is..

Cummins ISL 370. No School here again this a.m. so getting turbo #s will have to wait til I get wood hauled in from back 40... and dig out with the tractor. Sure wish we'd have made it out of the frigid north 3 months ago. Events pile up to keep me here... must be a reason.

I'll post #s

Just rebuild it if the housing is not damaged but after doing the center section have it balanced. Rebuild kits should be easy to find. What turbo is on it? Post info off the tag and aybe we could find one.

What eng ? I know it's a Cummins but which one?

You can buy rebuild kits and do it yourself. Look in Cummmins-Dodge forums. Replace the air intake all the way to a new more efficient air filter.
