dodge ecodeisel or ford f150 ecoboost

Yep but lets see how many 100,000 miles they go , we know the typical truck V8 engine can with proper oil changes make it without too much hassle , but how long will the turbos go , might do great , or might cost $2300 or more .

Ford F-15 EcoBoost Replacement Cost | Tundra Headquarters Blog

What's the difference between a diesel turbo and a gas turbo? Diesel are touted for longevity, even though they use turbos, where GTDI engines get blasted for having turbos. Seriously, what the heck?

Not to mention, diesels are harder on turbos due to the extra soot coming out the exhaust.

The ecoboost uses both oil and coolant to preserve the longevity of the turbo.

Turbos go for hundred of thousands of miles. It's two wheels linked by a floating bearing in oil. The bearing and thrust washers is the only wear item and the kits to rebuild a turbo is less than $50. Why buy two new turbos?

I regularly take out and clean and inspect the turbo on my 6.0 all the time. Not once yet has it needed a new bearing. The soot on the VGT vanes are what make a turbo over boost or under boost. But it only takes 20 minutes to clean everything up. Gas does not produce the soot like diesel, so I fully expect to not even touch the turbos on my ecoboost.

The turbos on these rigs are not what I'm worried about. It's the high pressure fuel system and it's related components.

Another good point about them HHR ! ............And Snobdds I guess all the ecoboost owners are mechanics like you and besides drilling holes in the turbos will be doing their own maintenance on the turbo bearings .......I'll stick to a more simple V8 that gets better gas mileage when under load, and still plenty of power.

With turbo gas engines, isn't it the same "high pressure" fuel system as found in all non-turbo gasoline direct injection cars and light trucks? The pressure is high, but nothing like a common rail diesel.

I don't think the 5.0 Cummins will get near the MPG of the Eco diesel. I feel ram got it right with the half ton diesel go for mileage. If you need to tow heavy look at the 3/4 and up offerings.

You won't be getting g 30+ mpg...20+ yes but 30 ain't gonna happen

Yes it is.

Yes it is.

One of the differences that may affect long term reliability is the lubricity of diesel versus gasoline.
... will these DI gas injectors/pumps make 200k miles consistently?

I hope so, they're found in almost every car sold today; but I guess time will tell.
Weren't there also reported some issues with deposits building up on intake valves?

Ok so you don't do you're own stuff; which is fine, but I think you missed the entire point. The system has both oil and coolant keeping the turbos in good running health for a long time. Plus, if the Turbo does go for some reason, pay someone 2 hours of labor to pull the turbos and rebuilt them for $50 each. At most you in it for $400. The power they add to the system, especially if your at altitude like I am, is far greater than the benefits of a simple design.

Remember, a naturally aspirated engine looses 3% of it's power for every 1,000 feet of elevation increase. I'm at 7,000 feet above sea level, a naturally aspirated engine is already 21% down on power up here. With turbos, I'm only loosing maybe 2% from elevation. That is a huge bonus that many just don't know or understand that fact. I've been waiting years for a major manufacturer to finally produce a factory turbo set up in a truck.
