CNG or LPG on eco boost?

[Imabass]

Are these engines easily retrofitted to run cng? With the small bed, running a cng or lpg tank in the bed would be killer for cheap driving. I am fond on lpg conversions myself. I converted a camry to run on propane and I saved buckets of money. Would the 2.5l hybrid be a better candidate for conversion?

I don't think this is the right forum for these kind of questions From what I know about CNG conversions I believe they prefer higher compression. The 2.5 hybrid has a 13:1 compression engine, so I would think that is the better option in that regard. the Duratec/MZR engine has also been around longer and has a better aftermarket if you needed parts to support your build.

Now, I have no idea if the engine management would agree with what you wanted to do to it... Best of luck!

I would have to think the hybrid would indeed be the better one. Very easy to swap to CNG on normal vehicles. But I’d have to believe it would require a good amount of tuning and cost to convert the ecoboost. Plus you would more than likely lose the power you choose the ecoboost for.
But the hybrid would be the cats asz.

If you are trying to get better mpg, definitely go with the hybrid, a CNG conversion will leave you disappointed. I have been filling propane tanks since 1982, at that time all the delivery trucks ran on propane, the benefits were they got their fuel at wholesale & oil changes were 50% longer because the oil stayed so clean. The downside was 10%-15% reduction in power & it used more propane than gas, this was when the cost of propane was 75 cents a gallon & gas was $1.25 so it was about equal in cost. You can't just get a CNG vehicle filled everywhere, it's like an EV you have to search for a place. DOT standards for tanks are also very specific, you can't just throw a camper tank in the box & go. By the time you paid for the proper conversion you will have spent enough to buy gas for 40,000 miles. Funny thing about the beginning of this story is that the company changed out their delivery trucks to diesel in about 2005, when I ask why they said it was now cheaper because diesel per gallon was less & they got better mpg's, then the recession of 2007 came, the price of diesel doubled, but they were now stuck with it, today the wholesale cost of propane is about half of diesel!
