detroit diesel 12.7 vs 14L

They're rare. Popular for glider builds.

 

I did order it new. I was the same way, wanted one more non egr engine. Cat put a low nox program in my 99 model when they ran an overhead on it and refused to remove it (said they would be breaking the law by doing so), so I told them that was fine but my new truck would have a different engine in it. There was still time to change my specs so I switched from a 550 Cat to that 575 Detroit and it was one of the best engines I ever had. Would order another one in a minute.

I don't think Detroit really pushed it that hard because it was pretty expensive compared to a 12.7. But it was a lot more engine, too. The way I found out about it was I fueled at the Knoxville Flying J next to a Petty Enterprises truck that had one in one of those Freightliners that they had. Had my dealer check in to it and he found it in the available engines screen. I don't think he knew it existed either, and like I said earlier I went to several Detroit dealers that had never seen one in person. The techs would come over and look at it. LOL

 

I also read somewhere that they could upload an off-highway program for marine/industrial use that could crank them up as high as 800 hp.

 

Or the OP could compromise and get a pre EGR 14 L series 60. Had one of them unicorns in a 2001 Sterling

 

I have a 2004 12.7 Detroit. The company I pull for has a few 14l's . I pull the same loads they do and get much better fuel mileage and I have fewer repairs. Plus, I easily outpull them on the hills.

My truck does have the EGR. On heavy loads I get around 6.3 mpg. light loads I can get over 7 mpg.
The 14ls in our fleet get 5.2 to 6 mpg plus they don't last.

I am thinking of doing that egr delete trick. does anyone have experience with that?

 

Try the ugly fix.

 

The 14 Litre Non EGR Series 60 was the ONLY series 60 sold here in Australia between 2001 & 2007..

 

they were not ONLY sold in australia. theres alot in usa. swaan has a 14L non egr glider

 

You misunderstood what he said. He didn't say they were only sold in Australia.
