12.7 to 14 litre

Why would you want to? Isn't a 14 Litre a EPA truck? A EPA engine to overhaul is around 30k You can pretty much rebuild a 12.7 with new everything for 15k... What kind of power are you talking about?

 

AMEN!!!!! I have a 14 liter and wish it was a 12.7. No more power than my friends 12.7 and makes nearly a mile to a gallon worse. And yes it's deleted.

 

a EPA engine isn't cheap to rebuild.. Wasn't sure if they made a 14L That didn't have that Emissions Junk. I Was in a Detroit shop on tuesday getting parts for my APU. They had a sign posted on pricing on rebuilds. 12.7 WAS the CHEAPEST BY FAR. These other Detroit engines were very high over 25k..

 

Yeah im rebuilding my isx engine... Lost over 1.5 MPG right now with because of oil usage.. Its gonna be about 22k With a new head.. No way im reusing a head. This is at a smaller shop thats not counting cam or rollers if anything else is found bad

 

a rebuild on a 14l around these parts is 15-16k

 

That 12.7 can't just be turned into a 14L. You already have one of the best engines out there. I would just get it rebuilt and put some good upgrades like a bigger turbo, polished and ported intake,ect,ect. Then top it off with an awesome custom tune and that truck will rock.

 

Detroit made a Series 60 in 11.1L, 12.7L and 14L. All were available before EGR.

BTW, the EPA has been regulating on-road diesel engine emissions since at least the early 90's. Why do you think they went to electronic controlled engines? Mechanical fuel pumps were not precise enough to control the emissions output, so electronic unit injectors were developed for more precise fuel control.

 

There’s a good Facebook page on Detroit S60 - I just read and absorb most of the time.

You might get some good knowledge out of it.

 

Isn't it drilled for piston oilers? Good ecu tune and s475 is a good starting point
