Ol'Scool 
Have owned N14 red tops at 460 horse and 525 horse but never a black top before. I dont have complaints with N14's other than rebuilding at 500-600k, lower fuel mileage, and ECM's going out. Show with that said, I have recently acquired a straight truck with a 1996 built 370 horse Black Top N14
that has 150K ORIGINAL miles heres the issues, what can i bump it to?? I would actually like to go to 525+ but have been getting mixed information as to if the "non-accessory" components in black top n14's and red top n14's are the same do they have the same internals????? seriously, any information would be more than greatly appreciated!! I do thank everyone in advance for any and all information and discussion!! cr39
Liberty, MO Kansas City Cummins is located 1 mile east of I435 just on the south side of Oceans of Fun-Worlds of Fun, might be Parvin Road, not sure. GM Guy
NW KS/ SC ID there is talk about main bearing caps and cylinder heads fretting much above 525 hp, but it is all heresay, no experience. pete37921x
NE SD Short answer not simple, almost impossible. May involve camshaft, heads, pistons,injectors, I don't know exact specifics but we run Cummins in our trucks (my part) and our shop is Cummins dealer, my partner and or boss owner(shop) has built and overhauled our N 14's. It's far easier to start with a red top if you want big HP. look for a different engine or leave it Ol'Scool

It's far easier to start with a red top if you want big HP. look for a different engine or leave it may?? thats the real question, do red tops actually have different cams, pistons, etc??? or just rattle canned red valve covers?? one not so reputable source told me they were "probably different" on the inside another much more reputable source told me he thought they were IDENTICAL other than injectors, fuel delivery and timing, intercooler and turbo setup (and red painted valve covers), but said he "wasnt 100% sure" thats why i asked because i was hoping someone might have some info or at least some knowledge that might lead to some info pete37921x - 5/9/2013 00:44 It's far easier to start with a red top if you want big HP. look for a different engine or leave it im assuming that your assuming in making that statement that the internals are in fact definitely different, because in my situation, i honestly dont think it would be easier to start with a red top if theres not any real difference other than fuel/air... becuase to start with a red top, and have as good of an engine as the 150k one ive got, id need a freshly rebuilt one, so that would put me up around 5 figures not counting the actual horsepower adders and leave me with a perfectly running 370 horse non red top if i didnt end up giving it away as a core but thats the whole reason im asking!!

Leeds, North Dakota Your CPL # gives specs of how your engine was built, if it was a non-electronic engine could get you some numbers, electronic almost impossible with epa regulations, whatever engine was set at from factory it is illegal to modify from a qualified shop, Scott. jedeka
Boone, Iowa Call Pittsburgh Power and talk to them. They are very knowledgeable with high performance Cummins engines. Have your CPL number in front of you before you call. Phone # is 724-360-4080. combinejockey

Marion,ks I had a 93 KW with a n14 blacktop I had it turned up to a 460hp,1550 torque setting last I new it was still going at 1.3 million miles. It needed injectors at 600,000. It started life out at 330/1450 thet told me that 460/1550 was the max settings. it. Spent most of it's life turned up to 400plus horsepower. Would not be scared at all to buy it. illinidirtfarmer
WC IL IMHO, 370 horse is plenty for a straight truck anyway. But that's just me. IADAVE
I would think that it was probably a fleet truck set up at the lower hp but built so that the next owner could just have the specs reset with a computer. Edited by IADAVE 5/9/2013 20:38 RodInNS
As far as the Jake goes... I'd think you could change a lot of shoes for the cost of screwing around and adding a jake. Sometimes a cheap old truck is best just enjoyed as a cheap old truck. Rod Is the N14 Red Top a good engine?The Cummins N-14 is a great engine; quite possibly the best Cummins engine ever produced. These engines are the stuff dreams are made of if you're an old school guy looking for reliability. No doubt, the N14 is part of “1,000,000 mile club”.
How much horsepower does a N14 celect plus have?The Cummins N14 is capable of producing between 310 and 525 horsepower. The N14 is capable of generating 1,250 to 1,850 foot-pounds of torque at 1,200 RPM. Cummins released the upgraded N14 in 1997. This was the Celect Plus fuel system, but looked similar.
