    My CPL is 1580. Injectors, turbo, different ECM or ECM flash, different pistons? Fixing to tear this engine down and rebuild.

    I’m not to where I can look at my CPL book right now, but should be home tomorrow night. Do you have a certain CPL # you plan on building the engine to…?

    I’m assuming the 460hp is the tallest horsepower in the Celect, line up? I do not have an idea what CPL in Celect + would be the easiest to go to, north of 460hp. My thought are, I’m gonna do new injectors, turbo, freshen or replace ECM and in frame. So,……… what can I achieve up to 525hp?

    Is there a pdf that will list part numbers for my current CPL 1580, so I can compare it to a 500-525hp C+ CPL? If my 1580 is 460hp, seems to me there ought to be a few things(injectors, turbo, ECM flash) so that essentially this 460 could be “turned up”, 10-15%?? That would have it in that 500-525hp.

    You gotta go to Genuine Cummins Parts

    Enter your serial number and it will show you all the parts you have.
    Do the same thing in a different browser window with a serial number of an engine with 2592 cpl, then compare
     
    mile marker 27 Thanks this.

    You gotta go all the way up to 525/1850, with 500/1650 you won't feel much difference

    Those are both Celect + CPL’s, correct? Were there any Celect CPL’s with higher HP, than 460?

    As far as I know, yes, 460 max for Celect, but you can make it a Celect plus. I believe you will need a new harness and a barometric sensor, plus the ecm programming.
    You can join the N14 group on Facebook, lots of knowledgeable people there

    So, there’s nothing mechanically that can be done to achieve +460hp and there’s nothing really, outside of changing the ECM to a +, to gain anything either?
    I guess this why I like the old mechanical engines best. I really wish I could just convert this truck to a mechanical engine.
