Question about switching a C15 accert to a 6Nz

An 08 pete with an acert still has an egr on it from factory unless it was deleted you would need an 03 to not have one on it.And I think an 08 still has the dpf and the burner on it also, you need a 07 or earlier for just a egr.

 

Go 1999 or older. Not only are they better trucks/motors (and mostly mechanical, so if you are mechanically-minded, you can do a lot of work yourself) but you won't have to run elogs when they become mandated.

I've run both MBN and 6NZ C-15's and can tell you they are amazing engines. But I hear wonderful things about the 3406E and B.

 

Legally you can only replace with an engine that is the same model year or newer than the truck it's going in. Now with that said, if the states you run in don't do testing you can pretty much do whatever you want as long as you keep your mouth shut and have a mechanic that will work on "non standard" stuff. If it was me I'd just get a pre '00 truck to avoid all the new laws coming down the road.

 

I have an ACERT in my truck. No EGR.

C15 ACERT motor uses what called the Miller Cycle to do pretty much the same thing.

Need help! Have a 2007 Kenworth T600 that had C-15 accert engine. We put a 2003 C-15 6NZ engine in it. Everything is working fine besides the gauges on the dash that have anything to do with the engine like RPMs, oil pressure, ect... When we hook up the computer, all the gauges work on the computer but not on the dashboard. Anyone know what could it be?

 

I seem to recall that the 2007's used a multiplex system rather than mechanical gauges. The ECM will still read the info like you say it does, it just can't communicate that info to the gauges on the CAN network. Not sure the best way to remedy that. Maybe have to replace the engine related gauges and wire them directly to the respective output pins for those parameters on the ECM? Or run install seperate temp/oil pressure sensors and run them to mechanical gauges?

I'm sure there are people on here that know much more about this than myself.

 

Did you ever find out what do about this? I’ve ran into the same issue no gauges or communication on truck side, engine runs but no gauges, newer flash? I switched from sdp acert to 6nz
