Replacing EGR ISX with Non-EGR
Curious about those with more mechanical /technical knowledge than me. How difficult would it be to replace an EGR ISX engine with a pre-EGR ISX? Are different wiring harness' required? Anyone done this or seen it done?
I have the EGR unplugged (with excellent results) on my '06 ISX. But when the time comes to rebuild, was considering getting a pre-EGR engine assembly and rebuilding it instead. Then replace the current engine with the other engine. Any thoughts? California not an issue since I do not go there. |

It IS ILLEGAL to remove any diesel engine that meets post-'04 (EGR) emissions standards, to be replaced with an engine that meets previous, non-EGR (pre-'04) emissions levels. Also, it is ILLEGAL to remove a '96 (OBD2) gasoline engine and replace it with an older engine that does not meet OBD2 certification; examples - OBD engines... or 'carburated' engines for the performance guys. ...just as a couple of examples. Your example with the 2010 Columbine is a loop hole used by truck manufacturers to get away from selling the currently undesirable '10 compliant engines; they spend epa emissions credits to certify these vehicles. I have the EPA documents that describe this regulation in great detail. Take a look here (U.S. Environmental Protection Agency) or contact them ... however, if you plan to go ahead with the swap either way, I wouldn't leave your contact info ;] |

Your ECM would need a new, pre-EGR program. It might be easier on the engine side if you had the ECM to match the older engine, but you may then find differences between the OEM connections from the truck chassis, if the chassis's are the same. |

But if you can prove me wrong thru the documentation, you could also make a killing proving the OEM's and third parties are wrong also. Since there are no government lawsuits to date against companies like Fitzgerald, I am skeptical of your claims. |
im a little confused.......you say you have a isx egr 2006 engine? was it a late model egr isx? cuz most started 2007?
anyway u probably have got info now ...but u do know that the harnesses for pre isx egr are differrent than egr models the plug connections are completely different..... egr model 2006? to 2008 are 1-power plug 1- 60pin plug and 1-50pin plug whereas the good old pre egr has 3 of the same plug connections. my 2 bits anyway dj |
confused
Yes you are confused. You are confusing egr with dpf maybe. I also have an 06 egr Isx and I am positive of that because I disconnected it myself.

That's some good info for someone who is selling #5200$ re-programmed Cummins ECMs..... seemingly quite knowledgeable about the product :-( |
I too have an '06 EGR ISX (unplugged like Copperhead) and was thinking the same thing about JBALL's post. Scary.
