Engine swap: 2004 - 2006

I am thinking of pulling my tired 2004 6.0 Powerstroke and putting in a 2006 6.0 Powerstroke. I know that the 2003 had a lot of diffences I was just checking to see if the 2004 to 2006 engine swap would be a doable swap? If not would the heads work from a 2005 or 2006 on my 2004 as a backup plan?

Thanks for your time,

Joel

If the engine is complete, you should be good. The heads would work but you would need a dowel insert since the 06 heads would have a 20mm dowel size and the 04 heads would have an 18mm dowel size. (PS. You would NOT be able to put your 04 heads on the 06 block.)

Thank you about the note about the dowel sizes. What about the wiring. All sensors in the same place? Would I be able to use the 2004 ecu with the 2006 engine?

Double check on your 04 that your ICP is in the passenger side valve cover. If it is, your sensors are in the same place. If it isn't, you have an 03 engine and you might need a new engine harness.

My ICP is on the passenger cover? Where is it on the 2003? How about my ecu from the2004? Or should I buy the 2006 ecu from the engine for another $200?

ICP on a 2003 truck is by the turbo...

Yours is good to swap to that 06...

IIRC all you need is all of the matching computers..(I assume you have ALL of the computers from your 04)


The computers don't care what year the block is... they just need to talk to each other

The 2004 is all together and running, just need new head gaskets. The 2006 is also in a running truck but he is pulling it to go to a cummins and offered it to me for a pretty good price I think. I was figuring to do the head studs on the 2006 and then do an engine swap to limit downtime. So as you guys say, all I need is the engine and I'm good to go?

What about the hpop or ipr? I thought they were worst in the 2006 trucks compared to the 2004 truck but can't remember.

03 HPOP is the bad one IIRC...

IPR is teh same...What you need for the 06 is the STC fitting on the HPOP

Make sure to run OEM Head Gaskets and follow the ARP torque down instructions provided WITH your kit...They were changed as some point

Ok stupid question here. Why the change back to OEM head gaskets? When I had mine changed out about a year ago all the talk here was about using Black Onyx. I have gone from feeling fairly secure to not so after reading recent post's.
thanks
