So my envoy is still running great. But I cant ignore the fact the engine has some miles on it..
So I am gathering info on my engine and possible replacement, when that time comes, if it ever comes.
I started here... LS Engine Compatibility
I have a 2004 GMC Envoy with the LM4 VIN P 24x V8. These engines are a direct swap for years 2003-2005. Aluminum block.
I know the 2007 and up LH6 will not work as the reluctor was changed from a 24x to 58x.
I know the 2007 and up LS2 will not work for the same reason.
My first question revolves around the 2005-2006 LH6 and LS2. Both are the 24x, and these engines will have the DOD/AFM. Since my current engine wiring harness doesnt have this option, this should not matter. Am I correct in my thinking that all I would need to do to use the 2005-06 LH6/LS2 engines is swap the intake and fuel injectors over? Or are there other challenges I need to be aware of.
I would much rather go the route of the LSA/LS3/LS7/LS9, but that would be a headache adding in the 58x wiring, ecm, and likely having to deal with the AFM/DOD, reprogramming for other things, adding a TCM, etc.
When this does happen (if it happens), the usual stuff will be happening while this goes on, upgrading the diffs from GU6, to GT5. Replacing motor mounts, or other odds and ends.
This is just me gathering info for a "what if" situation. This is not something thats going to happen any time soon.
