99' motor into a 02' Help !!

[Smokin 6.0]

I'm putting a late 99 motor in my 02 and was wondering it anyone could tell me what all I need to do to get it to work right.. Can I just swap motors ECM's and IDM's and be good or is there more to it any help is appreciated.. Thanks

You shouldn't have to change the pcm or idm..

They are the same motors. Direct swap

Don't use the 99 engine harness. Alternator won't charge and the coolant temp will do some funny stuff.

:whs: Use the 02 engine harness and drop the 99 engine in. No need to change PCM or IDM like was stated before.

Youre probably gonna have to swap your coolant temp sensor. Ive ran into issues before, there were like 3 different sensors... or you could get lucky and have no problems at all

FYI if the 99' motor happens to be out of a van you have to change a couple things to fit it in a super duty

The motor is out of a CCLB 99' I was just curious because I thought that 99 injectors were single shot and the 02 injectors were split shot.. Thanks guys that helps a lot !!

As long as its late 99 & not early 99, it's the same.

Need to double check but I am fairly certain it's out of a late 99.. if it is out of a early 99 what all do I have to do to get it to work in my 02 ? Thanks guys

If its an e99, for it to be exactly like your other motor, you will need to swap injectors, intake plenums and spyder, and e99's dont have the aih's, so you will either have to swap over the bracket from the 02 to keep the aih in tact (I ditched mine and just heat shrinked over the power wires terminals going to the aih relay and zip tied them to the rest of the harness and swapped the early 99 bracket that only had the glow plug relay )
You will also HAVE to use the 2002 engine harness. thats it iirc, but I also havent really messed with 7.3's in a bit

 

[moose99psd]

to know for sure, pop a valve cover and look at the injector code. ab is early 99 and ad is late.

 

[CSIPSD]

Both are split shot injectors however...

I put a 99 engine into my 02 with no problems. Of course I switched injectors and other parts off my engine, but still the same PCM and IDM.

Its a early 99 do I just need to keep the 99 ECM, IDM and 99 engine harness ? And everything else on the truck will be ok or is there more that I will have to change ? Thanks guys

You will need to swap intake plenums, spyder, figure out what you want to do with your aih relay, either delete it or install the bracket off the 02 motor for both the gpr and aih relay. You will need the 02 engine harness, and I would swap injectors, aktgough either set will work. E99's had 15 degree hpops too, so you may want to swap that over too. Thats all I can think of right off the top of my head

Turbo setups are different. RH manifold and turbo will need to be changed to stay 02 style.

Duh! How did I leave turbo out?

 

[PSD715]

Pedistal?

RH manifold may not need to be changed. Mine didn't.
