2002 motor swap

Posted

Recently purchased a 2002 ho truck and got a good deal because the motor isn’t happy ( knocking and crazy blow by). To solve this problem I’ve purchased a 2000 model engine. Forgive me I am learning these 24s I’m used to 12 valves. I know now that there’s the two sub generations 98.5-00 and 01-02 and they don’t interchange very well. 
 

My main question is am I going to run into problems with the swap even with swapping the pcm/ecm/ engine harness ? Got a steal of the 2000 engine everything for 800$ so I really want to make this work .

I know the text is dark. I'll try and fix it.

 

 I’ve read the dark text . Sounds like my swap should be fine then , fingers crossed

Better read again...

 

 

“For the proven method of swapping sub generations, you WILL need the ECM, PCM, full engine harness & PCM at a minimum”

 

I have all this , and worse comes to worse can grab the trucks harness as well , dash too . Only thing I can think of that won’t work is cruise control after the swap

So to conclude, only things swapped are as listed

*2002 engine swapped to 2000

*ecm/ pcm from the 2000 donor

 

I didn’t list the engine harness because who pulls the harness off the engine when they pull it
