Engine swap or just sell truck?

Sell the ISX and put the C15 in the truck.

 

Sell me the c15

 

It should be a fairly straightforward swap. Maybe some harnesses but that should be about it. You’re only talking a two year difference on model years, and it was before everything got complicated.

 

Wouldn't be a hard swap but personally I'd just rebuild the isx and sell the wrecked truck with the cat in it. Will still fetch a decent price if not completely totalled

 

You can either use the other truck as a donor or there is a company who makes conversion harness that I can’t think of right now, what motor is the 04 an Nxs? I might also get some ball park quotes on rebuilding the isx

either way I personally wouldn’t give up a non DEF truck until the government forces me to

 

Build Packages

 

Can you even legally swap the engines? Isn't an 04 and 06 two different EPA years and not allowed?
(Or am I wildly off again?)

 

Depends on which motor is in the 04, 03/04 was the cross over year depending on what was ordered with what or what was still sitting in the spare parts room

majority of them should swap fine

 

I thought you just couldn't modify or remove epa equipment from an engine. So if you take out a emissions engine and install a non-emissions engine, you didn't touch the emissions. Because the new engine doesn't have any. Thoughts?

 

If that were accurate, nobody would be grumpy about tossing a 3406 a,b
in a 2020 model.
This is not the case anymore, gliders were the only way to do that and seems that that has ended.

I AM a little curious if you slap a brand new engine (2020) in an old say 99 what you can and cant do to it though

 

How much downtime are you looking at ?
And what would that cost in lost revenue?

might be better off to find another truck and sell both of yours . , keep the lost revenue downtime to less than a week .
