Engine shopping What can I put in my 2005 W-900

All I have ever heard is it is illegal to alter the emissions on a truck. I don't know if I'd be worried about law enforcement so much as I would about shops not working on it in case of an emergency. I've never seen or heard of DOT checking emissions except in CA. But every dealership, and some independent shops, I have walked into in recent years has signs posted that will not work on trucks with emissions altered. I can't say that they would indeed follow through with that, or view an engine dropped in the the same as de-rating. I wouldn't want to chance it unless I ran a small region and knew where I could take it beforehand.

 

Legally? Emissions have to match what came in it since it’s not a glider. So 04 and newer would be your emission tier.

 

Acert is an emissions setup. Cat's version of an egr motor if I'm not mistaken.

 

You can put any engine you want but not at a dealership.
Will it meet emissions most likely not.

 

Just put another Acert back in that’s your best option

 

I’d hate to pay for the labor to swing a motor at a dealership.
Around here it’s $180ish a hour.

 

EGR is not pre-emissions, it's just not as bad as what came later. DOT technically doesn't get involved in enforcing another alphabet organization's regulations, but it could happen.

 

Legally speaking you can put any on road engine in there as long as it is not a lower emissions tier than what the chassis left the factory with originally.

For the sake of simplicity just drop in what came out of it. Swapping to something else is going to complicate things a bit.
