Default Cummins R2.8 engine swap question(s) for a 96 D1

Hello-

I've always wished one of my D1s was a diesel and have been researching an diesel engine swap for about a year now and although I like to do regular (modest) repairs I do not have the time, tools & expertise to pull this off.

I thought I would end up with an old 300tdi in one of my trucks but then I stumbled on the Cummins r2.8 videos on YouTube and watched the Cummins Cruise thinking, "That could be my D1!". This week I finally got around to calling a shop in Colorado where I live for a quote- the shop just completed an r2.8 swap for a Customer's Defender 110 and posted the video of the truck's maiden voyage- it looked and sounded great. I gave the sales rep my info and he said he'd get back to me once he talked to the shop's owner and gathered the information.

I knew the engine cost around $7600 because I can buy one directly from Cummins and have it delivered to my house so I was expecting the estimate to be North of $10k and (hoping) around $15K- which is not a small amount of money in my book.

When the shop rep called me back he said two things that squashed my enthusiasm:

1). That the engine was not "emissions legal" in the state of Colorado and a lot of work would be needed to make the conversion legal. What!!??
2). The total bill would be anywhere between $40-50K (with $10-15K in labor). WHAT!!??

Surely others have looked into such a conversion. I ran this idea by a buddy of mine from California who is a much better wrench than me and the first thing he asked was how I was going to pass emissions in Colorado. I assumed (wrongly?) that because it was a new crate engine going into an old vehicle there would be no issues other than writing a check (I'm old school) for the work.

What am I missing? $40-50K for an engine swap ain't gonna happen.

Anybody else in Colorado looked into a Cummins r2.8 for a D1 or other vehicle? I'd be interested to compare notes.

Regards,

brian

They don't mention colorado being an issue on their site.

https://www.cummins.com/engines/repower

Perhaps reach out to them directly or your state.

There's a guy on YouYube that documented his install of that engine in his D1 Maybe check him out and see how he did it.
Regarding that shop...
Maybe the 110 install was on a pre-ODB2 trucks they had no emissions to worry about?
