So my Perentie Ambulance has a cracked block. I bought an upgraded version, the Isuzu 4BD1T and asked British Rover Repair in Atlanta to install it. They can't seem to make it work even though its a common conversion in Australia. So I'm stuck. Getting another 4BD1 from Australia is an option, but those engines are in high demand and not really available. And apparently no one has a spare 4BD1 in the USA . So what about upgrading to another diesel. Any recommendations?

I think the first question you likely already asked the shop was what's wrong with the replacement and why can't the shop get it to work?
Is it something that a person with the correct skill set could overcome and get up and running for you?

The engine should go in fine. All they should need to do is move over the clutch, flywheel and flywheel housing and maybe some front drive items. Maybe find another shop that knows how to do mechanics and not just parts swappers.

Once you get it going change over to a decent turbo and you will never look back.

What do you mean by an upgraded version? Not a new 4bd1t from china???
Or is it a truck motor?

Not wanting to make it happen is an excuse for not interested in the job.
aka it’s beyond their abilities.
My local shop here in mass converted a FC101 to Isuzu non turbo, added a turbo and mated it to the stock four speed box.

Everyone above gets it right. I think it's pretty clear that British Rover Repair is out of their depth and making excuses as to why this isn't doable, when it definitely is. This may be a situation where you need to go to a diesel-specific shop.

Even here in Los Angeles my Perentie has two different shops she goes to, Rover specific for general service, and Diesel specific for engine tuning/support. I've been to five rover "specialists" who were baffled by seeing an Isuzu engine in the truck and wrung their hands of wanting to touch it. After that I found a diesel shop that specializes in Isuzu's and it made it so much easier. Since ATL is a hub for trucking I'm sure there are some heavy hitting diesel mechanics/shops that can set you straight - I'd inquire to them.

Just a thought. Look in your area for a Isuzu diesel truck place. Probably at the same shop that sells and services Freightliners
