Cummins 6BT is doable, but a little too big/heavy. Then looked at Cummins 4BT, but they're very loud and getting harder to find. The 4BT does have huge aftermarket support as most 6BT go fast goodies work on the 4BT.

The Isuzu 4BD1t is less favored in the diesel swap world, but I believe there are many times more units available in the world. It's quieter, and the IP supports close about 250hp turned all the way up. Rebuild kits are cheap, ~$900. It's very similar to the 4BT in displacement and size and although rare, adapters are available.

I have a different turbo, charged air cooler (intercooler) and hoping for 200HP. This isn't a typical ecomodder build as I'm not primarily going for economy. When I made this plan, I was making biodiesel at home. Now it's just a fun project. I still buy B99, but stopped making it.
