Need some recommendations

So I’ve got this 99 wrangler that I’d like to swap with a smaller Diesel engine, I’m looking for something with very few sensors and other electrical components if possible. I just need maximum power with lightest weight/ smallest size. Not really sure where to look. Would prefer an engine that I can mod to. Any suggestions would be appreciated

Your best bet is a 4BT Cummins. Easy to work on, extremely reliable, and readily available. Lots of parts in common with the 6BT that the Dodge boys use.

Cummins is also putting out a crate TD engine now, specifically marketed toward Jeep swaps.
