Cummins still makes the 4 cylinder B-series engine (i.e. the "4BT"). It's now a 4.5L engine--it went from 3.9L to 4.5L when the 6 cylinder engine went from 5.9L to 6.7L. It's no longer sold for on-highway in the US, but it is sold for off-highway in the US an on-highway in Europe, Brazil, & other places.
Cummins also makes a 3.3L 3 cylinder B series engine. I know a guy who put one in a Jeep.
