17 hours ago17 hr New to this forum, but not the cummins forum. I bought this truck a month ago, turbo bearings are shot.I bought a Borg Warner K27 turbo. Truck is set up with a 4 inch down pipe with an HX40 4 3/8" Flange. I need an adapter to go from 3" inch ( stock size ) up to the 4 3/8" flange. I've called several diesel specialty shops. No luck.
