Mar 5, 2012 · I still run a VT-903 in my K100. What you've got is a VTA-903, and that 650HP is already double what I'm running, at the stock 290HP. Your VTA is running an intercooler, oil cooler, and aftercooler that my truck doesn't have, since they were military spec (I believe I just have a small oil cooling cyinder).
Turning up a 903 - TruckersReport
Nov 23, 2010 · The engine was rebuilt less than 25,000 miles ago, so my only concern with turning it up is the driveline.

Cummins ISX High Oil Temp! - TruckersReport
