The engine room was expanded and reinforced by the droid crew to allow for a complex propulsion system. The standard on a Barloz, the Nova Quad-D Drive system and the Mason-Branger ionization reactor, was replaced by a complex array of systems. Original Chedak Communications system in the stock model was one of the first systems to be replaced, and the Pax Hustana Sensor system was outdated. The standard Phoah-Kingsmeyer Screen Control and Shield Projector Systems was taken out and upgraded to a more efficient dual system.
