Serious Power for Serious Work

If you're running an early ISX Cummins and looking for a dependable power boost, the BD Diesel S478 T6 Turbo Upgrade is built with exactly that in mind. Designed to fit 1998 to 2002 ISX engines using the 1048008 exhaust manifold, this turbo delivers reliable performance and better pulling power without overcomplicating the setup. With a 78.23mm inducer and an extended tip 106.20mm exducer compressor wheel that stretches out to 112.96mm, it’s designed to move a serious volume of air. That means stronger acceleration under load, better mid-range response, and the kind of torque that heavy haulers and working trucks need every day.

Built to Last and Designed to Pull

BD didn’t just go big on performance—they also focused on reliability. This turbo features a 270-degree thrust bearing and is VSR high-speed balanced to ensure smooth operation and long-term durability. The dual volute T6 flange with a 1.32 A/R housing allows for better exhaust flow and reduced backpressure, helping the engine run cooler and more efficiently. Fewer moving parts mean less that can go wrong down the line, which translates to fewer breakdowns and lower maintenance costs over the life of the turbo. Whether you’re pulling steep grades, hauling long distances, or simply need a reliable upgrade to keep your truck productive, this turbo is made to get the job done without cutting corners. Keep in mind it meets federal EPA requirements, but it’s not approved for use on California-registered vehicles.
