BD’s Compound Add-A-Turbo Kit for the Chevy Duramax
LML is a great upgrade for drivers wanting a reliable 500hp truck but still
keep stock turbo spool, the ability to tow heavy loads, and, maintain safe
EGT’s. The factory Variable Geometry Turbo (VGT) retains the use of the stock
exhaust brake and rapid turbo spool while the addition of the BorgWarner S475
turbo supplies the extra air needed for higher performance. The clean install
retains an enclosed cold air intake, dual aluminum coolant tank/overflow
tank, and, the passenger side battery in the engine bay. The kit includes a
BD passenger side up-pipe, PCV system, rotomolded MAF/humidity sensor intake,
5-inch air filter, 3-inch CNC ported hot pipe, O-ring sealed v-bands,
silicone molded coolant lines, 4-inch downpipe that does not require cutting
of the fender liner, and, everything needed for an easy install.
