Trade in your 6.7L’s finicky VGT for a proven al­ter­na­tive

IF YOU HAD NO CHOICE BUT TO RE­PLACE A FAC­TORY COM­PO­NENT ON YOUR TRUCK that failed pre­ma­turely, would you opt for an OEM re­place­ment that’s likely to meet the same, un­timely fate, or would you spring for a more reliable af­ter­mar­ket al­ter­na­tive? How about if a guar­an­teed per­for­mance gain was on the table and the “forced” up­grade could es­sen­tially be had for the same cost?

Af­ter ex­pe­ri­enc­ing a tur­bocharger fail­ure at just 114,000 miles, the owner of this 6.7L Cum­mins-pow­ered ’14 Ram 2500 wanted no part of giv­ing an­other OEM unit a try. In­stead, BD Diesel’s Rum­ble B Turbo Kit piqued his in­ter­est. The BD sys­tem re­places the fail­ure-prone fac­tory vari­able-ge­om­e­try turbo with a proven fixed-ge­om­e­try unit, comes with a high-flow ex­haust man­i­fold, and even in­cludes a cold-air in­take assem­bly.

With a time-tested fixed-ge­om­e­try Borg­warner turbo in the mix, the 6.7L Cum­mins sees less drive pres­sure (sav­ing the head gas­ket), a re­duc­tion in peak ex­haust gas tem­per­a­ture (eas­ier on the en­gine), and an in­crease in boost (more power). Tag along as we in­stall the BD Diesel sys­tem and spot­light the fun­da­men­tal parts that make this com­mon­sense turbo swap worth­while.
