BD Diesel Performance Single & Twin Turbo Kits

Featuring Borg Warner’s extended tip compressor wheel and BD exclusive dual-volute turbine housing, the Super B Special can deliver enough air for 525 rear wheel horsepower on diesel only, and is a bolt-in replacement for the stock turbo.

Plus, the adjustable waste gate with a high temperature resistant Nomex diaphragm and heavier spring keeps the bypass valve closed, raising boost levels for increased performance and helping to prevent waste gate “creep”.

1989-1993 Cummins 5.9 engines have a variety of large turbine housings that all result in a large turbo lag before boost is developed. The above years will benefit by changing to a 16 sq cm housing to a non-waste gated turbine housing part #1045910 on stock or engines that have had high flow injectors installed

1994-1999 stock engines have the 12 sq cm w/g hsg that can be quite restrictive when the power is increased above 300 flywheel HP and results in high exhaust temperature.

2001 automatic transmission equipped engines have a 9 or 10 sq cm hsg that is too restrictive for a high power increase (beyond the 300 hp)

2003 and 04 BD twin turbo's include an adapter so the turbo mount exhaust brake can bolt up; later models require a remote mount exhaust brake. 2003-04 Engines that have any more than a 100 hp increase will cause the stock turbo to over speed, surge and fail.

The ultimate “bolt-on” for the Dodge Ram! BD’s twin turbo's for the Dodge 5.9 liter Cummins engine can develop between 350 to 700 rear wheel horsepower (rwhp) with adequate fueling (diesel only) while remaining responsive and durable enough for street and towing applications. Not only do these kits deliver impressive horsepower and torque increases, they look great and sound incredible!

BD twin turbo kit features a pair of stage-compounded AirWerks S300 turbochargers equipped with extended tip compressor wheels to keep air flow high, and exhaust gas temperature (EGT) low. The kit’s high-pressure turbo provides quick, low-rpm response, which is then compounded by the low-pressure turbo for a broad power curve across the engine’s rpm range.

Plus, the high-pressure dual volute waste gated turbo in this kit is the same used in the BD twin turbo kit, making it easy to step up to twin-turbo power when you’re ready.

For competition applications, even higher horsepower (675 plus) and boost pressure (100 psi) can be obtained-- however a lot of fuel and a shot of nitrous to overcome the inefficiencies of the stock intercooler. 2003-current trucks can also benefit from BD’s new Cool-It intercooler; applications for earlier trucks are currently in the works.

The BD twin turbo kit comes complete with a stainless steel X-Intake, flow-matched exhaust and intake piping and all necessary heat shields—plus, ’03-06 applications come with our new three-piece Pulse exhaust manifold. Installation allows for the stock oil cooler to be left in its place.
