S400 (62 over S475) Twin (Compound) Turbo Kit Fits 1994 - 1998 Twin Turbos for Dodge Cummins
This compound kit is the most unique and innovative Twin Turbo Kit available today, with features like:
- Direct bolt-on application, no cutting or fabrication needed.
- High Flow 3-Piece Exhaust Manifold included in kit.
- Largest air filter on the market.
- Our kits now come with two separate oil drain lines, except for 12V engines that have only one oil drain port.
- Comes with a 4” Exhaust Downpipe for 1994-2002 trucks.
- Low pressure charge pipe is silicone with Kevlar/Nomex liner (which is easier to fit than a steel tube, and extremely strong). Silicone tubing uses fewer clamps and has better flow/insulation characteristics than steel.
- High pressure charge pipe is strong chrome plated aluminum.
- Small turbo has a 150% greater wastegate capacity.
- Cast hot pipe, has external wastegate port already built-in, which won’t crack like welded pipes do.
- Flexible Steel Braided Oil Supply lines.
- Flexible Stainless Steel Oil Drain lines.
- Polished Diesel Power Source (small) turbocharger.
- S475 Borg Warner (S400 with 75mm compressor wheel) as a large turbocharger.
- Support bracket for Lower (large) Turbo.
- Adjustable boost pressure.
- Tons of other upgrade options (Upgrade options include increasing the S475 turbo up to an S480 or S483 and the DPS 62mm turbo to a 64mm, or Turbine Wheel Sizes Call for details).
Our kits now come with two separate oil drain lines (except for 12V engines that only have one oil drain port).
Diesel Power Source, Twin/Compound S475 Twin Turbo Kit, performs excellent when Racing, Towing, or Sled Pulling, but is very mild mannered. SPOOL UP IS IDENTICAL TO STOCK, while raising airflow significantly. You'll be amazed at the spool up, and driveability from such a high performance kit. **SPOOL UP SIMILAR TO STOCK TURBO.
EGT's are typically reduced by 300-500 degrees, over a single turbocharger.
Boost pressure will typically exceed drive pressure, which can't typically be done with a single turbocharger (with single turbos, typically drive pressure is nearly double boost pressure).
Horsepower, and torque are increased throughout the entire RPM band, and significantly increased in mid and upper range.
Specifically tuned for 350 to 800 horsepower applications.
This Twin/Compound Turbo Kit was designed on cutting edge CAD/CAM Software, using CFD (Computational Fluid Dynamics) Testing. You will not find a more high tech kit on the market today. Everything fits like it was built from the factory to be there.

Head Stud Recommendations:
On 3rd Gen 5.9L trucks, head studs are highly recommended for boost pressures that are over 55 psi, and fire rings are recommended for boost pressures that are over 65 psi.
On 2nd Gen trucks and 6.7 L Trucks (3rd and 4th gen), head studs are highly recommended for boost pressures that are over 48 psi, and fire rings are recommended for boost pressures that are over 55 psi.
All of our Compound Turbo systems are capable of over more than 55 psi, but are adjustable depending on truck.
**For 1st gen trucks, intercooler hose modifications may be necessary
** On trucks with automatic transmissions, some trucks require relocation of the transmission oil cooler on the side of the engine block, but not all 2nd gen trucks require this.
