This big single turbocharger install kit from WCFab for 2001-2004 Chevy Silverado 2500 / 3500 HD trucks contains what you need to swap from your stock IHI style turbo to a larger frame Borg Warner S400 style setup on a 6.6L LB7 Duramax diesel engine.

Key Features

  • Includes our upgraded high flow 3" fabricated billet y-bridge kit which replaces the restrictive stock upper intake manifold to finish off the air flow path into the engine and allow for maximum horsepower and efficiency gains.
  • A variety of popular turbo size options (sold separately) mount to a T4 fabricated steel pedestal with spacer which is compatible with our 2" high flow stainless steel up pipes.
  • Included high temp ceramic coated turbo downpipe connects to your existing exhaust front pipe V-Band clamp.
  • This simplifies installation and requires NO cutting or modification to your exhaust system.
  • You may be required to ship a separately supplied turbo to us in advance for mock-up to build your kit.
  • Includes Driver Side Transmission Dipstick Tube, making installing the down pipe easier.

Fitment

Fits 2001-2004 Chevrolet Silverado 2500 HD / Chevrolet Silverado 3500 HD / GMC Sierra 2500 HD / GMC Sierra 3500 HD equipped with the 6.6L LB7 Duramax Diesel engine.
