Welcome to The Mason-Dixon Turbo Diesel Club

Mason-Dixon TDC is a chapter of TDR (Turbo Diesel Register), known all 'round the world for its online Dodge Cummins Turbo Diesel community. The club was established in 2001 to organize the local community of Dodge/Cummins diesel pickup truck enthusiasts. MDTDC later extended its charter to include other light-duty diesel vehicles, including popular light truck diesels such as the Ford Power Stroke and the Chevy/GM Duramax. MDTDC currently encompasses a six state area commonly known as the Mid Atlantic; it includes MD, PA, VA, WV, DE and NJ. We encourage all car and light truck diesel enthusiasts who reside in these states to join our chapter and become part of this growing local diesel enthusiast club.

GM/Duramax GM has had a long history with trucks and diesels. Alas, their reputation with their early years of diesel pickups was far from stellar; however, the 6.2L and 6.5L diesels were known to run for many years. Several versions of the 6.6L Duramax have been available: LB7, LLY, LLY (2006), the hot rod LBZ, and the LMM.

  • 1978—GM introduces the Olds V8 diesel engine in 1/2-ton pickups. Poor performance and reliability caused early cancellation of these engines.
  • 1982—Chevy's 6.2L diesel becomes available in most full-size light trucks.
  • 1990—The 6.5L turbo diesel replaces the 6.2L diesel in 1991.
  • 2000—The 6.6L Duramax is introduced, although the 6.5L continues to be supplied in other products.
