We've been getting these questions a lot lately: What will a diesel swap cost, and can you do one? We've put together a playlist to help you in planning your project!

Why it's $10k:

  • 6BT is ~$2000 + $1500 for basic rebuild (head, pistons, rings & bearings).

  • Adapter plate, flywheel and starter is ~$2000.  
  • Shift controller is ~$600.
  • Alignment fluids, fittings, hoses, machining is ~$500.  
  • DG shop rate is $65/hr at an estimate of 70 hours.
  • Don't forget shipping + taxes!
