This 1988 Mustang called Coalstang was built by Darcy Hanlan. In the engine bay sits a 5.9 L 6BT turbo diesel inline-six connected to a 47RH four-speed automatic transmission both taken from a 1994 Dodge 2500 2WD. The engine features stock injectors, HY35 turbocharger, 1994 P-pump, shortened oil pan, and 5k rpm governor spring kit. He installed the engine by lowering the steering rack about 1.5 inches and notching/reinforcing the crossmember. The car sits at a little over 3,550 lb with driver.

Probably gets 35mpg at 100mph. Will it do a burn out? Amazing it fits and the suspension holds the beast. Roadkill did an old Cady this way and it was a blast.
