. . .repair and upgrade the Chevrolet and GMC light-duty trucks
Some might interpret a swap as an upgrade.

Between the D-max and a Cummins, what are the realistic, usable power capabilites? Not for racing, but pulling loads easily and efficiently. I have seen 800hp injectors for the Cummins, but that does not mean it should be done. If the choice for a swap is a crate d-max and a crate 6BT, why (other than GM product) would someone choose one over the other? I have seen that some maintenance parts for the Cummins are quite expensive, but injectors seem to be an issue with the d-max. I am not preparing to do any swap of any time right now, just curious.

Incedently, it was asked if someone wanted a cummins, why not buy a Dodge. I like my Suburban, Dodge does not make one.
