I found a 2003 duramax that was wrecked, but the engine,transmission, interior and drivetrain. well they want 6500 for it, Im not real sure if this is a good price. anyways I am contemplating a duramax swap into my 2004 1/2 ton z71. My semi plan is to get get a two inch body lift to clear engine/tranny (mainly tranny).After I make engine mounts then I can start swapping, changing all the electronics under the hood and behind the dash, then swap over the fuel tank and fuel delivery system.After all that I would swap over the hydroboost brakes, install intercooler, probably change out transfer cases and get a custom driveshaft for that t-case to my front diff, im guessing touch ups are next. Im 100% positive that I am missing some key steps and I would like some opinions so I can hopefully make this swap work out alot better.

P.S. a 1/2 ton NBS would be sick with a duramax, almost forgot that i have some 1ton torsion bars that i could put in to support the weight, but I will leave the suspension alone unless its in the way or not strong enough to support that behemoth of a engine/tranny combo.

save that $6500 to buy a complete drivable duramax to be honest

Have you ever seen prices for a running Dmax or Allison?

best bet buy a running D-Max, 6500 is a deal for full drivetrain and interior the wiring is ungodly nothing will line up and i mean nothing (fuel tank/lines, guages and computers) save the cash and buy a whole truck or find one that has all cosmetic damage get the cab repainted and swap your sheet metal on to it

not to mention if you did get everything to fit the dmax would trash the half ton diffirentials pretty quick. Are the axles good on the donor? i say its aloooot of work thats not worth it unless its something you could not get similar from the factory.
