Help with engine repower

I need to repower my engine because of the CARB regulation and am looking for company/vendor that can do it. It is a 2004 Freighliner Columbia with a Mercedes engine switch to Cummins 12 valve or Detriot DD 13. I am having trouble finding someone in the Southern California area that will do the repower and I have until the end of the year before I am non compliant.

 

Repower will cost you way more than buying a compliant truck.. between engine and dpf def systems and wiring I’d be surprised if you could do it for less than 50 k

 

Dude, many of us have stated in your other thread that a 12 valve Cummins WILL NOT WORK!

Its a 5.9L engine. It is grossly inadequate for anything above a 1 ton pickup truck.

 

Seriously, that repower will cost you more than that truck is worth. And you need to research the motors that you are talking about.

 

Wait, he's talking about an actual 12 valve?? Wow. I managed to get mine hopped up to 1,350 lbs torque, and it would hit 2,000 degrees EGT in just the quarter mile. Not sure how good it would be for pulling 80k. Fun to drive, though. HE351cw/HT4C and 80 pounds boost.

 

Fun to drive, I bet it is! Did you do anything to the bottom end, or just stud and fire-ring the top?

Who built your engine? Not sure if any of the shops here in Corpus are any good or if I need to take mine out of town.

 

I didn't even have to do fire rings. As long as you watch your drive pressure and timing, it takes a lot to blow a head gasket. I was only running 18.5 degrees of timing. The usual "free pump mods" - ground 3/8 off AFC foot, remove fuel plate, etc. Governor springs, Hamilton 165 beehives, billet pushrods, titanium keepers, head studs. 7x12 injectors from before Contagious Diesel got ran off Cumminsforum. The stock bottom end is good for 1,000 horsepower. This was a 1997 215 engine I put in a 1993 Chevy Silverado 4-door dually. I built a 47rh for it, and controlled OD and lockup with Hobbs switches running off the governor tap. 241DHD transfer case, and the rest was Chevy. I can't even remember all the stuff I did to that truck, but the list was long and distinguished.

As long as you have a rocker that can handle that engine, they're easy to build. And extra set of hands to help set the crank and head would be nice, but you can put a 12 valve together in eight hours by yourself. Couple days if it's your first time.

Here's one of my runs back when it had a single turbo and 359hp/831tq. Truck has a W/T grille, because I couldn't fit the Dodge intercooler with the Silverado grille and headlights. I almost blew an intercooler boot clear in half right before the 1/8th. I was doing 79mph at the 1/8th, and finished the run at 71mph. Still beat the truck next to me by 2.5 seconds. The exhaust pointing up is just for dragstrip purposes. Otherwise the black smoke "smokes" the starting lasers and screws up everyone's times on the timesheet.

I can't believe it's already been ten years. *sniffle

 

That thing scoots pretty good. It's a shame you couldn't stay in it all the way, but that's what happens when something breaks.
