Hi all- I have a 90 Dodge Cummins that I want to know if I can swap with 01 industrial 12 valve? I have read a few things that say they are not very conversion friendly but can still be done with some modifications. Anyone have any info or done one of these before?

 

There are many variables on an "industrial" 12V. Typically the injection pumps are less favorable than an automotive 180-215hp style. The basic block and rotating assembly, head, valves etc will be similar to a later 12 valve. Anything wrong with your '90?

 

My 90 had a bad cylinder so it got torn down. In between this time I had bought a new cylinder head, had it machined, beehive springs, machined rockers. Got a Hamilton Cam, FASS fuel sytem, 3 piece exhaust manifold and a bunch of other parts. The 90 had a Banks kit on it with the exhaust so that will go back on. This industrial cummins has maybe 120 hours on it - oil still clean. Really couldnt pass it up as opposed to having the other block machined and gone through (stupid expensive). So thats where its at and I am hoping this will work. It will have to or they gonna have to bury me with the truck lol.

 

Shouldn't have any issues if you are taking it down to the block and rotating assembly, though you may want to investigate what injectors are in the industrial motor. Might have had a different spray angle ? which could mean different combustion bowl? Not sure how many options there were.
What are your plans for injectors/pump?

 

From which motor? I think I'm reusing the pump off the 90 but I think Im getting some bigger injectors. At least I think that's what the plan is.

 

Best guess is your VE pump is the easiest option. If you were running stock spray angle (155*) injectors from a non-IC, they might spray outside the bowl with a motor designed for 145* spray.

Again no idea what the industrial motor will come with. If you get some numbers off the motor and injector pump might be able to tell something before hand. Bottom line, match spray angle to the piston bowl.

Some care should be taken to check piston to valve clearance on assembly, just in case.

Ps I didn't list some of the external differences, thing like oil pickup tube and pan, water nipples, etc will be different but you will have all that on the old motor.

 

I will see what I can find by model number of pump. This is how it looked when we started taking it down to switch parts- how could I pass that up? There must be no miles hardly on it. Appreciate the knowledge. I'm sure I'll have more questions lol.

 

Any chance the pistons will be different between these motors?

 

It's very possible. They are matched to the injector spray angle, and perhaps other factors. As far as 6BT engines for dodge, 155° on the non-IC. 145° for intercooled (91.5+).

 

That would call for the thicker head gasket correct .60?
