. I’ve been chatting you up on your FB thread. Didn’t realize who it was.

That’s more my speed…love me some Cummins beige. Makes spotting oil leaks that much easier.
How many do you want? Lol.
im not talking parts, im talking a whole kit like used to be available that included everything needed. I think Duiser (Dustin) used to sell it.
Name one that has all parts needed in one kit. I don’t find any. Just different places selling different pieces. So, yeah, name one if you can.

No there is no Commonrail kit on the market..but everything we are doing / designing is getting documented and all parts are getting modeled in CAD so a CR kit/conversion parts can be made available.
All of the parts on the market right now through Dustin/Pip, Joel, etc are all for the 12V 6BT. Those parts do not work with a Commonrail.

The black Cummins is to hide the rust prevention accessories ports

Hoping the Commonrail keeps more oil on the inside than the 12V’s

Safety 3rd!I love the hippies Jamaican safety shoes
There are small differences to installing a CR 5.9/6.7 or a VP44 24 valve, but nothing major.

There are quite a few major differences. One cannot buy any of the parts on the market already and then make them work for a commonrail going into an 80.
6BT engine mounts are in the middle of the block, CR has 2 mount locations on the block, but the center ones are partially covered by the ECU. So engine mounts that work for the CR and the 80 need to be fabricated.
The PS pump on the CR in its stock location interferes with the 80 steering box, so that needs to find a new home.
Valve cover clearance, #6 injector clearance, fan clearance are all items that need to be addressed.
Everyone has their own approach.
I do it like this-
-Remote mount PCM
-Custom machined valve cover clears firewall and removes easily
-Punch a hole (knockout punch) for #6 injector line clearance then install rubber plug.
-Move steering pump up
-Run pre-2002 accessories
-Install same upper radiator hose used with 12 valve on CR Dodge waterneck using heat gun (1.5 VS 1.75").
-Use a 2nd gen (98-02) 24 valve exhaust manifold
-The intake elbow is different for the 24V/CR VS the 12 valves. The CR version is on the shelf.
I may do the power steering a different way on the commonrails going forward. With the right timing housing I can run a new style PS pump and tach drive that works really well in an 80. I haven't tried it, but I like the idea better than running the belt drive pump.

None easily accessible.
Another thing- you need to flip the fuel return to the front of the head.
This is exactly what I want to do. My daily is an '06 cummins and I've been looking for the same engine to stab in my 80. I might have missed it but what transmission are you going with?

I already have the NV4500 all built as I was running that behind the 6BT. So sticking with that setup. Been slowing collecting the parts we need to make the commonrail run whilst @Delta VS has been working on the hard engineering parts.
Rebuilt and modified CP3 injection pump, Fluidampr harmonic balancer, rebuilt and slightly larger injectors, new Cross over tubes, stand-alone harnesses, new turbo (modified HE351) all new Cummins sensors, and cooling parts. Probably more that I am forgetting…but there is no point putting old parts on a brand new motor!
Awesome! Do you have any notes on the wiring mods you did to the painless harness? And I am excited to hear there might be swap parts available soon.
What you're doing to the engine sounds very similar to what mods are on my truck currently (dual disk clutch, 90 horse injectors, mod'd cp3, head studs, and a few tunes) and that setup will be an absolute monster in an 80
