    Hello all this is my first post, I had my 53 block crack beyond repair at 188k miles. I have found a 2001 freight liner 24 valve non-53 block for 2k. I was wondering if it would still work? The guy that has it doesn’t seem to know everything about diesels (neither do I) so I’m at a loss. Would...

    Which trans would be most reliable/longest lasting behind a 600hp cummins. With these autos would i be able to get 150k-175k miles at this kind of HP or am i looking at a rebuild every 50k. Trying to decide between auto and manual for my swap.
  6. 07.5 - 09 3rd Gen 6.7L Powertrain
    Ok, so I have a 2008 dodge ram 2500 set 6.7 and got rid of the 68rfe and put in the g56. I about have everything squared away, even wired the nuetral safety wire to ground, only the truck wont start. I haven't flashed the ecm yet because I figured I could drive it to the dealer to have them do...
  7. 12v Conversion Build Threads With Shop Talk
    Started a new job in a new city in California. Do to the smog laws here I was told they had to get rid of one of their trucks. Before they did they pulled 24v 5.9l and what I believe is an Allison 1000 transmission (both remanufactured). I found a truck for it over the weekend. The wiring...

    So I have a 1978 K30 that I was planning on swapping a 5.9 into. I know this is a pretty common swap and have no problems with the physical swapping or compatibility just had a question about the Gen 1 vs Gen 2 Cummins. In my area I am having a really hard time finding a gen 1 5.9 to use for the...

    One of our 06 5.9s hit a deer the other week and it looks like its going to be written off. Planning on buying it back as the truck is important to our family. I have a 1991.0 12 valve and I always LOVED the he351 on the late CR 5.9 and would love to have it on my 12 valve. I am assuming I would...

    Has anyone used this transmission behind a hoped up Cummins. I can't imagine breaking any hard parts. The question is how much torque will it take before the clutches start to slip. The 12v would be making around 600hp.
  11. General Diesel Discussion
    With the 5.9/6.7 and maybe the 8.3 all having very similar setups, an electric motor with ecu harness satisfying connections to swap into the millions of Cummins setups in the world would be a really smart idea for Cummins or a motor supplier. Anyone agree? I know my excavator, wheel loader, and...

    Hey y’all, I’m curious and I’m sure others out there are as well. I love my exhaust brake and the very loud whistle on a cold start EB on start up. However, I also love the 2nd/3rd Gen swap sound just in general on a 4th Gen. Is there a happy middle ground out there? Would an S3xx on a 3rd Gen...

    My Truck = 94 Ram 3500 "B-Engine" 94 12val 5.9 CTD Tow Co. Destroyed Tranny. Stock 47rh Automatic Will this bolt up? 5 speed standard transmission out of a 2001 Ram 2500 CTD. Also does anyone know if this transmission is good for Stage 100 HP with a FAS...
  14. 3rd Gen. Non-Powertrain
    hey guys i have a no crank at the key situation. i swapped an entire system from one truck to the other i beleive i have everything correct with the electrical, it will crank at the signal wire directly so the starter is good, heres what i have tried: used hptuners to disable skimkey to ensure...
  15. 98.5-02 Non-Powertrain
    So I recently bought a 2001 Cummins, it came with leather power seats in it but I’m now realizing they’re not factory, so no heat switches or anything, I’m not even sure if they’re the heated version of them. That’s why I’m here, wondering how to tell if they are the heated version as I’m pretty...
  16. 2010-2012 Powertrain
    I'm looking into manual swap options once my 68RFE bites the dust. I'm leaning towards the NV5600 but need more clarification on a few items to be able to make a decision on the direction I want to go. Will the G56 Adapter Plate work for the NV5600? Will the 68RFE Tcase physically bolt to the...

    I have a 1988 chevy k3500 4x4 with the 454 big block in it. I wanted to do a 12 valve swap into it with NV4500. What are some of the issues that I have to worry about? Like oil pan clearance, new engine mounts etc.
  18. General Diesel Discussion
    How much power are you making and how many miles have you had that hp. Just wondering what kind of engine life can be expected from a 500hp 12v cummins. Originally was thinking of a dt466 swap but if the Cummins can make that power and still last 200k miles and just need some bearings and rings...
  19. 89-93 Powertrain
    So I’m looking at buying a 93 first gen with the A518/46RH I want to know if I can swap a 48RE into it, the 48 I’d want to use is going to have a full manual valve body and a gated shifter Edit: I know it won’t bolt right up, I’d probably have to change the adapter plate, flex plate starter and...
  20. 3rd Gen. Powertrain
    Hey all, I am looking for a simple yes or no answer and I have tried looking everywhere to no avail. Since the late 3rd gen 1500 Mega Cab Hemi (07) sits on a 2500 frame, will the FRAME engine mount also accept the 24v 5.9 Cummins?
