fummins swap and need help!
 

so i got a 95 powerstroke and i just bought a 89 12valve with 80k ORIGINAL miles. its all tore apart getting new gaskets and possibly new rings since i have it all apart. but anyways im getting ready to pull my motor here in couple weeks but i ran into a dilemma. im runnin a updated e40d tranny, and i was looking at the adapter plates online, and wasnt sure but am i able to use my flex plate? or do i have to order the new flex plate with the new adapter plate? thanks for the help and any extra advice on the swap will be much appreciated!

I personally used all dodge drive train and the money I saved from having to buy adapter plates I was able to use elsewhere on my conversion

What he said. Save yourself the headaches and use a dodge transmission and tcase if its going to be 4wd. Plus for the cost of the adaptor plates plus parts needed to match like a flexplate most likely. your better off just buying a dodge tranny. BTW VE is the way to go!!!

the ve and the p pump both have their good qualities the p pump is easier to turn if you want to longevity I have to say ve pump is probably better i have both and my ve has 400k on it p pump has 165 the p pump is more finicky about lift pumps this is more personal preference that mechanical superiority

I personally don't want the huge hp because it takes fuel to make hp and I want the diesels economy


I pull a 40ft gooseneck with a stock 90 dodge cummins 5 speed ve pump and put a 20k track hoe on it and it does just fine don't want to go 70 but with that much load you don't want to any way

ok its been awhile but i got the whole motor all tore apart all cleaned up and got new bearings, rings and just waiting on getting injectors pop tested. but i need some advice on what tranny setup i should use. i was thinking of running a 47re and the 241 transfercase. but i wasnt sure about what computer i would need to get for the transmission. or would i be better off buying the nv4500 and transfer case? all the input is appreciated!

Ok so I just got myself the nv4500 with transfer case for the swap, and now got few motor questions, my plan was to do Denny t Stage 2 fuel pin, 3200 gov spring, 60# valve springs, and swap stock turbo for the hx35. For now I'm gonna run stock injectors but eventually want to get bigger. But I was curious what a guess would be on my hp and torque with this set up? And I want to have my truck fast but also building it to tow my trailer occasionally

That sounds like a good start. I have a bd pin which is compairable to the denny t i forgot what stage though. I also have the 3200 gov. Spring as well as an hx35 with a welded wastegate. As for hp wise i have no idea... But if you do those mods you should look info tuning your pump, i still need to do that but tuning your pump should add alot of oomphf to your truck as well. Valve springs are another necesety if you plan on going more hp or higher rpms.
Have you done the killer dowl pin? If not get that done as well.

Ya I did the kdp fix when I re built bottom end of motor, and ill probably tune the pump. I was thinking of turnin the screw in about 2 turns.

use a 47rh tranny have it built up for your needs the 47rh is a non computerized tranny it will do you fine

So I got the front clip of truck all tore down to the frame rails and ready to pull motor. But I can figure out what exactly of wiring harness I need to save. And I'm using the nv4500 tranny. And also what computer is it I need to save?

if your using a rotory ve or a p-pumped motor with a nv4500 you dont need any computer..... just cranking hot and key on... for the starter and fuel shut off

But what bout the lights and everything else on the truck? Is that just run off of the fuse box? Or and I get rid of the entire wire harness and just leave fuse box?

Keep stock Chevy fuse box and electronics, just tap 12volt sources needed for 12v...

use your stock temp oil press senders no sure of he tach for that truck the superduty I do know

now remember the oil pressure sender is a 7 lb trigger it will read in the middle if you are over 7lbs pressure you also need a manual oil press gauge

if you are using a 12v ve or p pump you need 12v the p pump used 2 12v wires a pull hold wire-+f4 the nv4500 has only one wire to it and that is for the reverse lights

I have done a couple conversions, while the above is true an oil pressure reading is oil pressure right?... If you are going analog then might as well do a pillar with boost and egt, there cheaper in kits.. If your looking to make this thing an easy swap, use stock Chevy sensors and bushings from ace hardware to adapt the Chevy sensors. They are expensive, but would also recommend head studs, so anything you upgrade later, you will have no fears

It's NOT a Chevy :s:

a ford sensor is different if you have at least 7psi it will read in the middle of the gauge

Ok so I get my upper gasket set and my new main bearings and rings Friday so motor will be all put together Saturday! But I need help figuring out what pedal assembly will fit my truck. And I need to get the clutch pedal, brake pedal and gas pedal

love to have a 2005 fummins... sickness

So I was lookin at the transmission and was curious bout it and typed the casting numbers into computer and came up the transmission is out of a Chevy but it is the nv4500, does anyone know if the input shaft is the same as the dodge input shaft?? Or do I need to buy new input shaft?

The Cummins NV4500 input is fatter and possibly longer. What year is the trans? The early GM ones (91-93) have different ratios, and as a result, the cummins input may not be compatible.

Hey it's been awhile since I've been able to be on here, I found out I can swap out to 1 1/4" input shaft. I also get my my head back from machine shop from gettin valves lapped and the top decked so they will all be perfectly same hight. Then I will have rest of motor together. But I was wondering bout the nv 4500 when I set it in the truck, will I have issues with it touching the under side of my truck or should it clear everything?

i skipped over some of your build comments and i haven't been on here for a while but...(1)for your wire harness DONT cut anything on the wire harness until you have the swap done. Get the engine in and get the engine running and hook up every wire that you need, Headlights, any stock sensors, wires for heater box and wires for internal power. Figure those out then what isn't left unwrap the harness and trace back the wires to the plug in the cab and cut them off. I found this to be the easiest way of shaving my harness and not to brag but compared to other swaps my engine bay looks clean and birds nest free which is awesome. (2) for the NV hitting the bottom of your floor its all about your transmission cross member that will determine how high or low your trans sits. Keep in mind that you want the engine to sit as level as possible because of where the oil pickup tube is. I made my own crossmember idk if you plan on utilizing the factory one but i had to cut mine out so i had no other option. Sounds like your engine is coming together awesome. I wish i did the same to mine but after pulling the engine twice already i have no ambition to do it again lol plus its too much fun to drive and hopefully it'll be plowing soon... OH and plan on saving money to get the driveshafts built... my rear was 300 and thats with having the stock one just lengthened with a new yoke welded on.... my front one 640 custom built from transfer case to front rear. :argh:

so i bought a tranny i thought would work but ended up not being able to use it, but the transfer case i cant figure out if its usable. im planning on buying a new nv4500 but i got a np241 transfer case, it had a 32 spline input on it and i read that you can swap the output shaft on the transmission to adapt the transfer case. i also read though that the chevy and dodge np241 are clocked differently, is this true?? or am i better off just selling both the tranny and transfer case i have now and finding a dodge transfer case? thanks

So I got the motor in the frame now and waiting for my tranny to get here. But I ran in to an issue with steering pump. The vacuum diaphragms on the bump are hitting the power steering box so it won't go into the gear cover. Has anyone had this issue?

Use the later vacuum pump - no diaphragms to worry about... if you need vacuum. Otherwise there are compressors, or medium-duty steering pumps you can run in the same place.

What year? Are you talkin about the pump from 94 and up?

Anything intercooled.... 91.5+

Do you know if the vacuum with that pump will work for my ford? The brakes run off vacuum and the heater

The later cummins vac pump (vane type) works better than the Ford one.

What year pump has the vane type? And thanks for the help with this!

91.5+ like the diagram.

Ok thanks for the help!

Just curious what you decided to do for your transfer case? I am doing a 97 12 valve swap in my 81. I used the 97 dodge nv4500 (rebuilt and upgraded) and I am going with the NP205 with the advance adapter sleeve. Also all you need for the pedal set up is a stock set up for your truck (junkyard) and the stock clutch master. Don't remember what size the hydraulic line is for the master to slave you might need an adapter to connect the line. Be careful when buying a used trans unless you can see it in person and take the cover off and have a peek (still cant always tell if it's good)

I just bought a new nv4500 and I'm running the np241 since I got the Dana 60 up front. And I got the pedals from early 90's gas ford, but I'm running south bend single disc so I'm gonna run the ford hd HYD so it's easy when shifting. Good luck with your swap by te way!

Did you put the transfer case in already? I am running a king pin dana 60 in the front of mine but just curious how much room you have for exhaust etc around the larger transfer case. I started another post earlier what did you do for motor mounts?

Haven't put it in yet, I have 4" exhaust all way back so it will probably be a close fit but hoping there is no issues

---AutoMerged DoublePost---

i ordered the motor mounts from destroked, they where spendy and after looking at them i woulda tried i think to build my own. but they worked good. they have multiple mounting holes drilled for positioning the motor height.

---AutoMerged DoublePost---

i want to post some pictures on here of the swap but cant figure out how to post them

I can't see having a problem getting 4" pipe past the tcase on a Ford. Our 1st-gen Dodges have the exhaust, D60, and t-case all on the same side, and 4" gets by, albeit tight. Ford's frame is wider too. :tu:

Ya all I did was did little firewall work with the sledge hammer haha but ya looks like it should fit without any problems!

so im wanting to run the hd hyd for my clutch since im using a south bend single disc and i was looking online and the dodge one and ford one look identical. but can i use the ford one so it will bolt up to my fire wall or will it not work with the nv4500?
