Have you thought about putting a standard CJ or YJ front sheetmetal on it?

Kevo

Hell no!

I like the uniqueness of the 10 front clip, plus there is more airflow for the Cummins without pesky headlights and turn signals in the way!

How wide and how long is that bed? How heavy is it?

Just at 6 feet wide, a little less than 7 feet long.

Never weighed it, but I can (uncomfortably) move it around by myself, and 2 can lift it, maybe somewhere in the 300lb range?

Because the front axle is set so far forward, and the bed longer in front than back, it puts the wheelbase at around 126". Longer than a regular cab/short bed, but shorter than a regular cab long bed. If I had left the bed stock length, it would have pushed the wheelbase longer than my Excursion!

With the thought of the Cummins and 14b, I am fighting the urge to wire in trailer brakes and have it be the backup tow rig

Sweet build, it's nice to see something original.

Had you considered a 2 stroke detroit diesel? Probably a more difficult swap, i'd love to see one in a jeep. Either way, they are both great motors

keep the pics comming

Detroits are big, not that powerful for their weight, aftermarket support has waned through the years. It is even hard to find a mechanic what has worked on one enough to "run the rack".

There is a 3-53 on the board here, the motor is huge in the bay! A non dressed 3-53 weighs 995 pounds and makes 101 HP, a 4BT weighs 745 pounds and makes 145 hp stock.

I want this for reliability and long distance travel, and to be able to find parts quickly and easily. I want to be able to stroll into a cummins store, not have a Detroit Diesel store say they have to find their one tech that still works on gensets!

I do love a good Detroit, and it would sound AWESOME!, but alas, it will be getting a Cummins.

[gavan]

Now with 100% more Cummins!!!

I bought someone else's project tonight.

The Good:

Cummins 4BT
NV4500
D60 Front
14b/Detroit rear
Southbend clutch
New 52 inch Front springs
63 inch rears
DIY 4x spring hangers
WFO high steer

The bad:

It is all in some state of disrepair.

Nothing I cant overcome, but it will take some work!

The head is cracked (Common 4bt thing), motor will not start, but there is video of it running. The injector will not seal... (so he says) But, the KDP is tabbed, it comes with the stock turbo, a hx35y, stock aftercooler and the conversion parts to be intercooled.

The D60 needs brakes and king pins

The Chevy NV4500 needs a Dodge input and bearing retainer (He has the input, but not the retainer...)

Lots of little things.

But the most of the parts are here to continue the conversion!!!

I've been building a Cj-10A with my bestfriend though its been on hold for the wheeling season I hope to get the major fab finished up before winter, and get to Stabbing a 4bta into my rig, along with all the other projects I've got to do...

So needless to Say Really like the Rig and the powertrain you picked up for it...

I think if you want to set it up for pulling your going to wish you had a 6bt, but the 4bt gets the Nod for the Cool/wheeling/expo/econo motor.

Pumped to see where this is going...

I like the thought of a 6bt, and I almost bought several. I just could not turn down this deal, he had 90% of the parts I needed just sitting there.

I am going for cool, different, econo, daily driving with some occasional hauling. It wont be the fastest thing in the world, but with the HX35Y, a 3300 spring kit and some pump mods it should be in the 200 HP/500 FTLBS range. I should be able to haul a decent trailer without issues.

REALLY hoping for mid 20's, but it will be hard with 4.56 and 37s.

[MNtal]

It's nice when that happens. the 37''s should balance out that ratio well I would be surprised if you didn't get atleast mid 20's mpg wise out of it.

[robi615]

I love the look of this, old school flatty builds that you hardly see.

[gavan]

Whoops! I hate Sawzall accidents!





A very rough cut, just enough to get the front turned around in the garage so I can start mocking up the 4BT and NV4500 mounts.

The frame is cracked and otherwise trashed anyways, and needs new frame rails from mid-cab back. I need to get the Cummins mounted so I can see where the tranny falls, then see how much floor I need to cut before I patch it. Never ending!!!

[gavan]

Got the donor pig off the trailer and in the driveway

Lots of good parts, but it will take A LOT of work... a lot of stuff is half taken apart. I am sure the PO had a plan, but he did not share it

The NV4500. It came with a Dodge input and a southbend clutch, along with a machined flywheel and Dodge bellhousing/engine plate.

BUT, the tower is off and missing some bolts, and the top plate is only held on with 2 bolts, and who knows where the rest of them are. Oh well.



The Pig

I need to yank the 60/14BFF, springs and hydroboost still, then find someone to haul away the carcass before thee who rules the house (wife) kills me.



The motor

It looks like someone got a little confused when putting this thing together... I am going to freshen the head and get some new injectors. I have to spool the HX35 somehow



It will get together. I have most of the parts now, at least!

[rficken42]

dude great build. rough accident. mad jealous of the 4bt !!

[gavan]

Out with the old



In with the new



Out with the old



Soon to be in with the new!

Your build is coming along nicely! I'll be watching to see how your 4bt conversion goes.

I am looking forward to it myself! My SD33 had too many hours/miles for me to put the time and money into.

I stabbed it in last night, and it looks like it is going to fit well. I need to go intercooler and radiator shopping, but there are a whole lot of options out there and I should be able to come up with something good.

I have been talking with CrewCab59 on here, and it looks like I should be able to push this VE pumped 4bt to around 250HP and 500+ foot pounds. About 2.5x the previous output :evilgrin:

[MossMan]

what are you going to do the highsteer arms on that 44?

[gavan]

Put them up for sale with 5 8 bolt H1 rims, and a matching 10b/14bff 4.88 detroit f/r axle combination. I am going to try and sell the rim/axle/steering setup as a whole. It is a good width for Jeep guys

Interested?

[MossMan]

I might be interested in the steering and the H1's. Won't know for sure until next week.

[gavan]

4bt placed in the frame





Looks happy there!



Plenty of room for the starter



And the mocked up hydroboost



Shifter lines up good as well

There is a lot more room in the CJ engine bay than I remember, but the wide Wagoneer frame helps out a lot. The engine is 4-5 inches from the firewall, but there is a good 12+ inches from the pulley to the grill. Plenty of room for the radiator and intercooler.

I think I am going to pull the body and start looking at engine mounts

[yager]

Looks good !!!

great project!

i cant wait to see what you come up with next.

Heck ya! That M101 trailer box makes a great bed for the CJ10, and gives it that tough military look
Cummins 4BTA... oh yeah I like where this is going

That may be the funniest thing I have heard all year!!!

[gavan]

Ditched the body, installed the grill. Kinda backwards, isnt it? The body clearance is so good, I am now working on the front of the engine, which looks pretty good too!



Huge benefit of running the CJ-10 grill is is has huge openings on the side where the head lights would have been on a CJ-7, so lots of room to run my intercooler hoses. It looks like I can clock the turbo just a little more and make a custom intake hose, and the two inputs should line up directly with the intercooler, 2 90s, 2 straights, and 2 short straight pieces of tube and I should be all set. That would be f'n bad ass, simple, easy way to plumb the intercooler!



That picture also shows a little problem. I moved the engine down to make the hood fit well with the bigger turbo, and to lower my center of gravity, and fit the NV easily without cutting, blah blah blah, but now the fan hub is about 4 inches low. I know I can get a lifted fan hub from Cummins, but I think I am just going to run an electric fan. These engines just do not seem to run hot, I am not going to be towing heavy, I am getting a crossflow rad, I think everything should work out with an electric fan and a good shroud.

Another big problem with running the engine low is there is a huge drop to the pads for the engine mounts. I can run them opposite, Cummins puts the flat to mount under the bolts, if I put them over the bolts I can get about 4 more inches, but the frame mounts will still be about 2 inches below the level of the frame. Not a huge deal I guess, just needs more bracing!





The oil pan leaves a lot of room for the D60, but I do not think I will be able to run behind the knuckle "helicopter" arms. Oh well, I would like to, it saves a lot of space and gives me more options moving my axle forward, but I will deal



Getting there. Now I am just waiting for my power steering pump to make sure I clear all the engine mounts!!!

Wow this is a GREAT build!
