Sacreligious WT Chief converted to the Dark and smokey side Cummins 4bta

Teaser shots

The begining product






The interior already equipt with a NV4500 and a D300 twin sticked



After a little turd polishing we now have a modified scummins
thats getting closer to what i want to see when i pop the hood.

few new gaskets a new turbo, new intake, some paint remover, a new coat of paint. some lennys injectors no head studs YET but that may be soon. new seals and add a vacum pump and PS pump and Walla







Dont mind that oil filter that was the dodge filter assembly im going to have to go with a Remote mount system. just not on there yet.




Specs
CPL 857 120 4BTA with VE pump
Lennys injectors
Late model 2003 HY35/9cm
24V intake horn ...... going with a 1st gen dodge intake. the 2nd gen hits my brake booster
planning on 3" tube and a small air to air cooler in front of the AC condensor
6spd flywheel and 13" disk
NV4500 dodge bellhousing 1.25" 10 spline input 23 spline output
York Air conditioning compressor to be mounted above the alternator. im going to fab that bracket this weekend
Dodge Vacum pump and PS pump
Dodge Accessories
Nipendenso alternator with mopus external regulator.



1979 ahhhem CA .... 1974 Cherokee chief currently with a AMC 401 9.8 :1 pistons HEI Crane HMV272 496/512 cam single 3" exhaust with edelbrock shortie headers, Flowmaster 5 chamber muffler 70 series? AA bellhousing, NV4500 D300

I know im going to be selling the edelbrock shortie headers (which the seramic coating is flaking off of) , the exhaust if you are local, the Bellhosuing and input shaft, Clutch linkage ect since that is all BRAND new. Holley TA 670 might be up for dibs too.




The rig Before the 4" lift, bilistsins, 33"s and a life. still leaks water in places that drive me nuts but i'll tackle that next winter. im gonna try and emulate TNdonner's hydraulic clutch setup utilizing the ford master and dodge slave. that combo worked well on my 97 ford when i put a cummins in it so the only frustrating part might be installing a stud in the right location ont he stock jeep pedals. fortunately i should have no driveline or tanny issues as those are already mounted and running. pretty much change bellhousing. wled mounts to frame . remove motor finalize everything. insulate the daylight out of the floor and firwall ect and enjoy.




motor $1800
added parts, clutch disk, gaskets, oil filter adapter, remote oil filter, misc headaches, tylenol supply, excedrin, motor mounts, misc bolts $1000
intercooler tubing and hoses ebay $150 or less.
Hydraulic clutch parts $200
turbo i had, clutch scavenged from my dodge just added a new disk and input to the nv4500 $300

$3500 +/- at 22mpg it will take me roughly 40k miles to pay for this conversion in fuel savings. plus i drive the chief more and my truck less. another catch the 401 out of the chief is going in my cj since my cj motor ate a piston and needed a rebuild so either way i was going to spend at least 2k on a rebuild

4bta 4bt cummins 3.9 diesel

Its gonna be sweet! I'd eventually like to do a Cummins swap into my '84 Grand. Someday......... Right now I'm putting in a rebuilt 360 but can see the $$$ flying out the window in gas. Oil burners in these rigs are sweet.

Luck, and more pics as the swap goes along.

Dont worry the Coors light engineering department will be documenting this accordingly.

I jsut gotta keep the expenditures to a minimum since ive got a Wedding to pay for this fall.

Get the projects 90% done before you tie the knot. that way you already own them and the wfe doesnt see the money flying out the check book.


bare with me im taking my first vacation in three years during Febuary the soon to be and i are going dove hunting in Argentina......

Looks like it's going to be a sweet ride! I might be interested in the Holley TA depending on price and condition. PM me if you decide to get rid of it.

Not to hijack this thread, but what vehicles did the 4BTA come in and what tranny/transfer cases were avialable?

BTW nice truck. Once was a time when I wouldn't own a diesel, now I have two and really liking them.

Most commonly are found in Frito Lay delivery truck types. Not sure what else they come in.

cool thing about a 4bt is almost everything from a 6bt interchanges so you can mix and match parts wo make it fit almost any application.

a whole host of box vans. generator sets ect. they arent as easy to come by as a 6bt. the dodge 6bt's are the easiest to come by and have the most compact easy to come by parts. to put dodge tranny bellhousing and flywheel behind a 4bt you need the engine adapter plate, bellhousing, flywheel and apropriate starter. its a mix and match game but its fun to get it all figured out.

Nothing sacreligious about what you are doing. You are just doing something that the factory should have done!

If only jeep would have had the foresight to contact cummins and use the 4bt, they probably would still be making the FSJ's

sacreligious because im such a diehard 401 fan. but my wallet cant take the fuel bills much longer

In the process of redoing the motor mounts, i wasnt happy with the way the motor sat in there. more pictures to follow when i return from Argentina. until then you can all sit on the edge of your seats .

Also im still battling the fabrication of the York AC mount above my altenator. i'll get that finished when i get back also


Gotta paint my CJ tonight so it doesnt rust while im gone so the Chief is back in holding pattern

Cheers

Update:

401 came out today.

1990-93 dodge diesel intercooler fit it. the dodge intercooler is 38" wide by 13" tall. it takes some radiator support hacking but with a razor gille covering it up i didnt mind hacking it up the two outlets on the intercooler are a little tight around the rad support mounts mu with a little hammer pounding it fit.

not as nice as TNdonor but ive got a huge amount of surface area with this intercooler

using a cut and flipped dodge 12v manifold to get the turbo up up at a 45 angle. like tndonors J10 .... i still need to source a new dodge lower AC mount and tenshioner bracket but for now i can live without.

going to mount a ford 6.9/7.3 belt driven vacuum pump over the alternator using a kilby alternator pulley to get the accessory belt drive

more later but figured id post that something is slowly progressing
