simmonsm

Close up in the bread van here's the old 4.0 coming out once again Clayton Long Arms to clear the engine, probably going to have about 6"-7" of lift, I have 6.5" springs and ACOS to compensate for the 800+ lbs of engine SOA for the rear probably with adjustable shackles should level it out Hover Jeep The 4bt getting some love Next up I'm going to be mocking up some engine and trans mounts, then probably going to reinforce the inside frame rails.

I haven't updated in for ever but I have been working a bit on my truck. I have never mentioned it but my plan has always been to have a Cummins 4bt in my Comanche and I am finally on the way. I have torn the truck back apart and am rebuilding from the shell up once again.... lol Here's the van that the 4bt came from

Looking good, I have a silver door and fender left over from my conversion, I am also in Mt. Airy, Nc if you are interested

Third picture is my life/ other projects LOL

Wow, I can't believe its been since January, but I have the comanche running and driving, took it out on the town a couple time lol, but I have had life get in the way lol and a couple other projects, I'll post a couple pictures of her in the current state but still a long way from where I want it (long arms, 35s, lockers, ect)

Great looking truck, what part of virginia are you in?

I'd love to see another comanche with the 4bt, my ultimate goal is to have a 4bt into my 87' with my 97+ conversion and about a 6 to 7 inch lift, the 4bt is my only justification for long arms and 35s LOL, as others have said its going to be expensive but you also don't have to go as in depth with mods on the 4bt and keep it semi stock and a little cheaper, as 4btmj said he dosnt have stiffeners but has some extensive stiffening from both of his bumpers, also I wouldn't expect more than 20-25 mpg without some tuning and turbo mods, I think 4btmj said he gets about 28 mpg mixed and he has a laundry list of mods and also is sporting twins now, still though, CTD 97' Comanche would be the ultimate rig for me

Hey I am also looking into a 4bt with nv4500 for my comanche, going to be very expensive but great fuel mileage and the power would be sick. there is a very detailed thread on 4btswaps.com on that yellow comanche on 4btswaps, http://www.4btswaps.com/forum/showthrea ... uild-specs

I need a stock driveshaft for an AW4 and 242 shortbed, I'm not sure if there is a difference between lengths for the 231 or 242, I am located in NW N.C.

Wow, looking amazing so far, your really giving me inspiration for mine

So cool, I have always wanted to see a right hand drive mj, and this is even better with the new xj donor, can't wait to see this

Thanks alot, I haven't mounted the rear seat brackets yet, I have power seats so as soon as I get some power to the truck I will do that and post, there are a couple other 97+ swaps that may shed some light on that

I second that on the copperhead ring, I ordered mine and about a month later it finally showed up, that didn't bother me until I had to line the rings up, I had to drill out every hole in both rings to eventually get it to line up correctly. Roll bar is looking good though

I have been looking at a Cummins 4bt for my Comanche, although they are pretty heavy those hp and torque numbers would be easily met. Theres a good write up on 4btswaps.com of a yellow comanche with the 4bt, and he is reaching 30-35 mpg

Thanks for the kind words...

Maybe some pics tomorrow, I havn't gave up on the mj.... I've got most of the interior in and I have the engine and tranny both in, so since I'll have some time off this week I can hopefully get this thing running here soon

Jealous of all you guys with jeep gear and tools, I got a clock radio and tube socks....

So you work at Central Piedmont? I will be hopefully be at UNCC by the summer, and have my Comanche down there too...

Niceeee..... You have already saved me some time, I have a 99' harness and 01' console :cheers:

Thanks Mike, that sounds like a good idea. I will eventually wire the lights like you mentioned, but for the time being I rigged the xj plugs into the mj tail lights so all that I will have to do is lengthen the XJ harness.

When I put the ground from the driver's tail light area to the mj male plug it will be five wires from the mj to five wires to the xj, Any suggestions on better ways to do this I'm open ears, I can maybe clarify if no one understands this..... :nuts:

When I plug in the black ground from the driver's tail light to the MJ male pigtale, I will have five wires in the mj and five in the xj, I plan on using the mj male and female pigtail with the xj wires inserted in the mj female pigtale. If no one can understand my jibberish I will try to clarify :nuts:

Hey, this is Mark, I have been converting my 87' Sportruck to a 1999 and have finally got to the wiring. I have a couple of questions to the guys who have done this project before or are doing it now. First, since the XJ harness has splits into two harnesses for the tail lights and the MJ is one up untill the rear bumper, would I just cut say the XJs passenger side tail light harness and only use the driver's side to mate to the MJs? Also, I have the pigtail for the MJ which only has four wires (I removed the fuel pump lines) which are BLUE, BROWN, BROWN/WHITE, and GREY/BLACK. Now, all that I need to know is which wires from the MJ will cordinate to those ;of the XJ which hase eight wires, BROWN/WHITE, GREEN/RED, BROWN/GREEN, BLACK, WHITE/TAUPE, BROWN/YELLOW,BROWN/RED, and RED/ORANGE Of these eight wires on the XJs female three terminate and don't crossover to the XJs male, is there any reason for this? All this for these two plugs to fit each other

Looking good, that diesel engine is gonna be sweet.... I am also doing the 97+ swap and on the top of the dash I just cut the xj's top dash mounts out and welded them to the mj, but that may be a real pain with an oxy/ace torch and the thin metal, looking forward to more updates
