Building a Jeep Comanche Truggy, 6.2 6.5 swap help

[hookedup50]

Leroy that does look like a good start for a project. I've wanted a CJ8 since they were new. You guys that don't live in the rust belt are lucky, as you get better starts on projects.

On the van turbo (same as hummer turbo):
It's a center mount c6. It mounts where the fuel filter mounts on a normal truck. The intake manifold bolt holes in the head are a different angle, so you need van heads,intake, up pipes, turbo. And then you have to drill the block for oil supply and return for the turbo. Complete tear down for that. I kept the truck (also n/a) heads and custom made intake mounting studs by bending gr.11 threaded rod, high heat treating, then cryogenic treating them. Then replace the intake gasket 3 times just learning to not tear it by how it puts a side load on it instead of even direct pressure.

It can be done. If you have any other options, choose plan b. Remote mount your truck turbo, it will be far less work and then you can add a qsv, or upgrade the whole turbo once you realize how many better turbo choices there are out there. Maybe put the turbo in that spot, and custom build your own headers/ up pipe to feed it as a center mount. Otherwise where ever you can fit it.

What is your upper end rpm going to be, under 2200 I hope wih any gm turbo. They will go above it, they just don't like it.

yeah swappping heads i can do but im not... lol... thanks for the info! ill do some researching on pretty much anything else lol... sounds like more work then moving my hoop lol... building my own exhaust setup and intake tube work is possible... i was thinking of moving my radiator to the back... the motor will fit without doing so but itll be better weight distribution as im light in the rear... and i was thinking about running a intercooler...

Our old 6.2 when it popped a belt it took the other one with it. Happened rather frequently compared to the serp set up.

WARNING! I'm in a wacky mood so...

Move the radiator to the back like your saying. Regular electric fans might not be enough though, maybe run the dmax fan off a 1 horse dc motor and twin alternators.

Custom headers going down and to the front of the engine. Come up and mount an ATT turbo in front center where the fan was. Back up top through cut outs in the hood and 1 or 2 stacks straight up. Or even back down the traditional direction if your not a stack guy.

With the ATT you are moving more air volume at lower pressure so there is no need for an IC because the air is not compressing as hard and does not heat up as much as the factory one. (That's for real, not in my crazy scheme idea). Loosing the under sized gm turbo is always a good idea.

Now I have to work on this 50 cal. turret Hayabusa side car mount idea...

sorry just seen this lol... ATT?

The problem with exhaust existing anywhere in front of the jeep is that in crawling your moving very slow in most cases and sitting around a lot waiting on others to finish a obstacle all at idle... sitting in exhaust is no fun so as far away behind ya as possible is best... it may not be to bad tho?

the exhaust does look easy to build my own tho... and i may have to even though it would be nice if i didnt have to...

Thanks!!

I was gonna suggest hood stacks lol. Make it just tall enough that it clears head level, I bet it will be a touch loud though!

[huntingman2706217]

can yall name these items? sorry im not sure what pics what in the row now since the number was changed...

the lines i pictures are oil lines? maybe ran to a oil cooler? is this needed for the engine or just something nice to have during towing and such? cause thats not gonna be happening lol...

Another pic is wires coming from the fuel filter? are they important to my swap? i wouldnt think so as im guessing they are just sensors or some sort

Another pic is two other plugs coming off my injectors pump... one looks like some kind of map sensor or TPS... from my understanding its a mechanical pump style and i wouldnt have a issue trying to figure out much wiring so hope this isnt needed either? thoughts?

the rest are just normal sensors i know... oil pressure... coolant temps... but im not sure which all is which and which of the others i can block off... and no idea what some of them are... the water temp is pretty much given but just double checking... if you know please list just top to bottom... thanks for the help! i could figure them all out eventually with some research i know but maybe someone knows just off the top of their head...

thanks again!

1 water temp (guage)
2 OPS
3 oil cooler lines
4 engine speed sensor?
5 fuel heater and WIF Light
6 fast idle
7 glow plug wires
8 water temp (PCM)
9glow plug relay/controller
10 looks like wires from an electronic IP

The whole thing seems like a combo of 2 diferent engines to me 1/2 mechanical 1/2 electronic

 

[huntingman2706217]

lol thanks for the help man! couple of these ive never heard of so will check them out... the motors from a 92 which is suppose to be one of only two years that was the mechanical fuel pump... so i dunno... lol...

 

[huntingman2706217]

i do know the injector pump is fly by cable tho

 

[huntingman2706217]

and i think i need to try and get the engine harness from the same truck to save me on some plug rigging... i didnt think there would be so many i may would need lol...

 

[ak diesel driver]

If truly mechanical there's several sensors you don't need

once i get this thing apart a little bit ill check numbers and match up pics of others just to be sure... he said his grandfather owned the truck since new and hes had it about 10 years so everything original minus the crank pulley

i need to get the front half of this cherokee up here under the car port so i can see if this is gonna be easy.. hard... or not worth it... lol

 

[Burning oil]

It all looks correct for a 92-93 6.5

All you need is 12volts to th IP and starter and it will run.
What trans you going with?

 

[huntingman2706217]

Originally I was gonna keep my AX15... They can hold up to a mild built 350 figured they could here... shares the same input shaft as the nv4500... so clutches would be simple... but I think I'm gonna go with a th400 now... autos are easier to work with offroad and it's strong enough... and no exspensive adapters... probly run a 242 behind that from a 88+ chevy... hopefully ill find a th400/241 combo already setup...

Thanks on the injector pump info... I'll figure out which wires needs power and ground at some point as well!

So came across a guy selling a 82 reg cab c30 flat bed 6.2... offered to trade my 94 bayou 4 wheeler and small crappy trailer for it and he took the offer... i had $1500 in my quad which was spent 3 years ago so IMO it paid for itself in use and basically feel like i got the truck free!

It was a old farm truck mainly kept under the barn... has only 99k and no i can tell it hasnt rolled over... no oil leaks... everything works including AC, horn, cigg lighter... i mean everything... has one small ding on the body but otherwise no rust or dents... really really clean... interior has normal wear but since its a stripped down farm truck it never had the extras... no pillar moldings... no chrome on the doors... no nothing on the the doors actually other than just the plastic cover...

he replaced the batteries with some wal mart 650cca and that didnt last for me... already melted the positive off one of the batterys lol... it does have a tough time starting if its been sitting and does blow some serious white smoke when its cold but after its been running its good to go... 14blt rear locked with 4.10's and 4 speed with granny low... he also replaced all the glow plugs and put a dang toggle switch on it... i hate toggle switches... wish people would just fix things the right way... so ill be addressing this...

also the bed is original and ALL wood... 4x4 cross beams and everything... done very well though considering... the 2x8's are starting to let go though so im gonna find a steel flatbed or have one built... my plans for this truck are to restore and make it my DD/tow rig...

ive also thought about beefing up the 6.5TD and sticking it in this truck and sticking the 6.2 in the comanche... would solve my turbo fitment issues as well as make my DD/tow rig perform much better... im also looking into making it 4x4 a little at a time... ive read its not easy but fabbing isnt the hard part... finding the same tranny in 4x4 is... i guess its a sm425 or whatever? if i can at least get a axle under the front id be happy to ride on that for awhile though...

The beds about 2ft short of me just driving my MJ up on the back... i may be fabbing something up where i can do this and make it removable off the back side so it looks normal unless ive got the jeep on the back... like a flip up extension in line with the tires or something... need a solid flat bed first though... woods cool but it aint gonna cut it...

heres a couple pics of it i took today... i swapped the HID's off my MJ to the truck and trucks to the MJ... im trying to eliminate wiring issues on the MJ offroading... wires dont like to be beat around much and im always loosing a ground or something...







Something like this is what i would like... may have been on this site but cant remember... its a beauty though...

 

[huntingman2706217]

been a minute so figured i would post some pics of the crawler in the wilderness...

yesterday i was suppose to pick up a transfercase a guy was looking for and turn around and trade it for his built TH400 and 208... but i got stuck on OT at work and didnt make it... hopefully i can score it cause it would mean having my th400 for my build... then sell the 208 and figure out a case that will work for me... the 241 is not gonna work after some reading...

I took the accessories off my 6.5 the other day and stuck it on a engine stand... been hanging from my hoist this whole time lol... the flywheel and dampener are deff both shot... so they went to the garbage... hope to get a chance to strip it down some more tomorrow but i got some other things i gotta do today to the crawler...

Looks good, what part of the country you in?
