6.9L Turbo convo. (1 Viewer)

[Andyvillen]

Hey dudes and gals... just wondeing if any one has ever put a Navistar 6.9L from a 86 F-250 into a 60 series, HJ-60 to be exact.

the f250 is a ext. cab long box. and it has a decent amout of get up and go for a land yacht ( has a ATS turbo kit on it ). plus it can pull a house. i can just amagine how the HJ will move with more than twice the power, and probably more than 3 times the torque.
I cant wate! lol

i also have 2006 axles Front dana 60 high pinon, and a sterling 10.25 rear with a limited slip woo hoo.


let me know what you ppl think, and any ideas will help me alot.

destroying a good HJ to stick a ford motor into it is a terrible sin. you will burn in cruiser hell for this, which is a place where everyone has to drive an explorer, but I think you deserve that.
why not start with an FJ60 at least?

sorry, no constructive comments on the doability of the swap.

 

[dieselcruiserhead]

sounds like fun. Sure would be a large powerful engine... I have driven the same think but the 7.3 with a ATS turbo. Nice but sluggish. If your 2H runs well then I'd turbo it and call it good. You'll definetely be miles ahead price wise. Messing with the ford stuff will be a bitch. Especially getting it out of the ford because there is just no room in there.. The ford swap would be a good 'advanced' swap, fabrication motor mounts etc. But would be fun

Actuallllly......
Its a Navistar Motor.... Ford buys the motor off of international. so there lol!!!
;p

The 4.0 is a bag. it dosnt have piston skirt cooling, and its just not big enough. i want to be able to pull a full size camper trailer at 100 Km/h and not have to gear down to 2nd to make a hill.

If I remember right, the ATS turbo mounts at the rear of the engine behind the intake. The HJ60's firewall is recessed in that area for the 6 cyl engine. So it probably would be a nice fit in the back. You would get some heat radiating into the interior unless you got some insulation.

You probably would have to put a spacer plate between the frame and steering box to move the steering shaft out.
My GM 6.2's exhaust manifold touched the steering shaft, so I'm sure the 6.9's would be wel into it.

Not much room up front for a motor oil cooler. You would probably would have to go without or get a water cooled oil cooler and mount elsewhere unless you get a radiator with one built in.

The Land Cruiser radiator would probably cool it just fine unlees you are towing heavy loads.
I say go for it!

Thanks for the heads up. I actually sold the steering box off my parts truck ( the truck im mocking every thing up on) so i'll have to find another box or i mite be able to use the one of the f-250. i havent even looked at the ford really though. As for the rad i have a 97 F-250 rad. pretty big.. but i can make it fit.
i do plan on pulling heavy loads. the Hj is going to be my tow rig.

The 6.9/7.3 Navistar engines already have a block mounted oil cooler on the left (drivers) side of the engine so you shouldn't need an additional oil cooler. I am really interested in how this conversion works out because the Navistar engine is a much better engine than the GM 6.2/6.5. I'm not just pulling that opinion out of the air, I work in a diesel repair shop and we see alot less problems with the Navistars.
I think the biggest advantage to the GM engines is the smaller size and the availability of conversion parts already. The best of those engines would be the '93 6.5L HD with oil cooled pistons and the mechanical injection pump. These can be turbo or naturally aspirated.

 

[FL cruiser]

You can user the stock Toyota steering box, no problem. You'll just have to make a spacer plate to go between it and the frame and then just lengthen steering link bar to compensate. You may have to trim some metal out if the lower inner fender panel toofor the steering shaft.
If you go with the bigger radiator, you'll end up having to use a different A/C condensor and different A/C hoses.

Will you give me the 2H?

 

[Andyvillen]

Lol every thing is for sale. but not right now. im still driving the 2h.

i have a second frame and body that im putting every thing on, then i'll swap the body out.

And as for a GM 6.5l they are garbage compared to a Navistar enging.. mind you all engins will develop a reputation.(except toyota lol). but the 6.5 is known to be a boat ancor. Here in Sudbury the mines have the last 2 years of the 6.5 01 and 02 i think. and with in a year almost every truck had like 6 engine rebuilds..

the only thing im not happy about is loosing my Inline injection pump. the navistar uses the rotery pump. its all fuel lubercated.(not the best idea). really bad when u run out of fuel.

 

[FJ40Jim]

You're right, the rotary pump is not as robust as an inline. But they are cheap/easy to have rebuilt.

If the engine does run out of fuel, just fill the tank and flip on the electric boost pump you wisely installed back by the tank. It will pump fuel back to the IP and bleed most of the air out of thesystem, before the engine is even cranked. Did that on my 7.3L and wow, it made cold starts a bunch easier.

I like my 7.3L and ZF 5speed (in a F350), but I would still prefer a Toyota diesel and H55 in a Cruiser.

wooouu nice proyect ..

Navistar with axles .. did you have plans to make a trial rig with 39.5" iroks .

its going to have 38 or 40 inch interco Trexus STS's hopfully.. and its going to be a mild off road/tow rig. i have a 86 ranger sitting on a 79 heep cherokee frame, 360 v8, granny tranny. thats my Beating up rig.

i dont have it in me to bash up a toyota in the bush any more... thats what fords and jeeps are for.

I have said it once and I'll say it again: 60's do not make good tow rigs. I have tried. I have a 4BT in mine and yes it will pull down a house. But, I have pulled a FJ40 on a 16ft flat bed trailer and it was all over the place. It pulled fine up to about 50mph. anything more was just too dangerous. I tried adjusting the weight on the trailer and nothing helped.
If you want a tow rig, stick with your F250 or any other 3/4 or 1 ton truck. Just my thoughts.

 

[Andyvillen]

Hmm

did your trailer have Torson bars.? they go between the hitch on the truck and the trailer.

i havent seen newer trailers with them there an old school thing. but any way my uncle has a Bronco 2 with a 302 in it. and he tows a 78 double axle 20 or 22 foot camper. cant keep the thing on the road with out the bars.. but as soon as you pop them in its like a whole new truck. if he can pull that with his truck, i'll be fine pulling a car trailer.

and keep in mind the suspention of the truck has alot to do with towing.

 

[HZJ60 Guy]

That engine isnt great first off, and it's to dang big secondly.

Cummins 4BT!

Either way, good luck.

I used to have an F350 with the 6.9. I tried towing my FJ40 on a trailer a few times with it and it was painful. It'd do it no problem, as long as you weren't in a hurry. 45mph up hills max.
I added a Hypermax turbo to it (and a GV overdrive) and it helped, but it still wouldn't do over 60 mph up hills pulling the trailer. I'm talking Texas hills, not mountain passes.
For a Diesel though it was a quiet and smooth motor. Running empty it was very nice.

I know its big.. and its a better motor that alot of other diesel motors. ( the 6.5l chevy ) talking V8's that is.

 

[FL cruiser]

Having owned one, I don’t think a 6.9 is that great either. About the only engine it might be better than is a 6.5 and that’s about it.

I'm planning on pretty much the same swap in my 83 "FJ65" project. I have a healthy 6.9L Navistar, T19 trans and t-case out of a 87 F250. I really want to use the stock Toyota axles(beefed up a bit), but I'm wondering about the offset diff and the Ford t-case; I guess I'll cross that bridge when ever I get to it. I'm going to fab all of the mounting brackets and such(Ford used a huge, bulky crossmember under the rear of the engine and one under the t-case, made working on the engine a royal pain in the ass), I imagine there will be a lot of "custom" fab work done to make this work. I'll be doing a SOA to give me a little extra clearance between the oil pan and front the diff; a 4Crawler body lift will also go in if I need more clearance. After spending plenty of time around this engine, it's a pretty simple unit, I think mounting and aligning it within the FJ60 will be by far the hardest part. I'm interested to see your progress with this, post a plenty of pics of the install
