diesel swap in wagoneer

[Texas wagoneer]

I am looking for a diesel swap for my 78 wagoneer....GM, Ford, international...who makes a engine and trans that will slide into place without a alot of fab work? Any Ideas or info????

[Glenn_tx]

Talk with "FSJeeper", he has done this before and he's in Houston. He might even be able to hook you up with everything you need. Email me at access4tx@yahoo.com if you'd like his email address.

[FSJeeper]

The GM diesel is the way to go. Fits perfect, no issues, and if you build it right, 300hp, 520 ft lbs at 1900 rpm and 20 MPG.

I have everything you need to do this for not a lot of money if you are interested.

[jenmal]

Hey FSJeeper, is that conversion valid as well for the 89 GW? Or is there another diesel/Tranny combo for it...

[bigun]

Hmm go with that and the thread that talked about burning corn oil could be on to something. I am just curous FS how long is that trany package you are running. got any pics

[Gargel-orum]

what would somthing like that end up costing? more or less then say A: stock rebuilt engine and trany or B: gasoline chevy conversion... or about the same?

Thats a good idea for a future project smile.gif

[FSJeeper]

The GM diesel swap will work in any GM diesel. A friend of mine has a cherry 88 wag with a 6.2 with banks setup in it. 21 MPG at 70 on the highway and plenty of power.

Do a search for diesel swaps. This horse was beat dead a long time ago. Lots of good information here.

I have 2 complete GM diesel engines, HD turbo 400's and 32 spline NP208's (passenger drop) setups. Also have turbo setups, etc. I do not need these and would sell cheap or trade for something I need. Both have less than 10K miles on them. These are the desirable J series engines used in military trucks and Hummers.

How much for one of those drivetrains FSJeeper? I bought a Blazer with a 6.5 GM crate motor,700r4 and 208, but it's nicer than I thought, and I can't convince myself to part it out.

[Woody Long]

Hey FSJeeper, I'd like to know more about the diesel swap, how much for those engines you got too?

[DieselSJ]

FSJeeper you have a PM and mail at your AOL address.

[Texas wagoneer]

Thank you FSJeeper...I know were there is a Buick with a 350 diesel and trans sitting around my block, I was wondering if this would work or would I have to mod the motor mounts trans mounts and the trans to the diff. I would like something that would slide in without alot of fab work. I hear alot about the 6.2 GM diesel....tell me more about this......what what would you want for a setup.
Thank you

[DieselSJ]

From what I have read, avoid that 350 diesel. Please correct me if I am wrong, but isn't that Buick 350 diesel just a converted gasoline engine? Either way, you want to look for a 6.2 or 6.5 for your Jeep.

[bigun]

What I remember of the 350 it was a GMC gas converted to deisel Iknow I have helped pull several of these things out and replace with gas

[ColeTrickle]

All this talk of GM diesels...UGH!!! :mad:

How 'bout a Cummins or a PStroke?

[Wilk]

Cummins and powerstroke are both possible, but very heavy, and very expensive, and most Jeep drivetrains won't handle the torque. GM diesels, by comparison, are lighter, cheaper, and better suited to FSJ drivetrains; if they're good enough for our fighting men, they're good enough for me. ;)

[ColeTrickle]

Heavy? By how much? Maybe a couple hundred...if that? Run 1 ton springs for that...
The only weak link I find is maybe the D20 that would be swapped out anyways.
T18 or Ford/Chrysler '94-up NV4500, D60/GM14..seems strong enough for me.

I'm not a big fan of GM, that's the only reason I asked the question.

I do see where this is headed....
Ford vs. Chevy vs. Dodge

[creeper]

One overlooked item is that diesal parts a pretty expensive at least up here in Alaska they are. injectors for a '92 7.3L (Ford) costs about $600 plus another $700 for thefuel pump. it costs about $60 an injector for a 6.2L (chevy). So that is one negative thing about diesals. other than that they're great.

[Texas wagoneer]

Thanks to everyone you have helped me so much...I am new to the jeep world and larger gas and diesel engines. I mostly deal with cars and small block fast engines.

I was wanting a diesel only for the power and cost of fuel. I have found out that a diesel is cheaper to run, but you will make up the difference with the cost of parts if you breakdown.

[bigun]

Dad always said for the price of ne diesel rebuild you could do 3 gas engines but the one diesel would last as long as 3gas engines so you pays your money and takes your chances I can't afford swap would be interesting would probable go with cummins my self but that is just me Dad ran cummins over the road never had a bad thing to say about them Detroits on the other hand only engine you check the fuel and fill the oil

[DieselSJ]

FSJeeper keeps teasing us with the "I've got a couple engines..." Anyone get a response regarding price?

FSJeeper? Hello? FSJeeper?

[maxrad]

Has anyone tried a Mercedes 300D?

I know that these are very reliable, however, I do not know if the power is sufficient or the swap even desirable.

[NomadJack]

I think there is a reason the Cummins and Powerstroke diesels are heavier and more expensive, it's because they are real diesel engines unlike the GM. Interestingly, I think the new GM truck diesels (I forget what they are calling them right now) are actually Isuzu engines (like the Ford Powerstroke is an International engine). The torque on those bad-boys is more than most modern trucks can handle which is why they are beginning to mate them to Allison trannies. I think there are people who've done a Cummins conversion, but it's gotta be mucho money to pull it off properly.

[Kemmer]

Heh, I have a 76 mercedes 300d. It one of the best diesel engines ever made, but they only make about 90 HP. As reliable as it is, I'd hate to have it in my Jeep!!

Although with a good Turbocharged modern diesel you can get some decent acceleration when necessary and they do post some decent HP numbers, diesels aren't designed for the high-end power of a gas engine. It's all about reliability and low-end torque (therefor towing capacity).

[jeepsr4ever]

whats wrong with the buick diesel?? arent the crank pistons and rods forged?? That wouold be a easy swap to do, heck they even had th400's behind them, i dont know the istory on them but i have heard different opinions, anyone know whats up with them?

[bigun]

they are adapted gasoline engines they came out during 70s oil crunch most were pulled and replaced with gas engine because they were neither fish nor fowl

[steamer]

Hey jeeps4ever, interesting to read all the 'experts' opinions about the alledged junk GM 350 diesel engine. I put an '83 350 in my daily driver a J-10 about 10 years ago, I disagree with all those that bad mouth it. I like it a lot better than the 258 that came in it. I pulled the motor a few years back, just for an internal inspection, no problems were found, I honed the cylinders re-ringed and rebearinged it, put it back together. It continues give me better than 20 mpg. I also have an Eldorado with a 350 diesel, it runs great, too. The one point that I will agree with, is to avoid the '79 and '80 model year GM diesels they are not the redesigned heavier engines. The only problem with these engines is that parts continue to be harder to find.

[Mikel]

I know very little about the 5.7 Olds diesel, but based on what I've heard, those engines were both victims of design problems, and the people who maintained them not being familiar with diesels. It's my understanding that the later 5.7's (DX blocks) were MUCH more reliable, after most bugs were worked out.

[jeepsr4ever]

hey steamer ive never seen one with a problem either......so whats all the fuss about them, ive heard guys swear bythem and swear them off

[bigun]

I had not known there had been a redisgn the last ones I had anything to do with was in the 70 and 80 and the shop I worked in at that time made quite a bit of money taking them out and selling them for boat anchors

[Paul]

I almost put a gm diesel in the Warhorse last winter--fsJeeper had the parts for a reasonable price, too. But, I chickened out and put in a 401. After buying a Dodge CTD in July, I often wish I had stuck to the original plan, especially with gas at 2.09 and with the 401 getting 9 mpg (lots of power, though!).

[Bob Barry]

The people on the Olds lists speak highly of the '83 and up 350 DX blocks, especially the Targetmaster replacement motors. I think some beancounter in GM's offices finally figured out it WOULD be more cost-efficient to build it right the first-time, rather than replace EVERY motor under warranty a SECOND time.

[243]

The Cummins 5.9 in the Dodge is about 1000 lbs dry if I remember correctly, about twice that of a smallblock. The springs are the easy part, but you probably need a D60 to move that amount of weight reliably.

BTW...FSJeeper is out of the country for a while.

[Maynard]

My dad has a 5.9 Cummins in his 75 chevy 3/4 ton. Its been in there for about a year, the 44 is holding up fine so far. I keep telling my dad to get a d60 but he is waiting to see what happens.

[bigun]

he belongs to the old school of if it an't broke don't fix it

[AM Woody]

My dad has a 5.9 Cummins in his 75 chevy 3/4 ton. Its been in there for about a year, the 44 is holding up fine so far. I keep telling my dad to get a d60 but he is waiting to see what happens.

YARGH! I hope he's not trying to tow anything. A D70 is the smallest thing Dodge ever put behind a Cummins, and many tend to fry bearings and spin carriers by 150K. They switched to a D80 at some point...

I don't know about these "late" 5.7 GM diesels, either. I'd stay away. A friend of mine, a professional mechanic, tried to keep one going for a few a years. People kept giving him engines and parts, so he would tear it down every year or so because it would go down. I seem to remember the main problem was breaking head bolts and/or blowing head gaskets.

I know another guy in the auto business who talked to Olds engineers at the time and they said the engine was NOT ready for production, and the guys upstairs pushed it out anyway. Maybe if you found one that was still running today, it would be okay, but the problems are not fiction. GM is single-handedly responsible for ruining the name diesel in the US. The majority of Mercedes Benz cars imported to the US were diesels in '79, diesel was getting popular, GM just wanted some of that action. Now MB hasn't even imported a diesel for a few years.

Stick with a 6.2/6.5 they're okay...

FSJeeper? Hello? FSJeeper?Sorry guys, just got back. Anyone who knows me will tell you I am completely unreliable on shipping stuff out on time because I never know where I will be from day to day with my job. They will also tell you I always deliver and I am just a guy with a hobby that has gotten way out of hand and am trying to get rid of stuff.

It is hard to through out a price. Depends on what you want. A low mileage military pull out 6.2
I would sell for $600. The HD turbo 400 and NP208 would sell for $400. Low mileage military pullout 6.2's go for up to $1,800 on the net so my prices are decent.

I also have some turbo setups, NOS 6.5 heads, and I have paid for a professional 6.2 rebuild but changed my mind on it so could throw that in on a deal for a price.

The time to crate stuff up and ship is a total PITA for me. I would prefer to do local deals.

[crispyboy]

Is there an adapter made to bolt a 6.5 diesel to the 727 tranny? what about the air conditioner etc....

[DieselSJ]

If you can't find any local guys to get the stuff and you get tired of tripping over it, shoot me a message and let's see if we can work something out on crating/shipping. Your prices are awesome. Too bad I don't have time for a road trip...
