F150 Gas To Diesel Conversion
 

Hey Bombers!
I was just wondering how difficult it would be to remove a 300 6cyl. from a Ford F150 4x4 gas and install a diesel motor, like a 7.3 (oh baby!)? Would I have to install a different Transmission? What about matching up the bolt to the engine mounts, would I need additional equipment?

P.S. What is a good source for used diesel engines?

P.S. This is for you Dodge buffs... Would it be possible to install a cummins diesel in a F250? No flammin' please ;)

Thanks, DannZegos

if you got the time and money its possible, you wont want to put a fullsize diesel in a F150, go for a 4BT cummins (4 cylinder) and it will fit fine and probably work with the tranny.....if staying ford diesel its just better to get a diesel that hassle with a 1/2 ton unless its a 4BT swap......

I agree, put the cummins 3.9 in there. Depending on what year the 3.9 will actually have torque then the 7.3. You will get better mpg then you can ever hope for with the 7.3 too.

And as for the cummins in a f250 absolutely it can be done.Try fordcummins.com, and destroked.com.
Destroked will do it for you.

what year is the truck and do you know what trans? If you have the 88-mid90s? Zf 5 speed manual a 4bt with ford manual adapter plate(came in a lot of bread trucks) will bolt right up. I know where you can get such an engine for around $1700 as well. Now I'm not sure about the half ton transmissions but I know for sure the 3/4 is a direct bolt up.

the guys over at www.4btswaps.com can tell you for sure.

Another big plus about the 4bt is that it should bolt right into the 300 engine mounts.

88-96 F150 stick wont have a ZF5 its going to have a mazda m5r2, good behind a 300 but a 4bt will tear it up

hey how much would that cost putting a 3.9 in an f150

my truck is a 1999 f150 ext cab short bet 4x4 gas engine had spark plug trouble so quit fixing and started to get parts to put 4bt in truck have all parts now have started to put in hope to have runing by spring hopeing for better fuel mileage than gas engine. will talk later i have $5000. in parts now.

HI Diesel Charlie, WELCOME TO DIESEL BOMBERS, Let us know how your project turns out !!

I've always liked those 300's, not fast or super powerful but smooth and torquey, well, more torque than a 300cid 6 cyl gas engine should have, anyway; an underrated little beast, in my opinion.

Is yours finally starting to die? An intercooled, 4BT would definitely be the way to go...the 7.3L's are heavy and while they're not necessarily a bad engine, I don't think it's worth the trouble or expense of doing an engine swap with that one, you'll be money, power and reliability ahead with the 3.9L 4BT.

as for a 6BT Cummins in an F250, that's by far the most common Cummins 6BT transplant.

hey i have a similar question, i have a 95 F-150 with the L6 in it and i wanna see if i can swap out that bad boy and put a 5.9L cummins 12V in that pig. cuz im talkin to a guy selling a 93 cummins engine for 500 bucks and its pretty mint. help me out guys

The 4BTA is a great engine for any 1/2 ton swap project. The suspension will handle the extra weight but I would upgrade to hydroboost brake (my experience). They help alot with the extra weight up front.
You can even drop one in a dakota or S10 with the right suspension upgrade. More work though adding the suspension and working in tighter quarters and a lot more work if you are working with a 4x4.
A turned up intercooled 4BTA gets you the same H.P. and torque as a 1st generation Dodge 6BTA; Again, my experience. I had a one ton 1993 6BTA before I made my half ton
4BTA. Expect 25-28 mpg in a 1/2 ton when you are not loaded down and about 15-17 mpg when hauling about 7,000#. The 4BT with the VE injection pump is really easy to turn up and double the H.P. and torque without paying a penny to do it. Another real plus. The only down side compared to newer diesels is that you are stuck with those settings until you climb under the hood and change them with some wrenches and screwdrivers. Not a bad trade-off if you are on a budget. It takes about 1/2 hour and some wrenches for me to change from stock 105 h.p 283 ft. lbs. to 180-190 h.p. and 383-400 ft. lbs.
You can go up to about 300 H.P. on this engine with twin turbos. Guys have used the
HY35W that has a smaller turbine cross section and combined it with larger turbos for the series setup. Expect something to rapidly show itself as a weak link if you do this. 1/2 ton truck drivetrains won't take this large of a torque in the lower RPM range for very long.
I also make bio-diesel if anyone needs more ideas on that. The 4BT is tolerant to fuel grade changes and thus lends itself well to bio-diesel useage. You just need to be sure you start off with high grade race rated gasoline fuel lines for bio-diesel exposure.

Questions About Conversion
 

Hi, I just joined this site, I'm wanting to do this very same conversion, 99 F150 4X4 extended cab short bed, 5.4, 4R70W auto, the 5.4 is shot, can you give me any advise on this conversion, I've been researching it for a year or more and want to do it real bad. I've read that the transfercase support, crossmember, is a real headache, I would appreciate any advise, help or insight. Thank You, Doug

that 7.3 b alittle too heavy for a 1/2 ton go with the 3.9

A newer 04+ F150 with a commonrail and a big lift would be straight up awesome!:U:

Thanks for the input, but I already have the 99 and am on a budget, my main objective is economy and the ability to burn WVO and biodiesel, so a cummins 3.9 is what I'm leaning toward.

5.4 to 7.3 swap
 

Hi i have a 2000 F-250 5.4l but the motor is blown. I was wondering what i would have to change to put a 7.3 powerstroke in it?

go with a 4BTA rather than the 7.3PS, read through this thread and you will find that the 7.3 is both lacking in TQ and is overweight compared to the 4BTA... and for the prices it would cost in upgrades i see the 4BTA as a better option.

Try and find a wrecked diesel truck of teh same year the start swapping parts. Or if your heart is not dead set on the 7.3 look into dropping a cummins in it. Alot easier to get it running. a 98 or older 5.9 cummins only needs 3 wires to run.

For teh original poster, I think anything over a stock 4bt cummins will destroy your driveline fast. Ando also you wont gain any payload or towing capacity with a diesel swap because you ares still running a 1/2 ton frame and axles.

hey guys i just signed up for the site because this thread is perfect for what im trying to do, i have a 1994 F150 with a 4.9 and something happen the computer because i have no radio, no speedometer,no odometer, and the shift points for the trans are all screwed up. so i figured im young im mechanically inclined so why not put a diesel in it. i can get my hands on a 7.3 for practically nothing and i was going to do it, but i wanted to do some last minute research and thank god i did. what do you think i should do powertrain wise?

i have a 2000 ford f150 5.4L V8 4x4 single cab long bed. iv been wanting to put a 7.3 in for a while now. i was wondering how possible it would be. i'm already upgrading the front suspension. im converting it to a solid axle(Dana 44) from a 78 bronco. if needed ill box in the frame if not already and add extra cross members. i was planning on buying a donor truck thats running and pull the motor out with transmission and install in my truck. if im missing anything here let me know and some helpful tips would be great. thank

I'm new hear but I bought a parts diesel cheap to get all the parts my only question is how much heavier will the 6.9 idi from a 84 f250 be than the 302 from my 92 f150

I have a 2003 F-150 and have been thinking about doing the 3bt swap. O r trying put 6.6 duramax in. Any insite would be great!

i see everyone here is talking about the v-6 motor. i have a 95 150 with the 5.8. it already has air spring on the front and 3/4ton spring on the rear. would you sugest the 7.3 5.9 or 4BT?

i say the 4bt, its small easy to put in, plenty of torque and good mpg

yo guys im glad to see that im not the only one putting a deisel in an f150 but im trying to put a 7.3 in , aparently some of you frown on that but ive got a 92 f250 to canabalize for parts ther is nothing wrong with the f250 that i cant fix but i think my 99 f150 would be nice with a strait axle convesion on some 54 boggers bein powered by my deisel . this wont be my first strait axle convesion but it will be my first deisel conversion i just wanted to see if any one could offer some insight as to the wiring and what i will have to do

How about Ford's new 3.5 ecoboost diesel engine. This engine is currently being use in the 2011 f150 and Taurus. I have a 2002 f150 supercrew and I'm thinking of doing this swap. Does anybody know what kind of problem I will encounter if I'll do this swap? Any information or suggestion will be appreciated. Thank you.

6.9 international
 

i was wondering how much stuff i would have to change over to put my 6.9 liter diesel out of a 85 ford and put it in a 79 f250 gasser i have the transmission that goes with the 6.9

300 c i d to Diesel
 

the original owner of this thread was asking about a diesel in a OBS Ford 1981-1997 !

I have a 1995 F350 that I put a 5.9 Cummins in and I love it!

I aquired a 1982 2WD ext cab short bed and a 6bt is going in there! Same body style and frame configurations and I can make engine mounts up in an afternoon :pca1:. Granted I'm putting a Steerling rearend in the back and going with a D60 (out of a 99 Dodge with coil springs) up front, because I'm converting it to a 4WD! It is an easy swap and I feal that the frame is more that stout enough to handle the Tq!

Keep us informed on you Dannzego ! :pca1::pca1:

NOT A DIESEL

---AutoMerged DoublePost---

Here is another option, if you can get one over here! its actually made by Ford. This is a variant of the engine they have been considering to actually sell in F150's here.

AJD-V8
Main article: Jaguar AJD-V6 engine

The 3.6 L V8 is built at Dagenham engine, It is a twin-turbocharged Diesel V8 producing 270 PS (266 hp/199 kW) and 640 N·m (472 ft·lbf). Production began in April 2006. It is very closely related to the 2.7L V6 version (same bore & stroke) and was designed at Ford's Dagenham Diesel Centre product development site, with input from Land Rover powertrain team.

Applications:

2007 Land Rover Range Rover
2007 Land Rover Range Rover Sport

A year and a half and 15k miles on my F150, little 8.8 holding up like a champ, mods in my sig :hellox:

To everyone else here who has posted, the most simple swap is one without electronics. A PowerStroke has electronics, simple as that. IMO, your best bet is either a 4BT or 6BT. You will hear that a 6BT is too much for a half ton, and not calling anyone else a liar, but that is not my experience, everything on the truck may go tomorrow, but a year and a half and 15k miles later, its all still holdin up. There is another guy on here by the name of cumminsF150 who also has a 5.9 in his F150. And beyond that, I personally know two guys with 5.9's in half ton Dodges. But it comes down to whatever you want to do :tu:

Eastern Aggie did you do any frame work on your truck?

Why ?:humm:

---AutoMerged DoublePost---

Dude, put that bitch in there and get some f 250 springs and call it a day :rocking:

I did not. For stock and mildly modified power levels, and daily driving, the frame will hold up fine. If I was going to be doing more mods (tuning, injectors, turbo, and up), and launching at the track, I would box the frame. But over two years with mine and its just fine.

I still want to know why you don't want a bad ass engine in a half ton truck

well plan on 500-600 hp eventually as of now the motor is a ppumped 24v fass fuel 181/210 cam cai exhaust 4kgsk mack rack plug and .93 injector lines with drilled out crossover tubes

A set of injectors, a set of DV's, and a set of compounds should get you there. You might even get away with a big single since you have a cam. You've got a pretty good engine to start with.

ya plan on 7x.012 injectors 66mm turbo 3pc manifold some sdx comp delivery valves and a dd sb street clutch with input shaft upgrade but gotta get some $$$$. How does your truck run with the mods you have now?

With just the pump tuning done, I could stay right with low to mid 14 second trucks from a roll. My launch would hurt me in the 1/4, I've really toyed around with the idea of a full billet auto, but I have other priorities right now. I'm pretty sure the injectors dropped me down to be able to run 13's in the 1/4, its alot more fuel. Once I get a new turbo and bump my timing, I see low 13's to maybe high 12's if I had an auto and good launch.

ya I would love to run a built auto to but it costs alot less to get a manual to hold what im gona have than a auto

my 89 f150 with a 5.0 has a Borg warner t18 which can support a 7.3 diesil
