Project K-1 build, 75 jimmy gets the H-1 transplant

:rolleyes:

400+ ft/lbs of torque stock, skads of torque at idle, and get at least in the mid teens mpg in a good sized 4x4...yep, find a gasser that'll do that.:rolleyes:
 
That looks like a good build, but I can not figure out why you would put so much work into running a 6.5 diesel. I thought the power numbers were pretty low on these vs. a nicely built gas engine. Is the H1 diesel different from the other 6.5's?

Anyway, good luck with the build. It looks like you are making a lot of progress.

guess everything you don't know just serves to benefit me!!:wink1: considering this was a factory new drive train with less than 5000 miles that I picked up for less than half the cost of a new atlas t-case I think it was pretty good deal!!

besides who doesn't like a hummer??:D
 
That's pretty cheap. I spent $5000+ to rebuild my 350 into a CA smog legal 383 pushing 400 ft/lbs + torque. When hauling a 21' toy hauler trailer with tool boxes (filled) and ladder rack on my truck (estimated 15,000 lbs total), I get 5 mpg. When driving for work, without a trailer, I get 8-10 mpg. My truck has a built Th-400 and a GearVendors overdrive that I installed. I would hate to pull my trailer without having the use of 6 forward gears. I went with aluminum heads and a bunch of other nice stuff. I pulled the engine and had a good builder complete the engine from intake to oil pan. I put the water pump, header, and other accessories back on myself. I put all of my money into the parts and critical work and did the rest myself. It was well worth what I spent on it, but I am considering a low mileage 6.0l gen III for my 88 K5. The H1 diesel looks like its well suited for your rig.

Is the H1 6.5l the same basic engine as the one found in pickups? I did see that turbo is different. I don't think a diesel swap would fly for either of my trucks in California, but I have dreamed about a Dmax for the pickup. I'm a bit jealous that you have the time and space to do a project that detailed. How much of the build have you had help with vs. working by yourself?

Keep up the good work :waytogo:
 
The Hummer/HMMWV 6.5L is similar to the truck 6.5L other than the parts necessary to make it fit in the engine bay.

you can swap a diesel into any california emissions vehicle as long as the engine is identical year or newer than the vehicle. then you take it in for a referee inspection, and the vehicle will then be recognized by the state of california as diesel, never to be smogged again. pretty simple actually.

stoked on the liner!! it was easy peasy! I had melia help roll it out "she loves helping out dad"!!

sweet, it looks real nice in the pics. tell melia she did an awesome job.

my rigs will always be pre smog or registered diesels so I don't have to hassle with the smog stuff! much easier that way. The 6.0 is a great engine design wise, anything fuel injected gets a thumbs up from me!!

I went with the center mount turbo for a few reasons, the exhaust design is much less complicated "besides the firewall mods" helps spool the turbo quicker and provides the ability to use 3" pipe straight off the turbo.

Provides much easier access to the side of the motor for swaping fuel injectors, glow plugs and other mechanicals.

Gives me more room in the engine bay for dual batts, big honkin air intake canister and on board air set up.

I've had mucho help from my good buddy Brian AKA chickenrammit with the welding and custom parts like the crossmember, spring plates and lift blocks etc. I have very bare minimum when it comes to my garage, so some of the fabrication may not look like that stuff you see on them fancy tv shows! but hey I aint entering any beauty contest!!:D
 
85-m1028,
Are you going to referee your truck then? I saw that it is a 75. I hear that 73 was the cut off, but up to 75 may not require smog. Just curious if you will skate by that one. I wanted to do a 1996 454 from a 3500 c&c truck, that I could have bought dirt cheap, into my 88 k5. I asked a referee and found out that since the blazer is a half ton I would have to use half ton emissions. The 454 ss trucks were half ton. The referee said I had to meet obd I just like the 454 ss. The bad part was that by 96 or 97 everything was switched over to OBD II. Referee said no go. The multiport obd II would have been more work, but a better running engine, with more power. I'm not sure if a stock 454 OBD I would give me the performance that I want, especially for all of the work involved.

Since tbi seems to be fairly limited for power I am leary of trying to get 400 hp/tq out of a 383 fed by a tbi setup that passes smog. If my blazer wasn't so nice I would buy something pre smog or at least carbed like my 79. Is it true that you can not replace an original engine with a smaller late model engine (eg. replace 5.7 with a 5.3 gen III)? If that is the case I would have to go 6.0 gen III, although I want as much power as possible. The 6.0 should give me close numbers to my 383 for power but better mileage. Also, I could chip or supercharge the 6.0 and keep it legal. Now I have the diesel option to think about since you mentioned that it is legal.

Since you are doing a swap, do you have any good info on where to pickup a good 6.0 short of just buying a wrecked truck, and have you heard of a bracket to relocate the AC pump on that engine to avoid cutting the frame rail of a K5? Also if you have any links to info on the H1 diesel I would love to check those out.

I live in the IE and travel to the OC (55 and Katella) for work sometimes. I would love to check out your ride if we ever happen to be in the same area. Thanks for sharing all of your work with us, and I apologize if I am pulling your thread off course. I have given the swap for my blazer some though, but have not really talked to anyone who has experience doing it. The more I can learn the better.
 
Subscribed!! Sweet build....

I dont need to smog my 75... so no issues there.. the 6.2 diesel was a factory option in 1/2 ton blazers starting in 82 so everything for this project has been essentialy bolt in.

I recomend a diesel for anyone who wants to improve off road trail performance and keep it simple. sounds to me like you have a "clean" rig and maybe wheeling is not your main objective? at least the kind that would potentialy cause body damage.

I think the LS1 would be a good fit for your rig, fairly common and very buildable with lots of aftermarket support. check out craigslist auto parts and try to get something as complete as possible.

Off topic, but CGT80, I had a CARB certified motor swap in an OBD1 92 GTI with a 98 OBDII VR6 drivetrain swap. I had everything OBDII though to make it work, cluster with check engine light, OBDII diagnostic port, gas tank, EVERY piece of emissions equipment, its can be done, the guy who told you, was wrong, but its a lot of work, lots of trips back and forth. Here is the CARB door jamb sticker, sorry its blurry but you can see the year of the car as 92 and the motor as a 98 for the non believers! (I would be too)

xcalik5x,
the problem, according to the referee, with the 96 454 swap was that the donor was a one ton truck and that particular engine did not come in a half ton. I could not put a heavy duty emissions engine in a light duty truck. I thought it was b.s. though because the later engine with obd II and MPI should have better smog equipment and burn cleaner than the earlier obd I tbi engine that he would let me use. I did not meet the referee in person, but I got the feeling that they would have made my life hell. Thanks for the input. Where was the referee located that you used? Were they good to deal with?

85..... Your right. My rig is in very good shape. It has a great body with a decent pearl paint job, 6" lift and 35" tires. The interior is stock, other than the great stereo system I installed in it, and it still looks good. I don't do any hardcore off roading. I stick to forest roads and advoid getting her scratched. I can't bring myself to messing up such a nice truck. I also use it to run around on the weekends when not working, and to go snowboarding. Street performance, especially when driving through the mountains, is most important to me. I'm thinking a late model wrecked truck would work well. I could grab all of the emisions junk to go with the engine and take my time to transfer it all to the K5. I will search around, but is the LS1 a version of the gen III or is it a different platform? I don't have much experience working on any of the newer engines.

Thanks guys.
 
Nice build... Love the full verts...


I used to run the same poly tank before I installed the propane...
 
got to work on my fender chop "concept"

build010.jpg


build011.jpg


used some 14gauge steel to patch in the bottom, still ruff needs to be fine tuned but you get the basic concept

build012-1.jpg


build013.jpg
 
judging by where the tape was in the first pic, i'm guessing you gained about 2 inches of tire clearance towards the bottom of the fender?
 
Yup exactly 2" measuring 21 1/4" down from upper ridge line. I will trim the front a little more and 14guage plate the front lower ridge scroll detail about 1/3 of the way up.

The inner fender will need to be massaged or modified a little bit.

If I move the axle forward an inch and gain 2" high up in the rear of the front fender well, in theory I should be able stuff a tire roughly 5 inches larger in diameter? going from 35 to say 39"??

Notice the bubbles on the bottom of the fender! That's because the only thing holding it together was literaly about a 1/4" of bondo!!!
