Anybody thought of a diesel conversion?
YES. I have. Ive always wanted to put a diesel into my truck, but I dont know if its ever been done in my body style, let alone could be done. frames might be completely different. Maybe when they come out with the 1/2ton diesels they will work
its been done in the obs,
it can be done! you might need some motor mounts made but frame rails are similar ive put a 8.1 in a 1/2 and only one mount had to be modified and idk how well the Alison fits in a 1/2 ton trany tunnel the Alison isnt huge but its not small ethier
I have a Dmax engine and harness for sale. It has been done. I would use the 80E over the alison. That thing is just HUGE and just to build one out you are looking over 3500.00.. No trans brake options that I know of, and you have to modify the tranny tunnel area heavily to make it fit.
Luke so if you ever need a spare I have one. :)
wow thats good to know the frames are the same?
i dont think they are exatly i probably should measure both mine to see i know that the trany cross member is different and a 80e probably would be better for strip and i was thinking ats made a race type 4 speed but just checked there site and no 4 speed :sad:
but i do love alisons they are so easy to build and they are just a simple trans they are very cool i think :thumb: just not in a 1/2ton
id love to have one but just blew all my saved up $$ on mine but it was well worth itQuote:

You mean this one? This is one of my all time favorite truck pics. Its my wall paperQuote:

ok we've established that it can be done.What needs to be changed besides the obvious? I referring to ac lines etc.. I have a flex fuel tahoe so I wonder if my fuel lines will be ok.
What about the allison transmissio?. I read that 2005+ come in a six speed auto. That would be nice for gas mileage!!
It would probably be a lot easier to just cut the frame down on a 3/4 ton.
ok here is the run down on the alsion and such, 01-05 were a 5 speed 06+ are 6 speed there is basically NO DIFFERENCE 1-4th are the same and you can go to suncoast trans and get the 5-6 conversion it should be a valve body and a tuning issue, alisons dont work like a reg trans as in there is no drive driven and held in the planataries there is one drive and 2 driven the 2 driven are at 2 different speeds obliviously, this gives you more gears without having alot of planateries, there are 3 clutch pack in the trans 1-2 3-4 and 5-6 no matter if the trans is a 4,5,or 6 speed they are one in the same, they are also the simplest/ easiest to build trans ever ive built one within 5hr or so from tear down to reassembly, and as far as fuel lines go that e-80 is the same as any gas i belive you will need 100% new fuel system thoes lines are contaminated with gas i would never run diesel through them IMO
I would want a complete donor vehicle. such as 2500hd. You will need tons of parts. I agree on the fuel system. Diesals use a completely differant system. Pumps lift pumps etc. I would research a lot of info about diesals. They can be complex and nothing like our gas burners.
The Allison is not big it's FREAKIN' HUGE. BTW they 5 speed Allison has 5 clutch packs, 2 rotating and 3 stationary.
Nothing will interchange underhood. You'll need the complete electrical system with all the harnesses and modules, the complete fuel system, trans, harness, cooler lines, radiator, fan and shroud, crossmembers, fuel tank, cooler, and fuel lines, ECM, TCM, GPCM, FICM, coolant hoses and pipes....all this and the trans most likely will not fit the tunnel without a body lift. There is no lift pump on a stock DMax which why it is important to have perfect fuel lines front to rear....these things don't work well with suction leaks.
Lol yea that one too, but i was referring to this one 1970 Chevy C10 - Duramax Diesel - Diesel Power MagazineQuote:

Going to a different family of engine will require alot of work, nothing you can do about it. 1/2 trucks where not designed to have BBC or Diesel engines in them. But just like an s10-V8 swap its all doable... :) Take time and money.
Looking back I wish I had the coin to have bought the entire truck but it was more then I had, and I really do not want wreched vehilces laying around the property. LOL
Any how I have this one for sale, do not have the time right now to play with it. :(
idk why i was thinking 3 packs but its been awhile since i went through the class in all maybe it was that you take them out 2 sets at a time so that would make 3 sets???? i dont remember need to look at my notes but anyway its a cool trans but not for the strip IMOQuote:

What's really cool is the 6L's have the same shift/ratio design....takes only two members applied and holding to attain any of the gears so shifting only requires letting one element go and applting another (definition of clutch to clutch shifting that the Allisons and the 6L's have).
All that makes the valve body more complex but the guts are simple. This is also how they went from 5 to 6 forward ratios by only changing the valving and the tune.
New here and thought that this might enlighten the group...
i have a 2003 2500hd 6.0...ive always wondered about a diesel but never had the budget to resell...does anyone sell used duramaxs with the ally or how much do new ones go for( im guessing about 5)
5 might get you a used engine or a used Allison but not both. A new DMax in the crate is well north of $10K and a new Allison from GM is about $8K.
BTW, your gas engine 2500 is worth about the same as a diesel trade value because it's old enough to be wholesaled and wholesalers don't want diesels.
