| Hummer's 6.5lt V8 diesel transplant in a G-Wagen?
I have a 290GD.
I also have a brand-spanking-new AM General 6.5 lt V8, the one used in the military Hummer.
The question could not NOT be asked... Will the V8 fit in there?
Size is the same as a GM 6.2/6.5 V8 diesel (850W x 770L x 500H / 34"W x 31"L x 20"H), 410kg dry.
Has anyone done this before?
Thanks! |

I don't know if it has ever been done before, but I'm sure it could be done... providing that you modify the thing enough. It is definately not going to be a "drop-in" process and is going to cost a lot unless you have fabrication tools and skills. I've seen a G cabrio before with a 460 cubic inch big block Ford engine in it before (which is bigger than a 6.5 Diesel), and a couple like "G-zilla" with small block Chevy engines. I know that you will need to use a GM transmission in order to make it work (and it will need to be a 2WD version if you plan to reuse the G Transfer case). Since the 6.5 is similar to a Chevy/GM gas engine in design, you might start by looking at the build up of G-zilla on www.clubgwagen.com, this might give you a solid place to start.
Cheers,
Ben |

Ben,
Got a 4-speed GM tranny with the engine, 2WD. Intended to use the lot on my Range, and the ratios are calculated to fit its Borg Warner case and drivetrain ratios.
I'll have to build an adaptor plate and engine mounts, that's no problem. Exhaust may be a bit trickier, but can be done too.
Fit a larger radiator, push this, pull that, cut here, weld there, some hittin' and cussin', just week-end tinkering... 
Only point is... Do I really want to do it? The Range is already disassembled, chassis and drivetrain fully rebuilt, much easier to fit a new engine on it.
But the thought tickles me... I'm sure you understand the feeling!!
BTW, what's the dry weight of the OM 602?
Have a nice day!

Whether it could be made to fit or not......I would never choose to run that engine. It is very low power for its size, not known for good reliability, and IMO just a poor choice to replace even a 4 cyl 230G motor. On the Rover you would simply be replacing another poor excuse for an engine also built (at one time) by GM, that Buick based alum V8. That chassis probably offers more underhood room as well. Mainly I just think the 6.5 diesels from GM are among the worst engines ever built. |

Philip, It has been done before. Some friends of mine in Germany took an old junker W460 and put a cheap surplus Humvee engine in the truck. They used a manual gearbox from a BMW, but I have no idea which one. So.........you can do it, but please don't.  -Sean P. |

so tell us how your really feel....
While that motor is junk i did have a good one.. in 94 my pops gave me his diesel tahoe... it lasted 190K miles before i dukes of hazzared it over a hill one night on the river... bent thefram 18* straight up...
Long story short. they are not that grate of a motor and they are very slow. were talking 170 hp for th eturbo models, and like 120 for a na... you also need to think about where you going to put an intercooler and such... The reason these motor move a H1 is because of the geared hub.. while the motor make 400 lbtq on the turbo models... the geared hubs make it like 1400lbtq.. at any rate my tahoe was about as fast as G pulling a 5k pound trailer.

Never seen a Rolex trying to look like a Seiko..
... and you still want to fit a GM engine to a GWagen?
What is wrong with the current engine?
Unless it is totally cooked, the car will drive better with its current engine than with a brand new one from a Humvee.
Just my twopence. |

Why not just put a MB 5.7 Diesel from a Unimog in and switch out the axles? It would seem to me to take about the same amount of work. OT, but I read somewhere that the 5.0 and 5.5 are actually tilted in order to fit in the G's engine bay. Is this true? |

OK, OK....
Just to put things back into perspective, this was just an idle thought from an unrepentant tinkerer. The main reason for the "Why do you want to..." is "Because it's there!"...
My 602 engine is running fine, and I don't think I'll really start to rebuild the 290GD anytime soon.
The 6.5 is a Swedish-finished military block, some 200+hp on turbo. I think it will run fine in the Range.
The idea of the Unimog engine is appealing, though, and I'll keep my eyes open if I happen to see one passing by. In Switzerland, the Army auctions tons of vehicles and spares every year in April, and I promised myself that in 2008 I'll do the trip. As they run Puch Gs and Unimogs, chances are that a good deal may come up! |

Perhaps I should start a new thread but is there another engine, ( not originally fitted to the 460) that will fit in the engine bay and provide more, (but not to much for all of the other components) power and anywhere near the level of reliability of the 617 or 617A. I'm unfamiliar with Unimogs and other MB diesels, but there must be something that can be squeezed in there?

I don't know which diesels would fit, but I would sure like to try swapping my 280 for a gas GM 3.5L 5 cyl. atlas engine. Looks like a good fit and it would get rid of my CIS woes.

Well, why not go for the 4 cylinder Cummins...4BT. One guy popped one in his little 70's bronco and another installs them into Toyotas and the like. Now that would be cool.

You need at least a four inch lift to get them into the Toyotas. They are very deep. Nice engine, though. |

A Mercedes Benz V-8 from the 380 vehicles would fit nicely, tranny should be able to handle it too. I've considered this swap. It's a good motor if you get a factory rebuilt/factory fresh one. |
