Hey, you're getting there. If it were easy everyone would be doing it. Good job.
Mercedes 616/617 turbo diesel Astro build
NOTE- This is an old thread where all the images were lost due to broken links to photobucket in 2017. I have attempted to go through and upload images again, but some images may not necessarily apply to posts due to lack of availability years later
I been talking about this project, and after finally finding a "decent condition" Astro, time to start working on it!
The plan is to rip the OM616 65hp MB diesel out of my old Mercedes, adapt it to a NV3500 5-speed tranny, and put it in the astro van. The engine is also being mildly turbo charged. Its not built for it heat wise, but I should be able to get away with it, and a little extra oomph on hills would be much appreciated. Searching around, I discovered that the generation 2 passenger astro is only 600 lbs heavier than the 123 chassis MB I was previously using this engine in. I figure the generation 1 astro in the cargo version is closer to the 2 ton mark. The MB is around 3700 lbs.
Ultimately, for a fun swap project i am trying to build decent MPG manual tranny diesel work van. This engine was capable of 35 mpg in the MB with a .8 overdrive, the NV3500 I think is a .78, and I have to find a GM rear end that is close to 3.46, which was the MB rear end I had ready for my car. Stock, the 240 MB came with a 3.69, but with the turbo, a 3.46 would be better. Im not sure what the 1994 Astro has for a rear end, any ideas? If its not close, I will be grabbing another rear end from somewhere, or changing the gears.
Images of what the donor sedan looks like from wikipedia, the 207D that also was fitted with these motors (about the size of a express van), and a 1989 shorty recipient van-
