hmmmmm. Some of you are plenty familure with the transpalnting of the 617 MB turbo Diesel into Mogs. That gives you about 120 to 125ish horses. Well I just read this on another board. Makes you go hmmmmmmm.

If you want a fast diesel, take an OM617, add an alloy head, throw an intercooler into the fray, turn up the IP, adjust the boost, and you can get 230 hp. About the same as the new C30 CDI AMG over in Europe.
That's what Mercedes did back in the '70's. And that setup was considered going into production.
On the third generation C111, Mercedes clocked speeds in excess of 200 mph with that diesel.
...
very interesting idea. Thoughts, comments (beside all the known tranny issue debates)?
Ok, the next logical question is why not do that swap in a 416 and have a modern chassis and good grakes to go with all that power?

I would guess because the 406 has a diesel in it already and more viable out of the box swaps are availble. Wont the IH 4bt fit in the 406/416? I think I remember it bolted right up to one of those two.
besides..... hehehe.... I own a dieselized 404 and not a 406 [8D]
Coach,
An interesting idea, but not as simple as the poster suggests.. The C111 is a "works car", strictly an R&D machine that probably had a sizable budget and a team of engineers. I dont think you are going to
find one of those alloy heads in a junkyard! :)
Some of us on other forums are discussing perf mods for an OM617A in a W123 sedan, the goal is to break 200hp without sacraficing too much reliability... General consensus is that this will involve lower conpression, higher boost, a reworked head, and possibly intercooling.
Unfortunately none of us are diesel performance gurus and the one guy who has already done it is not keen on giving up his secrets so I dont know how successful things will be! ;)
Is "the only way to go" to use a mercedes swap-in? Anyone using GM stuff? Cummins?

Could a smallblock chevy 350 fit without too much modifications to the cab?
NOPE. If you swap to a different body you can go a different engine. Even the MB 617 turbo is a very expensive swap. The engine is SHOE HORNED in there.
The Mog body just cant do a domestic engine. Not enough room. There is a few who built a bellhousing to fit 350. I can lead you to where to get this. BUTTTTT. YOU CANT FLY AT 60mph on the highway for more than an hour or so cause you will burn up the transmision. When you think Mog 404 think TRACTOR! It is not made for Highway cause it is not designed for that. BUTTTTTT. if you swap out the whole suspension and drive line and then go domestic engine you will be fine. Swap Body, engine, trany, Tcase, drive shafts and add a 4 link suspension to each axle, then your in fat city.
Hehe, ok, seems I'll keep the original engine then and do some mods to it, and when the body falls off due to corrosion (lot's of road salt and shit here in Sweden), I'll swap in all of that stuff. I'll probably have to save for it whilst waiting for the body to fall off, since a Chevy 350 come expensive here in Sweden too... Thanks for the info!
I will gladly donate a free clutch to anyone who runs this kind of HP through a 404 gearbox. I guarantee they will need it, as well as reduction gears, and most likly a new gearbox.
That kind of HP would be nice on hills, acceleration (if you can shift fast enough), and would sound real impressive but other than that your top speed probably won't change, a 230HP MB diesel will most likley still have the same Max RPM range. I have driven 404's with measly 1.8L 4 cyl diesels (top speed 60KMH - time 0-60KMH must have been at least 60 seconds) up to a M130 dual carbed High compression head 404.0 that would climb hills nicely, and would cruise quite happily at 95KMH above 100 and it sounded like the engine was going to hop into your lap.
Someone with alot of time on their hands could definately take a donor mog and slap in a larger V8 (mounted in the bed with a shaft to the gearbox) however how it would perform and how many reduction hubs he would cook/destruct would be interesting.
I'm not after top speed... at all. I'm a slow guy, on ALL levels :)
I want the "oomph" combined with preferrably an auto gearbox to get that "instant" power/wheelspin when needed. I'm a "crawling" guy, and the overall low gearing of the mog is prefect for me, but I still want the "blip-of-throttle-response" out of my vehicle.
I have a Volvo "Laplander" right now, which I'm about to sell and get a Mog instead, and this vehicle also has the low gearing (5.38) but sports, like the stock unimog, a low powered gas engine (Volvo B18, 1.8L) with NO available "instant" wheelspin/speed capabilities.
My friend swapped in a B230F (From a 745) with injection and a BW 3spd auto tranny (in his Laplander), and WOW! He's got EXACTLY what I want, slow crawl ability and wheel speed response when he needs it.
I don't do almost any on-road travels with my Laplander, and I sure don't plan to do any more with the (would-be) mog (404 is the "dream"). I'll drive to and from events, no farther away than 30km. I also like how people look at the vehicle while you cruise along at 50km/h, the vehicle becomes an attraction :) It's fun to be the centre of attention, sometimes...
The wheelspin is what will get you in trouble. The reduction hubs just aren't designed for that kind of torque. I hear horror stories about Jeep enthusiasts who spend $4,000 on a set of new 404 axles for their jeep only to blow out a reduction hub when they put 250 plus HP through them offroad.
Not that I am saying you should avail trying to improve your unimog, I just think expecting a tire-smoking bog-vehicle is asking for trouble as is expecting an SUV you can cruise in at 100KMH plus for hours on end.
