Has anyone heard of this swap? That is, shoehorning the 6 (or 7.3)liter V-12 into the W124 body style? How does the V-12 measure? Will it fit?

You're obviously nuts, but I like the way you think. :-)

Yeah, I may not have all my cards, but if Renntech can stuff the V-12 into a W-201, welllll....why not? It would make a pretty good sleeper....

Well they had to move the battery with the V8, I guess the next thing would be the radiator, maybe put it in the back or air cool the sucker

Woah, that'd be a tight fit!! I've never heard of it being done, but I'm sure if you gave Hartmut Feyhl a blank chack he and his cohorts at RennTech would build it!

I think it's unlikely a 12 can realistically fit, and given the number of tuners opting to go in the direction of 6.0-6.5 V-8 conversions it appears they agree.

I do like the way you think, though...and if you could stuff a V-12 in, how far out of the hood would the supercharger stick out?!?

You can physically do it, just how much do you want to pay to do it. I know that I read an article that someone actually stuck a 6.0 V12 into a E500 back a couple years ago, and things custom engine mounts and bushing needed to be made, but it fit. I believe the total cost came out to $40,000 for the entire operation. Now since the 5.4 V8 has more power and weighs less the the V12, I see no reason in doing such an upgrade. But there is an idea for you, see If a 5.4 would fit in there.

Actually, Brabus was the first one to do so in a E-Class(W124 and W210). The W210 EV12 and EV12T are the fastest sedan and wagon in the world.

Brabus has put the 7.3L V12 in E500, with moded tranny to coop with the massive torque....exterior-wise, it looks plan E500, but under the hood, it's different story..

Forgot to mention, it's real TIGHT fit under the hood of W124. You can barely put 2(I have fat fingers..LOL) fingers between the engine and the firewall

It's not really just a random thought. Here in Southern Cal. you occasionally see the $35k 500E, probably with a bunch of miles, and if you put $40 or so into it you'd still have less than what it takes to get into an E55. Mind you, I like the E55, but I dearly hate dealing with the new car process. And believe me, an E55 would never see this thing coming....it could be a real brute. Wonder how much the V12 weighs compared to the 5-liter?

Ah, fellow rabids...j/k

The swap can be done but there are many negative side effects to using the V12. Using either a 6.0 M119 (DOHC V8) or 6.5 M119 would still fit the current dimensions and provide nearly as much power. (420HP or so for the 6.0, well over 450HP for the 6.5) Though still shy of 7.3 V12 grunt it is still more than what the tires would deal with. Then you would have to change to gearing as the current setup is limited to 165mph (redline limited, not electro 155mph) 500E's had enough of a problem with running hot as-is, with the much longer M120 V12 it would only make things worse. Not to mention you'd rape the near 50/50 weight distribution. Another thing to consider is that you cannot (even at Renntech) fit the electronic 5-speed transmission in the W124 which leaves you to modify the crap out of a 722.3 4-speed or put in a 6-speed manual (available at Renntech). The M120 V12 is pretty much two M104's joined at the crank. If you had a W210 chassis then the V12 is a better fit IMO. So pick up an extremely high mile E320 and send it to Renntech/Brabus with a blank check. The only question is where to mount the NOS bottle...j/k

Jim,
Funny you should recommend finding a 500E and doing 6.0 mods....I recently got a line on a 6.0 Renntech E500 that is actually something that could be purchased. I would just need to sell my 95' C36 to do it. (silver/black, 65K miles, no wreck/hit/all original panels, perfect service, Mobil 1 3500 mile oil changes, excellent condition, etc) If you know anyone who might be interested I'm entertaining the idea of the swap (C36 to get into the E60)

Ah, the possibilities....Lee

True. What we really need is a tape measure, scales, and a couple of creative guys manning the parts microfiches. The weight issue is more of a concern to me than the "can it fit?" issue, 'cause we can make it fit. We can deal with underhood temps as well; there's no shortage of spiffy race radiators that can be adapted to fit. If you really want the 500E body style, it looks like the hydraulic 4-speed is the only choice. The newer bodies don't have the wider flares, which I think is one of the big mistakes in the marketing of the E55. That car cries out for the big bodywork.

I think Mercedes leaves out the flare on the fenders on E55s to keep the costs down. They can't no longer just concentrate on making quality cars now, instead, they have to update their cars more often just to keep up with other brands....

E55 with flare will sky-rocket the price, though I am sure all E55s will still be sold out...

Flaring the fenders would drive up the cost because:

- it requires another set of tooling to build(left and right). Tooling has to be amortized based on the number of cars expected to be produced. The E55 is a relatively low volume car.

- 2 more part numbers have to be created, stocked and tracked.
