Dont forget, weight equals horsepower. I dont remember what the ratio is but its something like 1 HP to 8lbs. If you could shed 300 lbs by gutting the car that could be substantial. Okay, I got my flame suit on.

We couldn't decide on a 400hp OM617 in a W123 or a hotrod 380SL engine in a W123. It would have to use all OEM Mercedes parts and appear to be stock. Someone talk me out of this, I know of a 300D local for $400 that needs an engine which would work for a donor car and a free 617 block.
Insanely modded 617

ok, How about just dropping in a spare new CDI engine?


Disclaimer: I have no problems with my vehicles speed, this is all speculation from fellow classmates. I have no real desire to do this to a W123 (although it would be pretty neat to see a quality job done).

Lightbulb Hmmm

A new CDI engine crammed into a W110, can you imagine it, Zooming up mountains, paying heavenly speeding tickets...
Wonder if it could reach 260MPH.

If you really want to do this it is going to take a lot of time and money, well to do a quality job anyway.

The trick is to build the car well enough and to a high enough standard that it looks like MB did it at the factory. Anyone can hack a 350 Chevy into a W123 and have a car that will go down the road pretty quick.

But what about a 5L M119 V8 into a W123 with some sort of imported 5spd? Do the install clean enough and it will look factory.

My favorite car was the 560SEC with a V12 stuck in it.

The problem with MB's is modding them is extremly costly. If you want cheap speed a Mustang or something similer is probably the way to go.

I agree completely. I wouldn't do it half ass at all, i'm talking about a M119 with a 5-speed type of thing. I think I will do it........... as soon as I make my first million

If you're going to go all out, don't drop a 5-speed in. A 6-speed is a must. 6-speed transaxle if you want to really do it right! Dunno if MB makes a transaxle like that, but there are setups from other makers out there that could be made to fit. Maybe the parts aren't all MB, but they are the parts that MB should have made

Personally, as person who was a teen not that long ago (24 now) and loves speed and cars, I think you should leave your current MB stock if it is in good shape. Find another chassis and mod the living daylights out of it. Preferrably, a chassis with a blown motor/trans (good excuse).
I own more than my fair share of cars, and these cars are just really good stock. Not fast, but well balanced, great riding, classy and just a joy to drive. Everything in a car is a compromise, and when you mod it up, you will trade off parts of this cars factory style. Some cars are just nice the way the factory made them, others were made to be built as much as you can afford to. (like my '77 Camaro <- note spelling) That's why car people end up with a collection of cars, so we can indulge all of our tastes when desired.

Build one that Maw Benz should have....

Get an old 380 SEC that "ate the chain" and a w126 what has rusted/walled the body (as in NASCAR - "walled" - to physically alter the external automobile shape by the removal of excessive speed when using friction with an un-forgiving, non-moveable object) and combine the two. Get a gear vendors overdrive unit to have 8 forward speeds on the automatic. Run a larger turbo downpipe and split it into the v-8 exhaust for more flow. Tune that sucker for all it is worth and then put propane injection on it for about 225 horse/300 ft.pounds torque. Of course, during the build, you could lighten componets of the auto (drilling, fileing, etc.) to achieve a lower overall weight.

Regards,

Run-em

Um, aren't transaxles for Front Wheel Drive? M-B's are all rear wheel drive, and have a transmission, a driveshaft and two split axles...

A transaxle is anytime the transmission and the axle are one unit. Most common on FWD, but also has been used on a handfull of RWD vehicles. The only one I can name offhand is the Corvette, but I know there are several European cars that were front engine, RWD with the transmission out back. Helps you shift the weight distribution closer to 50/50.

I am all for it. I satisfy my need for(cheap!) speed with my other car (under construction; upgrading the cylinder head, turbo, and injectors): 1987 Audi 5000 Turbo Quattro. I lifted the head and blew the gasket, but this was at 125 mph in 4th vs. a Subaru WRX (which the old 5000 ate up at the 20 psi I was running) and I enjoy the 300SD for what it is (beautiful, classy, rides the highway like a Greyhound Scenicruiser) but if you want to build a fast Benz... Might I suggest a cheaply acquired 560SEL engine implanted in a 201 or 123 with Megasquirt EFI? I've thought about this, I've also thought about an M117 in a W111 as I have a rebuildable 420SEL mill and have been checking out basketcase W111 coupes.
