how to swap m156 motor into 09 e250?
Hello. I want to know what would it take to put an M156 motor and gearbox in my E250. I cannot buy an E63 where I am, they are too expensive and scarce. The difference between normal Mercedes cars and AMG is really large. Mercedes cars can be bought very cheap, very good price but to discourage from high emissions AMG cars are too much.
Which parts would I need to put an M156 engine & gearbox in my E250. I have found a very good price on a M156 engine and MCT gearbox but can anyone give me some idea about the rest of the parts I would need. I really want to do this and there is no option for me to buy E63. What are the challenges of doing this?

No matter how expensive a E63 is where you live, it will still be cheaper to sell E250 and 63 engine, and MCT and buy an all ready built REAL E63AMG.
Radiator
Condenser
Oil cooler
Alternator
Air conditioning compressor
AC hoses
ECU
Engine harness
Engine mounts
Fuel lines
TCU
Trans harness
Transmission mounts
ATF lines
I could go on and on, it is NEVER cheaper to build your own. Unless your time is worthless.
Exhaust X2 + rear valence
Fuel pump for 63
AMG brakes
Differential
Half shafts
AMG rims + tires
Sport shocks and springs
Then there is the interior
Gagues
Seats
Don't forget the AMG badges.
Just a bad idea, sorry

You gotta understand that the metal shell chassis for E63 and E250 are the exact same. Meaning you can swap everything over as a direct bolt on. Yes some brackets might be different and of course wiring and other issues will arise during the install but it CAN BE DONE. I have taken apart plenty of W211s and if we tried it, maybe 1-2 weeks.

you misunderstand. i dont want to build the car to be like e63 amg. i just want to make the engine,gearbox,differential to work. i dont care about changing the gauge or seats or even brakes and suspension. im trying to just make the m156 and gearbox to work.

Here's how to do the swap.
Make sure you have a good engine crane.
Loosen the license plate bolts
Attach the crane to the license plate firmly, then remove bolts
Raise the license plate minimum 1.75 meters
Remove 09 E250
Replace with 09 E63
Lower license plate to desired height
Reattach bolts to license plate
Put away crane
Oh yeah. I forgot. Always block the wheels and remove the negative battery cable before performing any work.

You might have a E250 with a 6.2L V8 but that won't make it a better car. The car is more than the engine. Everything on the E63 has been designed to work together. The airmatic rebound/compression, the ride height, the brakes- how will you make it stop? the exhaust, the differential, the traction control, wheels, steering, tires etc not to mention all the electronics to control these non-engine related things. The car will be a lot faster but it will not be a well rounded enjoyable car.
Where do you live? Surely you could keep the E250 and buy something that is affordable and has or can be easily modified to have exceptional performance.

I don't think it cant be done.
As stated above the engine has a lot of controls, sensors, wiring that is tied into a lot of mechanical/electrical items in the car. Its difficult to do any swap in any of these cars.
Now I've seen a W203 C Class get retrofitted to a AMG, but never a W211.
The W203 C Class was a much simpler car and it was easier to perform this swap. There are even W203 55NA Motor Swaps into W202 platforms.

You could do it, but as other's suggested it would be cheaper to just buy a 63.
For a while I wanted the 63 engine in my manual crossfire over the 55K and after tons of research the cheapest motor I could find that was almost complete, was $20K...
That isn't the trans or the other 100 things you'll need to replace.
Believe me when I say I'm the first person to jump on the swap over mod or buy boat, but this case just would not be worth it by any means. You could probably buy a 63 (even though they're rare and expensive in your area) and mod it enough for a 1/2 second at least in the 1/4 with the amount of money you'd put into the 250. Plus your 250 wouldn't stop or handle the same....

engine cradle's are another thing to consider, i tried using a e320 body to do a complete "everything single thing" swap from a wrecked e55 and the front engine cradle mounts needed to be cut and repositioned to make it work, i ended up going another route, i would assume you would run into this even though you are talking about different cars/platforms... among a lot of other things.

sorry not a 320, this 08 e350 body was a 4-matic maybe that was the difference, im not sure which ones work and which ones dont exactly, the e55 cradle was a 05.

There are quite a few 63s with the MCT, and to me the $ value of that engine and trans has to be as much as the E250 is worth.
And as far as engine bed, who knows what donor car the 156 came from, we do know it was not a W211 cause they did get the 7G.
It would be interesting to see the diff and halfs disintegrate with the MCT launch.
