Im thinking of a fun build of purchasing a 65 or 600 engine and put it in my cls. Im not sure if I am going to go through with it but time will only tell. What do you guys think?

Viet_Amg408

if you have the funds. anything is possible..

good project

Thericker

If it came from factory I'd be rollin in CLS600 right now! Def Doooo EEeeeettt!!!

will the v12 fit along with the 5speed tranny? It'd be great since you'll be rid of that jerky 7speed...

It will be a pricey swap but it would be pretty badass

joeybenz106

you would be putting the 5speed tranny in. just like in the brabus rocket.
tho you would have to do some mods the mounts and everything else.

RRnelcheeze

its fits in the rocket, so it will fit!

jikjak

is the 55 and 65 tranny different?
its always been a dream of mine to do that engine swap.

joeybenz106

yes they are different

beauphus

i considered this mod until i started getting pricing. very pricey project. good luck!!

As much fun as this may be, it will end up being a huge hole in which to throw allot money. I am in the tuning business and I think that there are better ways to spend money. It's about cost/benefit ratio. But if you have your heart set..... and have a big pile of money...

azncarjunkie

do it.

to the OP, the 63 comes with a 7 speed tranny. the 600/65 came with the 5 speed just as with the 55 supercharged engines. the reason for this is the 5 speed is able to handle the massive torque of the 600/65 engines. you would have to change out the transmission as well or somehow reprogram the 7. kleemann used to offer tranny modification programing for M113 500 engines that would be supercharged that had the 7 speed to handle the power or something.

Why are you doing this to a 63 instead of a 500 or a very very high mileage 55??

Gator AMG

This past Sunday I talked to a local MB performance shop about putting a 65 engine and supporting peripherals in the CLS55. He told me ballpark about $60K turnkey to do it right.

gaazmon

that's nuts. would be easier in a 55 than a 63 since tranny has to be changed (7 speed won't handle the torque).

cls55

is that for a new engine and trany or used one`s?very tempting

Both engines 65/600 are great engines. I would say do a 65 swap If you can. Remember you would need the respected ECU/TCU from the 65 or 600. The wiring harness, and a 5 speed transmission. It would be one heck of a build. You will find yourself becoming best friends with the MBZ parts dept. However if that doesnt stop you. You could really have something special in the end. I mean something I would expect to see at Barrett Jackson here in AZ.

gaazmon

you guys are nuts lol

would the 12 cylinder fit in the CLS hood since it is designed for V6/V8 engines vs the S/CL/SL are designed for V6/V8/V12?

why not just mod the engine with kleemann kits or something?

Forgive me for being the devil's advocate here

azncarjunkie

just do it. it'll be less than 60k if you keep it relatively 'standard'. 60k+ seems right if you want to go nutty with redoing the heads/block and custom tuning.

15-20k for a 600 engine/tranny
2-5k for electronics (if you didn't already get it from the donor car).
2-5k for a stronger drivetrain/differential

good to go...and you can sell that POS 63 motor to me.

gaazmon

lol i'd rather keep the 55 motor than get a 63. i love torque (and the 5 speed more than the 7)

DucatiGuy

It seems we have some rather ambitious individuals here... I for one, considering the high costs involved, couldn't rightfully justify such a project / mod. I mean it would be one thing if you're a tuner like Brabus, but as an individual on the consumer end of things, it's definitely a huge and costly undertaking. I personally also don't know if the gains in the end would be as satisfying, knowing outright the amount of $$$ and time that has been exhausted in the whole venture.

princemarko

A better project would be to bi-turbo the 63 engine.... thats a monster. Brabus did it and it really performs.

azncarjunkie

Brabus' turbo setup sucks on the ML. Other than being a cast manifold...the manifold only covers 6 of the 8 ports. Naturally they have to worry about reliability and emissions nonsense.

while 'neat', it certainly isn't a "monster".

CARNALE

Not trying to be ghetto but this day and age find someone trying to dump their 65 and swap the motor. Why would anyone in their right mind spend that much money to buy a motor that alot of people are trying to get rid of. Street smarts are good to a certain extent.
