Bump a probably old thread but my swap should be done soon and im down to race a stock w203 c55...
C43s can be very fast but the tranny is a major bottleneck. It needs to adapt to fast shifting. I pulled on a w210 e55 from a roll by half a car length in mine, hung with a c32 pretty damn good, and murdered a ml55 off the line.
People underestimate the c43. Its pretty damn fast for what it is especially from a roll

C43- 3461lbs/302hp= 11.46lbs/hp
C55- 3540lbs/362hp= 9.78lbs/hp
E55- 3768lbs/349hp= 10.8lbs/hp
It's pretty simple. A 5.4 swapped C43 would weigh almost exactly the same, plus be up 50-60hp. That gives it a slight edge over an OEM C55. .01 difference in gearing means nothing. Due to its lighter weight, the updated m113 would suite it better. +15hp -15tq? Please and thanks. HP>>>TQ as long as you have the rpm's and gearing to compliment it.
The "exhaust pipe length making a difference in power" was pretty funny to read. +30 hp to a Viper, sure, not new heads/cam...
Now that it's 10 years latter, can we please call them the correct engines for newbies like me. The 5.4SOHC and 5.5DOHC. Unless of course, somebody is swapping a near 400hp monster up in here

I thought all m113s were exact same motors. The difference in power is simply because of a tune mb used. Of course you have different oil pans and a few other bolt on parts
the motor i bought is out of a 2002 ml55

No way is my guess. The peak rpm's are a good bit off, and if they could have ekked that extra power out of them, they would have.
I've tried finding differences online and literally found nothing. It blows my mind. The later one's have a split runner intake to get more top end power. I'm guessing the old ones don't, and probably minorly different cams to match.
The original ones were meant for all heavy cars and SUV's(and torque is easier to make then hp). Once they switched to SC'd motors and only the lighter C/CLK had that motor, they didn't need as much low end and could focus on making higher(ish) rpm HP.
That's my guess.

Well, I've did this with my 202 C55 against my buddy w203 c55 and theres no comparison I blew his doors off .
Only difference is his car is stock
I had E55 ported polished Kleemann long tube high flow cats
Kleemann tuned
Renntech carbon air box.
I,m now building aW203 c55 supercharged.

With my brake conversion we weighed all the old components there was a 120lbs difference I never got a chance to weigh the car before and after.
I just know my buddy was not very happy ......

Yea theres a slight advantage there lol no surprise you owned him.
W203 c55 is a fast car and i cant wait to race it.
Again if anyone is local (sac town/bay area) id love to race once my car is done. Ill be completely stock with a 02 ml55 motor and a 01 e55 trany with the ecu tuned to the spec of a 5.4 motor

1999 Mercedes C43 AMG, 2002 Mercedes S600
I think the w202 would be faster. I swapped my 1999 c43 with a 2001 w210 e55 engine and took it to the dragstrip. Only modification that was made during my pass was that I removed the air filters out of the induction box. The car ran consistent 13.043 and 13.069, but by the end of the day i was able to pull off a 12.973.

I did my swap on a 2000 C43 with 2001 E55 motor and trans no tune I ran my buddy C55 and walked away C43 had headers and ported heads
Second run gave him a head start and still caught up to him.
