Dennis, are you specifically talking about swap Engine to C43..??

ZAYED,,

KJI3jflarryfe93

yes that's correct, engine swaps from 4.3L ---> 5.4L .
put a 5.4L engine ---> into a C43 car

who knows i might do this mod in the future if i find a suitable donor and if i can afford it?


I have to write down everything so I don't fogget important information for future purposes.

My question was:
Engines up to MY2000-06 ME2.0/EGS51 are they plug and play in C43,
parts between both engines are the same without swapping TB, engine harness and fuel injectors?

All 98-00 C43's, got the early version of ME2.0 with EGS51, even with tiptronic shifter,

you can swap any 5.0l/5.5l "CLK/E/S", from 98 to 2002, with TB/harness/injectors/sensors, or using your exist TB/harness/injectors/sensors,,

if you want to put Engine from "ML" or any Engines from 03-06, you will have to re-use your exist oil pan..

the engine has to come from an W210 E55 AMG or w220 S55 AMG.
engines from CLK and ML has down rated HP which is no fun.

All 98-00 C43's, got the early version of ME2.0 with EGS51 - TB/harness/injectors/sensors which is compatible with MY2000-05 E55 engines.
This is only install, no swapping parts between engines

I don't think ML or CLK got a less HP, all 5.5l sharing the same out-put power,

the difference between C/CL/CLK/E/ML/S, are ECU/TCU software, and drivetrain Ratio's,

you can use any Engines 98-2006 from any models, but you have to use your ECU/TCU to fire it up & matching your exist sensors order..!

I understand I can use an engine from various MY to mate this with my C43 ecu/tcu.

My question was:
If I find a donor engine from MY1998 to MY2000-06, from these MY engines I could DIRECTLY use their engine wireharness, fuel injectors and TB without having to take these parts from my C43 engine and putting them on the new 5.4L engine??
My C43 engine is a 1999 and the donor engines came from MY1998 to MY2000-05 they share the same ME2.0/EGS51 system with my C43.

If I find a MY 2000 engine then I want to use the hardware parts from 5.4L engine instead of using the C43 parts because they are 1 year newer and maybe updated on 5.4L engine:
TB - wireharness - fuel injectors must have the same plug connectors like my C43 which must be directly plug and play fitting engine into my car?
This is what I want to get confirmed?
I wouldn't buy an engine from 1998 because it's older than my car, it has to be at least an engine from 1999 -------->

When everything is put in place, then everything has to be reset to ZERO with STAR, drive the car to adapt every settings, check with STAR again for possible error codes, if no codes everything is OK?
there shouldn't be a problem if I chose not to re-flash my ECU with snake oil E55 software sold from shady tuning companies?
5.4L engine should work perfectly with C43 ECU, not getting lean A/F mixture, not getting rich A/F mixture?

ML/CLK had 347HP on paper because E/S-klasse was more luxurious.
I think MB downgraded ML/CLK a few HP for marketing purposes?

When dealership were selling these cars, customers might would have asked why does the E-klasse have the same HP like ML/CLK and both were probably were cheaper priced cars?
Customer would have bought the cheaper car getting the same HP, but I could be wrong?

I believe this was only a marketing thing to boost the E/S-klasse cars in the upper luxury class with other brands from Audi and BMW.

If you want directly Engine for you C43 with everything(TB/harness/injectors/sensors), you have only get Engines from (99 to 00),

if you go with (01 to 06) Engines, you can use injectors/sensors ONLY, can't use TB/harness, they are differ than yours,

you have to use STAR/SDS to see everything is OK, and ECU reading everything properly, drive the car a little bit, then use STAR/SDS again to confirm no any codes appears,

No need to flush or program the ECU, unless you want to tune it, it's a differ thing..!

it's not that difference between 347hp & 354hp, only for, as you said; just marketing & advertising..!!

ZAYED,,

KJI3jflarryfe93

mashala my brother.
now you confirm the information I need!
only to go with 99-00 engines for direct swap without taking parts from my 113944 engine fitting to 5.4L engine.
this is the easiest way to do the engine swap when both engine use same parts for TB/harness/injectors

thanks

Just so I'm 100% clear on this, I'm unable to use the throttle body and wiring harness from an '02 E55 motor when swapping out my 4.3. Correct?

cm60k

Yeah, usually 02 Engines uses a differ TB/harness,

prefer to check the TB in 02 E55 Engine..?, maybe previous owner change it or something..!!

ZAYED,,

nkctb7

Thanks, Zayed! The motor has only 100K Kms. Everything including the coils and plugs are original.

nkctb7

Hey PJ,

I was wondering what the solution was that you used to powerwash the grease off your 55 motor? Cheers!

PJmak

It was a regular car wash. Just selected the engine wash option.

I had the valve covers and oil pans hot tanked later

nkctb7

Thanks PJ! I suppose with the engine out one doesn't need to worry about using a powerwasher on an engine. Did you replace the head gaskets as well?

Thx

PJmak

Didnt do the head gasket. We taped off all the holes before the engine was power washed

blackbenzz

If anyone wants new Mercedes head bolts I have a set I'd sell for 100 bucks

nkctb7

I'm told that replacing the head gaskets is probably overkill as AMG head gaskets are bulletproof. Thx

nkctb7

By the way, your engine looks stellar! What parts did you replace before dropping it in?

PJmak

It was in pretty good condition according to my friend who did the swap for me.

I replaced:
-rear main seal
-valve cover gaskets
-water pump
-thermostat
-belt tensioner
-sparkplugs
-oil pan had to be swapped of course
-c43 wiring harness had to be swapped
-oil cooler resealed

cant remember what else

I didnt go all out on it as you can see.

I should have done the timing chain because it sounds a bit loud and theres a slight knock at cold start up that goes away once the engine warms up a bit

nkctb7

Thank PJ. Those are all the things that I'm replacing, including the timing chain. The engine I picked up only has 100K Kms. but I don't know the history of the maintenance on it. I'd rather be safe and replace it while it is out. Are you running headers at all?

PJmak

Nope all stock for now. Cant wait to do something to it.

I want it to sound nice. I really dont know what to go with. I havent seen anything that sounds different. M113s soumd kinda old school imo

I want it more raspy.

Im just absorbing information for now since i cant afford any of the mods id want. Id want a nice set of custom cams just for the sake of changing the sound.

As of right now im not sure if its worth it....still reading on it and informing my self for now

When is your motor going in?

nkctb7

I went with the Eisenmann race muffler and had the secondary cats deleted. I'm getting custom headers made with an x pipe installed. I'm debating whether to have the resonator deleted as I don't want harsh droning.

nkctb7

Can anyone recommend the best way to remove the aforementioned freeze plug? Thx

sick430

Nice choice in engines. the MLs actually produce a little more torque as the cams are slightly different. I also like to believe that they are less abused over the c/clk/e engines.

KJI3jflarryfe93

wud you say a w202 with an ML55 engine wud be faster and produce more turk than a w202 with an E55 engine?
