Looking for a CLK AMG 5.4 motor, must be verifiable low mileage. would consider a E55 also. I am very sceptical of on-line salvage yards that every motor they have is 64K miles.
Also if any of our So Calif members have done a swap or know of a shop who has done a swap I would appreciate that information.

Thanks again for any info.

Why a clk motor only?

hey. very simple to see mileage from salvage yard.

ask for the VIN number from the car. once you have the VIN, check this site here:

https://www.vehiclehistory.com/vehicle/land.php

click continue at bottom of page after entering vin and should tell you all of the miles

here is the vin off the engine i bought, you can see the auctioneer reported the miles before sale to the yard. you can also see that in 2007 it only had 25k miles.

What about a 2006 C55 5.4 motor with 112K miles?

mkoons

From my limited knowledge I believe the CLK55 & E55 swaps require the least modifications. The torque range on the CLK was more mid-range & it had the most hp.
I am open to suggestions as my knowledge is only based on what I have read on the forum.

Does a 2006 just drop in & mate up-to the trans? I thought 2003 was the latest year that was plug & play.

clk 2003+ is considered the EVO engine. it has different cams and stiffer springs. it will fit, you just need to swap the oil pans, TB, etc. check out the swap thread.

also so you know it looks like all the 5.4 are the same, e55, ml55, clk55, etc. we are guessing that the diff power ranges had to do with exhaust/tune. the evo engine probably produces more HP than the pre-evo engine. also i read that because evo has different cams it may need a tune to get the best power but i cant confirm that. the theory is that c43 can run stock tune on any 5.4 pre-evo because all the engines use the same cams including c43. but again thats only what i read on the board here and cannot confirm it.

all that said, evo engines are pretty cool!

Sure, any "M113 4.3l/5.0l/5.4l" will fit perfectly, just need to put your "oil pan/oil pump"..

Definitely correct Mickey, C43 sharing the same timing angle with 5.4l, "ECU/cams"..

if the engines are, in fact, different between E, CLK, S, then the E55 would likely be the best fit for pure power due to the highest torque figure.

however, it's been said by lots of folks that the motors are actually no different at all. the only thing differentiating them is the cars they are in and what this means for the exhaust system. the engines all have the exact same internals and should make the exact same power. but they make more hp and less torque in a CLK, less hp and much more torque in the E55 and S55 due to the straighter exhaust paths.

I can't find anywhere an official AMG figure as to what the w202 C55 put out, but it's likely very very close to that of the w208 CLK55 being similar lengths and exhaust.

I may have that info in some old files hidden away in a corner. Let me check tomorrow morning and I'll get back later...

Well with the new info on these "evo" engines emerging If I was you id just get one of those.

Those would come in w203 c55s, w209 clks, and the slk55s I believe.

I think its common sense that a m113 engine will produce different figures when hooked up to different cars ecus. Im pretty sure each car was tuned certain way.

Having different exhaust setups also contributed to the results from the ecu tune and if you look into it most of these cars....at least 98-2002 have different exhaust setups. For example an E55 has a different exhaust setup from a c43 and clk55.

It would also make sence that the evo engines have more potential if in fact they do have a few differences in design.

Get an evo engine and hook it up to your stock ECU. You might get the most out of it you never know but you might be loosing some power due to the way the c43s were tuned.

Either way im sure youll end up slapping some headers, exhaust, and intake mods and will want a custom ECU tune

cm60k

Yeah, you're correct,

AMG put 5.4l from W208 Clk55 officially for sure,

have 3 friends with original W202 C55, when i put their Vin #, Engine comes from W208 Clk55, "113.984",,

i Emailed AMG around 4 years ago;-

they confirm to me 100%, they officially put W208 Clk55, Engine into W202 as an upgrade from (4.2l to 5.4l)..

;ZAYED;

cm60k

*in Germany; they upgrade their M113 "head/intake/gearbox/headers/ECU remap", on many models, that was in "Nürburgring drift cup",

they called it "evo/SR",

*in Japan; they put M113 Engine assembly from "Slk55 Black series" in W203 C55, on "Japan RC/44 drift",

they called it "CR/M113 SS evo",

that's the only info. i know about "M113/evo",,

if anyone got more info., pls. light it up..!

;ZAYED;

DRBC43AMG

As promised I searched around in my files and found the info and some more from a Wikipedia document dated 2010... Happy reading!
The W202 C43 AMG upgrade program to make the C55 AMG was called "AMG Specials".

General specs:
The C55 was rated with 345ps (254 kW) at 5'500 rpm and up to 510Nm of torque starting at 3'000rpm-4'300rpm. Red line revs was fixed at 6'000rpm. The upgrade included a new gearbox and overall transmission. The updated instrument cluster bears the AMG logo and a 300 km/h scale card. Only 45 units of the W202 C43 AMG were converted to C55 for a price of around Euro 30'000.-.

Engine specs:
The engine block is coded M113.983
The cylinder heads, crankcase and cylinder head gaskets come from the 5.0 litre M113.961 engine
Crankshaft, pistons and connecting rods are new components manufactured by AMG
Re-designed camshafts with cams specially designed for the engine
Valve seats taken from the M113.961 engine

Transmission:
The transmission is the 722.636 5 speed "Speedshift" taken from the W208 CLK 55

EFI:
New controller (ECU) using a Bosch HMS 7.0 unit with modified data settings for extra power output and optimum exhaust emissions

Exhaust:
Except a new middle and tail silencer, the upgraded C43 uses the same exhaust system

Rear axle:
New rear enlarged axle housing with 2.82 ratio with new driveshafts
New rear axle wheel flange
New propeller shaft with 4 arm flanges 110mm

Floorpan:
Modified under the rear seats to accommodate the larger rear axle housing

As a reminder, the W202 C43 AMG was manufactured for a little more than two years (end 1997 to spring 2000) for a total of 4'200 units with a ratio of 80% saloons and 20% estates.

Any info on specs for a factory W202 C55 amg?

DRBC43AMG

All the info is in my post above, not unless you are talking of the W203 C55 instead of the W202

Here goes then for the W203 C55 (from Wikipedia):
Along with the mid-generation refresh of the C-Class in 2005, the C 32 AMG was also replaced, giving way to a new 5.4-litre naturally aspirated V8-powered C 55 AMG. This was an evolution of the V8 engine found in the previous E-Class, with power raised to 270 kW (367 ps) and torque climbing to 510 Nm (376 lb/ft).

The C 55 AMG uses a V8 from the same engine family as the W202 generation C 43 AMG. Though maximum speed is still limited to 250 km/h (155 mph), the 0 to 100 km/h (0 to 62 mph) time has dropped to 4.7 seconds.[12] Unlike the less-powerful V6s in the rest of the Mercedes-Benz line-up, the C 55 AMG continued to use the five-speed automatic with AMG Speedshift. The C 55 shares its longer front end design with the CLK 55 AMG to accommodate the large 5.4-litre engine. The C 55 AMG is the only AMG model to feature different structure than its base Mercedes platform.

The C 55 was the first AMG C-Class to feature quad exhaust outlets and an external differential cooler. The Nürburgring Nordschleife lap time seen on List of Nürburgring Nordschleife lap times for the C 55 AMG is 8:22 compared to 8:37 for the C 32 AMG mainly due to the revised suspension and extra torque. The C 55 was mainly sold as a sedan with a portion of wagons being sold in European markets.

202C55 has the "one-off" .983 number, its only difference to clk55 .984 is right side water pipe for trans cooler, the CLK55 has it combined in the radiator.

The .636 trans was not only touchshift , almost all genuine C55 I see are gate shifted including the one we have here.

The hype about which parts were selected for the C55 engine is for sales pitch, they are standard parts for all the ~98-02 5.4.

prop and rear axle setup complete are 100% clk55. boot floor is beaten up with hammer and dolly by amg to fit the diff(Clk55 has a weld in raised portion for this,it is 98% 202 after all!)

Centre silencer same as clk55, rear siliencer custom for the C55(same as clk55 but tips lower and muffer body not cut for clk55 bumper)

Ecu tune will be same as clk55, I tested the 00C43 ecu excepts clk55 coding and are same ecu part number. don't try it on 98/99 though.

mickey13

i believe there is another w202 (one off made to order) made by AMG Studio that has the new EVO engine and produces 400 hp.

found info on another forum by someone who seemed to be in the know that stated this car was registered by AMG.

Sulaco

That translates to w202 c55 only having 340 hp and 374 ft lbs of torque. Yuck. The weakest of all 55 cars!

All I know is that no matter what year C55 ,CLK55,older n/a S,SL,CL,G,SLK ALL

the n/a 5.5l cars I have seen here on the forums that most have dynoed from 285 to 295whp regardless of year So I mean am I missing something

This Evo thing seems like big hype. Seems like all one would need to do is

change to the later year cams and valve springs get a tune but will it really be

worth the $ and trouble going for the theoretical les than 10hp increase? All I

know is that I still Dyno stock the same as all of these cars. Last Dyno with mods

327whp. Just get your cat back exhaust done and that really wakes up the 5.4lliter engine for cheaper and way more than just the different cams and springs.

If anyone wants to make a major investment I say start looking to drop in a 55 kompressor motor. cheap now and a dime a dozen perhaps way more out there available compared to the N/A motor and with lower mileage. Right there I'm talking bang for the buck.

The newer NA mustangs and Camaro ss are 400+hp and will soon be close to 500hp I predict in the years to come. So everyone who wants to compete like me for instance will have to step up to the sc motors.

PJmak

Like someone above said, the upgraded parts maybe distribute and manage power better which means maybe better torque curve

Im not an expert but it makes sense.


Those new cars will also keep gaining weight btw


I am yet to see someone extract every possible pony out of a n/a M113. Throw 15-20 grand at it and see what happens .Im talking custom intakes, exhaust, tunes, cams...you name it

ProjectC55

Ni8Before I were to throw 15 20k into this motor NA Im going SC for less than a fraction of that 20k and have more hp than you could reliably extract from the 5.5l NA. You are not going to do better than the 5.5l SC Motor nor the new DOHC 5.5 l biturbo V8 with the 5.5l normally aspirated. PS try racing the new 2k14 to 2k16 5 .0l mustang GT and you will get the surprise of your life topend!!!! My friend has an auto and runs low 12s with drag radials at 118mph. Also the present valve train can deal wth bigger cams and higher rev limiter no problems. These cars are over engineered. Ever ought out why you have a c280 diff connected to your 5.4l v8 and deals ith the 391ft lbs of torque quite well.

Does this statement apply to a '05 C55?
