Hi Guys,

I Have a 2015 mercedes E400 W212 (specifically the J-Spec M276 3.5 bi- turbo), so far gettings parts for this model has been slim to none, I can confirm that even though it is not listed the BMS Dual intakes work, below are my mods thus far:

1. Eurocharge Stage one tune (rated at 480HP) soon to be stage 2
2. BMS dual Intakes
3. custom fabricated down pipes (not yet installed)
4. FI Valvetronic Exhaust (not yet installed)
5. Intercooler (which i am having problems with and hoping for assistance if possible)

For number 5 I see that there are 2 possible choices which is a Wagner or CTS intercooler.

For wagner it list the below compatability for the M276:
Performance CHARGE AIR COOLER KIT Mercedes Benz C / E / GLC 43 AMG is suitable for the following models:
Mercedes Benz W/S/C/A 205 C400 4MATIC 2014-2018
Mercedes Benz W/S/C/A 205 C450AMG 4MATIC 2015-2016
Mercedes Benz W/S/C/A 205 C43 AMG 4MATIC 2016
Mercedes Benz W/S/C/A 213 E43 AMG 4MATIC 2016-2018
Mercedes Benz W/S/C/A 213 E450 AMG 4MATIC 2018-06/2020
Mercedes Benz X/C 253 GLC 43 AMG 4MATIC 2016-2022
Mercedes Benz C 292 GLE 43 AMG 4MATIC 2015-2022

For CTS it list the below compatability for the M276:
Benz C Class W205 (2015-2021) C400 M276 3.0L
Benz C Class W205 (2015-2021) C43 AMG M276 3.0L
Benz C Class W205 (2015-2021) C450 AMG M276 3.0L
Benz E Class W213 (2017-2023) E400 4-Matic M276 3.0TT
Benz E Class W213 (2017-2023) E400 M276 3.0TT
Benz E Class W213 (2017-2023) E43 AMG M276 3.0TT
Benz E Class W213 (2017-2023) E450 4-Matic M276 3.0TT
Benz E Class W213 (2017-2023) E450 M276 3.0TT

Do you think the above intercoolers would be compatable by any chance?

Though parts may not be specific per the E400 W212 alot of parts are interchangeable/compatable.

Thanks

Where are you located?

It would be interesting to see if Weistec could upgrade your turbos? What is the complete model number for your car?

Mafioso345

Hi I live in the Caribbean.....see attached. Not interested in upgrading the turbo's because im pretty much at the limit of the engine with the mods i would like to do on this bad boy, however I am curious about the M276 3.0 vs 3.5, from research the 3.5 has much lower boost than the 3.0. also any thoughts on the intercooler compatability with it?

Mafioso345

sorry meant to quote you see above.

The interesting thing is we have the same transmissions. I've always been a little concerned that a tune might damage it. My tune takes me to about 420hp.

Mafioso345

You also have an E400? Depends on the amount of torque they can handle, MB says 500 but research indicates higher i believe, cant wait to install my other mods, my exhaust just arrived so hopefully next week i can get the exhaust and DP's installed....

No, I have an SL400. You should follow the postings of @S-Prihadi who has an E400. Want a free mod? Unplug the oil pump solenoid.

thanks bud

I think the easiest way would be to look on the EPC whether the W213/W205 intercooler part number is the same as the one used on your engine. If it is, there's a very good chance the fitment will work.

Mafioso345

Good idea, lemme head over to car ID

Mafioso345

They Actually match up:

I could not find the intercooler in the EPC when looking in any of the logical places, AIR CLEANER AND ENGINE CHARGING or INTAKE AND EXHAUST MANIFOLDS. But using the part number for the IC from the links you provided, I found it in the Group 50 RADIATOR. What the heck?

By the way, it's the same part number for my SL400.

Mafioso345

Yeah i think there is alot thats compatible across all models with the same engine, I ended up getting the CTS intercooler because the guy said he is 90% it would work and also gave me a 15 percent discount, for wagner their customer service said they also thought it would work as well.

Ill let you know how it goes, I ordered it and ill go get it closer to end of month, in the mean time i have my FI exhaust, custom downpipes and stage 2 eurocharge tune to add till then

Mafioso345

hey Jetta i was thinking about this, does this mean that the standard turbo m276 3.0 replacements would not fit my m276 3.5?

JettaRed

iTrader: (1)

Don't know. I'd call Weistec. Your car is spec'd for Japan. I don't know if the parts are interchangeable as far as fit is concerned, but the part numbers for your turbos are different than other E400 3.0 liter.

Caribbean is a tropical region. I am a bit hotter than your location, say by 3 - 4 Celsius.

Do watch out for coolant temperature when you do those power up mods.
Our E400 cooling system is NOT so good when driven hard in a tropical country. Your 3.5 Turbo boost is lower than a 3.0, hopefully standard as is the cooling sytem, it is cooler when modified.
A member who is also from Jakarta-Indonesia done some mod to his CLS400 same engine as mine 3.0 Turbo to be like 400HP there about and his radiator
is not sufficient to dump those heat, when and if driven hard.

My own standard 330HP, all I need is decent hard run 2 laps at 34C, on a 4.1 KM short track, 120C coolant temperature,
1st is decent hard lap by my friend 118C coolant, 2nd is pit stop driver change to me and a slow cooling down lap, 3rd is my lap, I push a bit harder....120C coolant temperature already




.....

I do not see suspension upgrade on your list.
If your suspension is standard SACHS , get Bilstein B4 for the front and B6 at the back, no need B6 at the front. No need sport coil springs.
If your damper is still standard, it is no fun swiping a long mild corner at 180KH/H or faster with SACHS standard dampers....it is downright awful and scary.

Surely ultra high performance summer tire suits your climate, just like mine.
Since you are on an island country, I think tight S bends are plenty, get a rear DIFF, Automatic Torque Biasing (ATB®)) type, no need clutch type.... you will gain better traction A LOT in those
super tight corners.

Get either WaveTrac or Quaife

Awesome read man, thanks for all the info, I live in the Cayman Islands where the top speed limit is 50MPH, I just wanna give her a good squeeze every now and then, Ill send a pic shortly and you let me know if you think i should lower her more, she is stock height but i was also thinking about dropping her more, do you have a link to the suspension and also do you have pics of your E400? how does your car feel after unplugging the solenoid? You and @JettaRed have been great in giving me info, thank you guys apprecciate it....

Mafioso345

Hey bros @JettaRed and @S-Prihadi would this pretty much be the same as our engine capability? are internals different from regular m276 vs a amg m276 or is it just a tune?

S-Prihadi

C43 engine also a 3.0 Turbo, but the engine model number is M276.823, its turbocharger is different P/N compared to my M276.820 3.0 Turbo.
Some other parts are different too but I do not know all of them.

I think yours is M276.850 being a 3.5 turbo. Your chassis code is W212.061 yes ?

I will not lower my car, it is LOW enough for my crappy road.
I believed I get the 15mm lower suspension version because of the AMG Kit I get original version by MB Indonesia.

Suspension : Front and rear Bilstein B4

Bilstein B6 rear only the rear ones, front still a B4 , user experience

Bilstein B4 all 4, fun at the track. All 4 tires bye bye and stabilizer link torn and suspension arms needed correction bolts....all within 20ish laps.

Actually even ALL 4 of my damper bump stops were consumed too from such short track session.

I have very few photos of my car, but I got 10,000s of photo of me working on it, bolts n nuts, components...A LOT.

These 2 are the only proper photos.

Maf,


Me not intending to be rude. but this air filter arrangement is HOT AIR INTAKE , not good for the engine.

The original air filter ducting system uses the positive cold air from OUTSIDE the car when at speed of approx 20 KM/H or higher.



Typical sedan front part and the air pressure from moving air. We want our engine breathing air to take outside air and at its highest pressure.




The air intake system because it is not under pressure ( before turbo ) , plastic is a good choice as it is heat insulator ( sort of ).
Using metal will make it hotter in engine bay.

Why don't you get a good OBD2 data logger, and log your intake air temperature. I am using Banks Gauge iDash.
Log the Intake Air Temperature.

Here is engine bay ambient temperature for us in the tropics.
My K thermocouple sensor is at the LEFT side of the aftercooler if we seeing it from inside the car.






Have a read here : https://mbworld.org/forums/e-class-w...e-project.html


Some data.....

Specific to my engine M276 3.0TT ( M276.820). The aftercooler works best past 80KM/H too in my tropical country with average ambient temp 30C and my city bad traffic.
This test run is 10PM and not at traffic jam yet. IAT can be as high as 60C at bumper to bumper traffic.



.





.
The moment we stop our already running engine ( say 1+ hours engine running ) for fuel and coffee, say 15 minutes, the heat soaked to engine bay components are insane.
The cooling down of the heat soaked components need time, like 20 minutes or more when at 80KM/H or faster.



===========

We in the tropics already lost power EVERYDAY because our ambient temperature and humidity is not cold and dry enough to meet SAE Standard Horsepower atmospheric condition.


This is Turbo GrandPa..... Mr Gale Banks, watch his great videos on turbos and temperature


.


My engine can never be 100% power output in my climate, unless I go up the cooler mountain , but I loose atmospheric pressure boost while at it ...LOL.
It is what it is, physics, we can't escape it.


https://dynomitedyno.com/tech-corner...ed-horsepower/
The older J607 standard considers that the engine was run on a 60°F day with 0% humidity and a barometric pressure of 29.92 in-Hg or the newer SAE J1349 standard of 77°F (25°C) day
with 0% humidity and a barometric pressure of 29.234 in-Hg (99 KPa). Also the ECE standard is the same as the SAE J1349, but does not use mechanical efficiency in the calculations.

The DIN standard which corrects to 68°F (20°C) day with 0% humidity and a barometric pressure of 29.92 in-Hg (101.3 KPa) and
the JIS standard corrects 77°F (25° C) day with 0% humidity and a barometric pressure of 29.234 in-Hg (KPa), but uses different correction curves than the others (as a substitution for using mechanical efficiency factors).
Further, we have the J1995 corrects 77°F (25° C) day with 0% humidity and a barometric pressure of 29.53 in-Hg (100 KPa).



Have fun...........

Yeah thats why i gold wrapped them to reduce 80 percent radiant heat, maybe down the i can change to mst intakes, but the sound is so much better lol, thanks for the info as usual though.
