Thought some of you might wanted to see the difference between W210 stock 74mm TB and the bigger 82mm TB thats beeing mounted on my car this week.

74mm Vs 82mm


And the new port matched S/C inlet.

Old 74mm inlet


New 82mm inlet

Nice. Look forward to the update after install. GL
Btw- where did you source your 82mm tb from?
Thanks

Make sure you run a good gasket on that 82mm opening, there isn't much side wall left on that 82mm opening .

Nice work. I'm looking to do this mod this winter .

Very good Idea Magnus, is that 82mm TB from E/S/SL/CL550 #: 273 141 03 25..? if so,

what about the connector or the wiring.....??

And also all V8 M119.98xxx, 96 to 98 Engines uses 80mm TB, #: 119 141 00 25,.........

Remember: You need to modify the intake manifold (in the M113's) to use the 82mm throttle cause the bolt pattern are different (bigger), some people what to upgrade the stock throttle by a 82mm but this is NOT a bolt on...

But is a cool upgrade for the E55's

Hi!

Yes it's a 82mm TB from the new 550 models. Like Fabio said, you need to upgrade the intake manifold to make it fit.

But the wiring/connector is all bolt on, just plug and play At least on my 2001 E55.

Thankss Magnus, i think your stock (74mm) TB #: "113 141 01 25", the connector & pins(square Head) are the same in 550s (82mm) TB,,,

but mine #: "113 141 00 25", it has different connector & pins(Round Head), do you think it well easy to change the connector only...??

ZAYED,,

ABALONE

I think it's easy, it's only 2 pins that have to be changed when you switch the connector, at least what i've been told.

Do you have a F/I or N/A setup with your 82mm TB?

Good luck!

I just purchased an upgraded intake manifold from Germany for my c350 to allow the 82mm TB (273 141 03 25), I have the same 74mm TB everyone else apparently has (113....). Im trying to source one of the TBs in question, without paying the $800+ new from MB. Any suggestions?
So, also, it looks like the wiring is plug and play?? Anyone know for sure?

That's interesting,, is that company has upgraded manifolds, or can upgrade stock ones, any pics., i need to send mine to someone can upgrade it..!!

Thankss

Hi Magnus,

Do you try to put M273 Air Mass..!??, i think its also bigger than M113 Dia, but im not sure about the connector pins......?!?!

ZAYED,,

ABALONE

Hi!

No, i use the same Air Mass sensor from when my car was stock (N/A).

cm60k

Hi,

Thats fine, but i meant the M273 is bigger than M113 one, if possible to put it, that means another choice for the Air Mass & its good to have a big

Air mass with a big Throttle........

ZAYED,,

ABALONE

Aah, i think the M273 is oval? So you either need a oval platsic mass sensor holder from the M273 ot you just need to build a new bigger round one and fit the sensor in that one. Thats what i've done.

Hi Mag,

In your opinion;- is it possible to making a Y type adaptor & put "2" of M273 TBs....? if yes, what kind of Electrical connector needs to joint

the "2" TBs together...?? and is that well effect with air mass ratio voltage).....!!!

ZAYED,,

Fabio D

Not possible. I'm 100% sure the stock ME - ECU can't handle the 2 throttles to sit the idle of the car. & really is not needed 2 throttles in this engines :S try working in the exhaust system, port polish heads, port polish intake, k&n's or BMC's, Ecu tunes, pulleys, camshafs (pte or slr ones),headers, but 2 throttles = too much troubles for the gains

Thankss for that info. Fabio, i take this theory from all new M156 63s AMG, it uses "2" TBs, with ME 9.7 ECU,, if you notice; when Kleemann

puts there Kompressor in any of M113s; they uses a small Resistor to fool the Air mass ratio signal Voltage goes & return from the ECU.........!!
