I'm trying to find out which model of Mercedes (SLK55 maybe?) engine the SRT has in it.

 

All AMG 3.2s SLKs. Cs and Es.

 

Close...The engine is the AMG-spec'd supercharged 3.2 liter used in the C32 and SLK32 AMG models. (E class runs the 5.5 liter)

 

I think they used to use the 3.2 AMG in the older Es too.

 

The SC'd 3.2L was only used in the SLK32 & C32. The NA version of the 3.2L was in most of the model lines from MB. The older E55 ran an NA 5L (or maybe it was a 5.5L). The newer E55's got the SC'd 5.5L.

 

The SC 3.2 liter is better known as the Mercedes 112.960 engine.
It was used in the SLK32 (170.466 chassis) from 2002 to 2004.
The C32 (203.065 sedan and 203.265 coupe) used the 112.961 engine (supercharged 3.2) in the same years.
It's essentially the same engine with very minor differences to fit the different chassis.

If you look at your engine cover and other parts, you'll notice that most of them start with the number 112.
The radiator is a 202 part that was borrowed from the 202 chassis (1994-2000 C class chassis).
Mercedes has an interesting part numbering system but it makes it easy to identify parts.

 

The coupe never was offered with the supercharged 3.2 liter. Nearest thing was the C 30 (3.0 turbocharged diesel) AMG Sportcoupe that was for sale outside of North America. Engine choices for the coupe in the U.S. ran from 2.3 L supercharged in the beginning to a 1.8 L supercharged after they phased out the 2.3's. The N/A 3.2 was also an option in the coupe.

 

I think the SRT6 3.2 Benz engine is now exclusive only to the Crossfire here in the states now!

 

Yep C32 moved up to the C55 along with the SLK..

 

You're right. I wasn't paying attention and screwed that up. The 203.265 was the C32 wagon. The coupe was not available but the wagon was produced in limited numbers. It was equipped with the supercharged 112 engine.
The C320 was the non supercharged 112.946 engine.

The C30 was an AMG car with the 612.990 diesel. Most Americans would not find that amusing so it was never offered over here.


BTW... the C230 now comes with the 272.920 V6 instead of the supercharged 1.8 L four popper and the C55 uses some of the front structure from the CLK to fit the larger engine. It's a couple inches longer than the other C-class sedans and has front sheet metal unique to itself.

 

It's too bad that you can't e-mail the engine assembly (AMG) plant in Onsnabruke(?) to get the missing signed assemblers plate that all the regular AMG-Benzes have in that blank spot on the supercharger faring...Maybe that's why the car comes with the downscale non-AMG engine cover...they think that you won't think to look under it and wonder!!!

It's SLK320 for the Crossfire and Crossfire LTD. SL32 AMG for the SRT-6. If you compare the interiors (dash board, console, etc.) of the SLK320 and SL32 AMG to the Crossfire, you will find them virtually identical.

 

slk 32 amg is the car that had the supercharged v6.

 

Yes, that's the one...

 

What total crap is that at the DC "Inspired Drives" events they have an actual SRT-6 engine on display ... WITH the plate! Have pics to post if i can figure out how to reduce the image size, shot with an 8 mp digital slr so image size is huge.

 

I've tried multiple avenues to get a new plate for mine since I acquired the car to no luck...only other option is to use one from a parted out AMG but, of course, the sig. on the plate will probably not be the person who also built our engine...
