Which Mercedes motor do we have? I have seen SLK 320. I'm guessing that SLK is the body style and 320 is the type of motor, but I'm not sure. I'm far from a Mercedes expert, but there is a Mercedes plant in Tuscaloosa Alabama, and I have a friend there who I need to ask some questions, and don't want to look stupid with some basic questions... So I'll just look stupid in this thread. I will post all any good info I can find from him.

 

we have the 320 that is in the slk... and something like 80% of car... is MB... something like that!

 

It is the Mercedes 112 engine ?

 

From the factory sticker:

Parts Content Information
Major Sources of Foreign Parts Content:
Germany: 80%

For Vehicles in this carline:
U.S./Canadian parts content: 1%

Ok, that accounts for 81%...they forgot to tell us where the other 19% came from...I wonder why? Sounds like a conspiracy to me...

 

The remaining parts are from Mars, that's why nobody can figure out how to build performance products for the car.

 

I believe the rims are from Poland.

 

Too true.
lol

 

Close, real close. The W112 was a car built in the late 50's if I recall correctly.

The W signifies sedan such as a W210 ('96 to '02 E-class).
It's a 112 motor. I believe it's a 112.981 variant or later. The 112.961 and earlier motors had a different ignition system (and a few other things).

MB Likes numbers. Those friggin German engineers must engineer everything! It's almost like they're obsessive/compulsive or something.

Mercedes issues engine, transmission, and chassis numbers that look like an old VIN.
112.198.12.058736
112 = type of motor (3.2 liter V6)
981 = engineering variant
12 = automatic tranny (10 for standard)
058736 = sequence number to identify this engine (but I just threw 6 digits at random)

722.6xx.xx.xxxxxx for the transmissions in these ( 5 speed auto)

170.449.12.165540 Chassis number for a 2003 SLK230 Kompressor
170 = SLK model
449 = 2002 or newer 230 Kompressor variant
12 = automatic tranny
165540 = production sequence number

WDBKK49J47A165540 VIN number for above SLK
WDB = World Daimler Benz (most cars except ML, R, G, CLS, and SLR)
KK = SLK model
49 = 2002 or newer 230 Kompressor variant
J = drivetrain layout (if I remember correctly)
4 = check digit
7 = code for year produced
A = Sindelfingen production plant (which is obviously wrong for the SLK but I don't remember what the digit is for Karmann)
165540 = production sequence number

 

So SLK320 for engine & trans. How about suspension parts? I have been told SLK32 parts will fit. I want to upgrade some items.

 

The only suspension parts that would be an advantage to swap from the SLK32 would be the sway bars. The springs and dampers are swappable, but you should look at better after market parts. Eibach, K&W, Koni if you want to get the most bang for your buck. Also get thinner perch pads for the springs.

 

Thanks. Are those aftermarket Sway bars or Mercedes OEM parts?

 

Mercedes OEM for the SLK32. More preload, solid vs hollow and 2mm larger in diameter.

 

Thanks. So you have the size of the stock ones handy? I searched for it for it was posted a while ago but missed putting my finger on them.

 

I posted somewhere. Try searching srt6 limited specs. Or do a search on the posts I've made... It was probably 9 months ago.
