Just bought a project, a very rare Mercedes 190 amg 3,2 -93
One of the few cars produced by Mercedes with amg technik package code 957
m103 amg 3,2 engine ,manual dogleg gearbox, and all other special amg parts for this model.
The car wasnt ordered with the special amg aero package thou, would be cool to have that 😁
Anyways, too the questions I have.
I bought the car as a project car, there is some work to do on it.
Body and interior is ok but engine is in pieces and need to be put together again.
I have all parts and everything amg is there and correct.
But I wonder about some stuff
Anyone that has information or partnumber for headgasket for exampel, guees its a special one considering the larger bore?
Also if any one knows if its stock valves in these heads or its some special amg parts?
Maybe someone here that have refreshed their engine amd have some good information for me?
Sweet! Maybe post a picture of the car and the engine for us please. Is this a 12V 3.2 engine? If so, it is indeed rare and probably needs a special head gasket.
Given the engine difference for your car, I'm inclined to agree with Dolucassi for the head gasket. There will likely be other parts differences as well. I would suggest that you check with the MB Classic Center on the differences between your car and the more typical 190 versions for parts since your car is such a rare 190 version. The MB Classic Center is an invaluable resource with a very deep reservoir of knowledge about the 190 model in all of its varieties. I think it's great that you're working to get such a rare 190 back on the road. It's value is in its rarity so be sure to keep it factory original. Any mods will lower its value because originality in MB world and especially for rare models is key. We'll be interested to follow your progress. BTW, we do like pictures around here so a picture of your car would be great.
Sounds like a super project. Let us know how it turns out with the Head Gasket search. The cylinder-cylinder spacing on the 3.0L M103 is super tight already, I'm wondering if AMG somehow magically increased the stroke and did not change the bore diameter, thus increasing the compression ratio. You should look into that and if the head is taken apart measure the bore diameter. You may get lucky.
Good question Dolucassi. I probably read about it but that was likely years ago and I don't remember what the answer might be. M-g, I think the picture is pretty good. Given the age of your car, I would also advise you to renew all of the rubber as in hoses, bushings and the main poly-v belt because rubber cracks, deteriorates and doesn't last forever. I would further advise that you change all of the fluids, oil, coolant, transmission, power steering, and differential. Be sure to only use MB coolant for the cooling system. Non-MB coolants can damage the plastic interior of your car's radiator. Radiators are now NLA so preservation is a must. There is a company in Germany, Kienle that can now refurbish vintage MB radiators if you need to do that. Don't hesitate to ask if you have any more questions. I'm looking forward to following your progress. This is a rare version of 190 so its restoration is important.

Yes its quite a cool and rare car so will be fun to put it together again 😁
Amg changed crank and also the bore, its 90mm in bore, pistons is different also
Head is ported/polished, different camshaft
So there are some major differences🙂
I will check with Mercedes if its possible to get headgasket and some other parts I need.
I hope so, otherwise it will be hard to put it together again
Will update once I have the car in the garage and start working on it.
Currently waiting to sell my z3m so there is some more space in the garage for this project 😁

Will update with more pictures once its home in the garage 😁
Yes I will change out everything that you listed, will check over everything so its in good condition.
The car is in quite good condition paintwise,just some cleaning and polishing and paint the left front fender.
Interior is quite nice also,drivers seat have some wear on the bolster that needs to be fixed.
Not sure if its possible to get new fabric like the original
but ill look into it
BTW, it is entirely possible that AMG did not change the bore of the M103 3.0 liter engine but just change the pistons to a lesser dome an increased the stroke to keep the compression but increase the displacement from 3.0 --> 3.2. If so, a standard 3.0 liter head gasket is the proper part. But you have to measure the bore to make sure.

Ok but I think all amg 3,2 engines were bored out to 90mm from the information I have found, but I could be wrong.
Previous owner said he measured the block and it was 90mm.
I will try to see what my local Mercedes dealer can help me with, hopefully the parts are still available 😁

That certainly will require a special gasket. In case you strike out, there are always shops that make custom head gaskets. That would be your last resort.

I'm inclined to think that the 3.2 liter engine was likely bored out but I might be wrong. I think your best bet is to try to work with the MB Classic Center rather than the MB dealerships. Some MB dealerships do have older MB model specialists and some don't. As far as parts, the MB Classic Center will be a better bet.

Yes I sent an email to classiccenter but they couldnt sell me parts and had to go thru a Mercedes dealer.
So have sent a message to a contact I have at a local MB dealership and see if ge can help me out.
But yes normally the people working at all brand dealership havent got a clue of any old models/cars.
Just the ones over the latest 5years or so 😅
Probably got my z3m sold, being picked up by a guy from Holland by the 27th
After that I will start working on the amg when I bring it home to the garage.
😉

That doesn't make any sense. I don't know where you're located but the MB Classic Center sells parts around the world and you don't have to go through an MB dealer to get parts from the MB Classic Center. The MB Classic Center actually has now put their parts catalog online. I forget what that address is but it should be easy to do a search and find it.
