I've got an 1987 2.0L Carbureted 190 that's running a little slow for my liking. Now getting a 2.0L or 2.3L 190E would be the ideal option, but half decent models are running over $20k here in Indonesia and most circulating in the market are automatics (I gotta have a manual 190).
Initially, I wanted to put an M103 or an M104 in my 190 but seeing that i'm working with a inline-4 2.0L base model, drastic changes might be needed to fit an inline-6 (please correct me if I'm wrong) and i'm also worried putting a 2.8L/3.0L in my 190 would make it nose heavy.
So I came down to two options: 1. Buy a W124 230E and rip out the 2.3L M102, put it in my 190 and turbocharging it. or 2. Buy a W210 E230 and rip out the 2.3L M111, put it in my 190 and turbocharging it.
the reason I'm going with the Na M111 over the Kompressor model is because i've read and heard that superchargers are space heaters (again, please correct me if i'm wrong). The 190 is one of my daily drivers and traffic here in Jakarta is just abysmal, don't wanna risk the car overheating. So which option do you think would yield the best result?

That engine looks awfully small. What is the displacement? I think we need to know that before we can give recommendations.
All I know is that changing from a carbureted engine to a CIS fuel injection will not add very many HP's for the same displacement.
No matter what this is a big job, and if you are going to tackle it you would want the most out of this project. An M102 2.3L or even an M103 2.6L is probably not worth the effort.
M104 HFM (E320) is where it would start making sense at least mechanically it should be a bolt on. Electrically, a lot of work. Same with the M111, but the adder there is more mechanical work on top of the electrical fuel management system.
You are probably better off finding a cheap car with a good body and a good M103-2..6 liter engine but trashed interior and start transplanting all but the engine and the chassis to the newly acquired car. I think that is a lot less work and less messy. A manual tran M103-2.6 has satisfactory power but not good enough for what you will be attempting.
Very nice car. I would go for the M111 kompressor but with a turbo to gain some flexibility on component placement. It will also be easier to get the high pressure fuel system working with a stand alone fuel injection setup even with some boost.

It's still the M102 and he/she could just swap over the intake/carb setup and keep the same fuel system. Not much to gain though with the small extra displacement.

Mine is a 2.0L M102.
Would going for a 3.2L inline 6 require me to do major modifications to the bay or firewall? I've read somewhere that with M104's you need a 190E 2.6 as a base due to the different location of the steering box compared to M102 cars. Moreover, Would going with a big engine kinda throw the car off balance?
As for the acquisition of a new car, It's highly unlikely for me right now as I just can't get behind the economics of it. 190Es are very rare here in Indonesia, and the ones that are on the market are in too good of a condition to take apart. Kinda hard justifying a $20k (minimum) purchase when I know an engine swap is gonna cost way less here (low labor cost).

Thanks for your response, right now I am leaning more towards the M111. But I've just thought of something, hypothetically speaking, do you know if it would be possible to do a carb to EFI conversion and then turbocharging my current engine?

I believe an EFI was never made for your engine so it will be a custom job. Yes if you can do that then turbocharging would be an option but again all custom work.
How many miles on the 2.0L engine? Is it worthy of all this custom work? I still believe a 3.0L from a 300E might be the most straight path to your success. Been done many times. You would go from 100+HP or so to 170+HP. That is a big jump.
At least you do not have to worry about the mechanicals other than changing out the radiator area and crossbar.
I don't think a 190 will have the electronics needed to run a M111 engine so that will mean more customization. I don't think it's worth your time or money to do such a swap. You currently have a very nice 190 that a 190 enthusiast would love to own. I think you should sell the 190 and buy something with the bigger engine already in the car. I think that would be the most cost effective way for you to achieve your goal of more power. The original 190s are not sports cars. The 16v, the EVO I and EVO IIs areconsidered the "sports cars" in the 190 universe.
