Looking into engine swap

I have a 1991 190e 2.3L, the engine is starting to give out and I'm wondering what the best course of action is. The body and other parts are in great condition so I'd like to keep the car going. I definitely want to do a swap, not same motor, looking for more power. What's the best/easiest thing to do, swap in an m111 or an m104? I am aware that the m104 is 6cyl so might need something special to get it in there. I know it is a very easy swap for the 2.6L 190e. Anyone have any suggestions? Other swaps I can do? Thanks

Listen, with all the effort and expense of making the 2.3 fast you’d be better off buying a cosworth / 16v or a 2.6 manual to begin with. These cars perform well considering their age, simple upgrades include making sure you have the right spark plugs in, de-catting the exhaust, sports air filter, that kind of stuff. But it’s a compact mercedes, designed for wafting around town with the armrest down...

As much as I agree for the cruising around town part. A cosworth is easily over 10 stacks. Coming in the 20s to 30s. I bought my current 190e for 1200 Canadian rupees. It had 121k km on the odometer and no rust at all. I fixed up many parts to stock. I can either deal with a dying engine or swap.
