Help with Identifying M20 Block?

Identify M20 block?

I completed the M30 swap into my euro e30. I initially wanted to sell this M20 motor but since I have it, I mind as well look for something to put it in. The previous owner installed this engine in the car with serial number on the block: 325 ETAUS 0195A 06 8.
I can’t seem to find any information on this block. For sure the head has the #200 at the end. I am thinking it’s from an E21 or an E28 but I’m not certain. Any help will be appreciated.

I'm not positive, but I think that is an engine from an E30 325e or an E28 325e/328e. It won't be from a production E21.
