Can't find where an m20 came in an 89' 325.

After about spending 8 total hrs going through [U]all[U] threads with the search of "M20". I see where there are owners with the setup of an 89 325i m20; i am find many web pages that don't list the m20 as being available for this year of e30 "325i".
Like BMW Used Long Block Engine M20 E28 528 528e SOHC parts:eBay Motors (item 370148366196 end time Jul-20-09 14:13:07 PDT).
I am probably going this route along with a chip and other minor tweaks.
This car was meant to be my daughters college car; but if i like it after it's running i may swap out my Taurus with her.

I apologize for the poor grammar, have been bugged eyed finishing up with reading of the posts for the last few hours.
In the middle of the page you will notice that the year ends in 87'; is this a type O or am i missing something?

The engine block in the ebay link is from a 528e. That means an ETA engine, so what would compare with an E30 325e.

"so what would compare with an E30 325e." did you mean " so that...
What does ETA stand for? i have seen it mentioned but have not found meaning?
Thanks witeshark,

The M20 ETA is a 2.7L lower revving, higher efficiency engine producing 127 hp @ 4250 and 169 to 177 ft·lbf @ 3250. The 2.5 (from the 325i and is) produces 168 hp @ 5800 and 164 ft·lbf @ 4300 (there can be slight variations).

thanks for the info. i assume there is a piston height difference and maybe a cam duration/lift difference, but wouldn't a 2.7 vs 2.5 mean larger displacement or a longer stroke?

thanks DRZ,
and... a good reason not to use this platform. But maybe worthwhile if my daughter will be driving her.
Thanks again...
