heh - I was like what on earth are you guys talking about - it never occured to me you guys don't see euro motors.
Dude - that is either a 320 or 323 motor m20b20 or m20b23
Not a 3 ltr.
I can tell because -
a) It is L-Jettronic fuel injection - most euro 325s are Motronic (I won't say all - i've just never seen a L-Jet 325)
b) etas don't look like that - and they are all motronic
c) It has the early euro rocker cover BMW roundel.
The tubing coming off the intake manifold goes to - 1: The distributor for vacuum and mechanical timing advance and retard. 2: The brake booster. 3: A little thingee that forces the throttle on when it is not under vacuum (hard to explain).
Pic attached - my euro m20b20 (from 1984)
