Is VANOS Specific to any of the e36 engines in particular, or is it present throughout the whole range?

vanos did not exist until the 1994 model year. So if you have an m50 motor that is 1992 or 1993, it is non-vanos. As you can see in the picture I attached, this is how you can visually see if the engine is vanos or not. If this part isn't on an engine, it is not vanos.

it depends what your goal is for your car. if you plan on staying NA (naturally aspirated) then definately go for a vanos. If you plan on putting a big turbo or sc, it is much more difficult to tune a vanos car (but not by any means impossible).

Vanos is variable cam timing. If you look at the top of the red circle in that pic, there is a big solendoid there, and a plug wire on the end behind the head, which you can't see in that pic.
On that engine, it's just the intake cam that is changed, but on the new engines, both cams are variable.

Also David, the 4cyl cars dont have it, so until you upgrade to an m3 (if thats still your plan), VANOS doesnt affect you.

the 93 or 94+ i6 have vanos, and some later e36s even have double vanos i think.

I stand corrected with vanos in 1993.

MAXI - the 1991 325i was a m20 motor. Those never had vanos. Unless he has transplanted another motor into it.
