My sister went off to college and left me her 1993 BMW 325i.  Its in good
shape all around with just over 100,000 miles on it, but it has really bad
acceleration.  It goes 0-60 in 14+ seconds.  Any tips will help, thanks.

That's such poor acceleration that something big is wrong.  If the check
engine light on, the computer has gone into limp mode due to a bad
oxygen sensor.  Also, you should have the catalytic converter checked -
if it's failed/plugged it could cause this.

It's *slightly* possible that a failed VANOS actuator could cause
poor power, but it's usually not bad enough to take away 1/2 your
power/torque.

As the other responder has mentioned, if it seems like the auto
transmission is slipping, the transmission may need servicing
or replacing.

The problem is, you don't know what the problem is.  You'd be wise
to spend the $80-$100 for a mechanic with the diagnostic tools to figure
out what the problem is, then go from there.

An O2 sensor and catalytic converter are easy; auto trannies and
the VANOS actuators are jobs for specialists or very experienced
home mechanics, which it doesn't sound like you are.

One VERY simple check, how dirty is the air filter? I saw a 520i do the
same thing, the air filter was ancient and letting practically no air
past!

definitely go for service. specialized check-up of course. a 325 should
accelerate under 10secs without a doubt. my STOCK 320i e30, not e36, does it
around 9secs. but manual.
