dont know about 3 series...

but the crankshaft denotes the stroke...but anyways...
Ok the 528e uses the same crank as the 524td
and the 325i uses a short stroke and the same bore basically as the 528e...
but...what about the 325e?
people say the 325e stroke is different fromt he 325i stroke...
can someone confirm this?

-Yes, the 325/325e has the same crank and bore (entire engine, really) as the 528e, and the same bore as any US-market m20.

but what about the 325i 87-91...shorter stroke correct?

[nando]

the 325e/528e/324td/524td all use an 81mm stroke

the 325i uses a 75mm stroke

both have an 84mm bore.
