VANOS engine fit a non-VANOS '91 525i?

[winfred]

that would likely suck, the vanos is a milder motor, it has less lumpy cams, it makes up for this with the 3-4k intake cam advance. the non vanos is a hotter motor. i doubt they are talking about leaving important equipment like a advance unit unhooked, if they are they suck more then i gave them credit for, i have a couple sets of hollander's and learned to not lean on them too much

OK, that sounds reasonable, if the cams are radically different. They only mention oil-pan/exhaust manifolds as being possibly different (between 325i and 525i '91-'95). I have seen some issues with Hollander, but usually they err on the safe side. This would be the first time I saw an error like this. Thanks.
