Eric - there (to the very best of my knowledge) is not and never
has been a 3.5l six-cylinder 24 valve engine. There is a 24 valve
6 cylinder - started in '91 or 92 (called the M50). Puts out about
the same HP and torque as the older (pre-1990) 3.5l engines. You
can spot these cars (I'm looking at several) by the 525i emblem
on the back - the earlier 12 valve engine the letters are straight
up/down. On the M50 cars - the letters are slanted (little piece
of trivia a friend passed on).
All the ones I've looked at are '92 and newer. Have heard no
reports of real engine problems with this engine, I think it is
probably a winner. Same power and lower maintanence as the older
design 3.5l. (And it does have chain drive cams - something I
insist on - no belt to replace periodically).
'Course a 24v 3.5 liter would be a very nice thing, but might
cut into the V8 range a bit.. (God meant for me to have 6 cylinder
in-line cars.. the engines are just SO sweet!).
Best,
