I was looking at the vanos and double vanos arrangement on the later BMW 6 cylinder engines on www.realoem.com the other day when it suddenly occured to me that I have never read anything about variable valve timing on the V8s, 3 or 4 litre.

Do the V8s have variable valve timing ? Also, if not, why not ?

Sorry if this is a really stupid question !

id just go for a regular m62 so you could use the stock v8 harness and not need to deal with the vanos, if you want something spunkyer get a 4.6 from the bad ass x5/automatic z8, 340 something hp alpina motor

Choices galore. Maybe in a few years these motors will be real good value... quite a few are being sold- as opposed to e28/34 M5s and Schnitzers that were always as rare as RHS...

I would find an S50B32 engine from a euro m3 and stick a turbo on it.

500-1000HP depending on boost and mods, the iron block can handle a LOT of boost

Going by the troubles they had with earlier vanos units, I'm glad we don't gott 'em.:p
How expensive would it be 2 repair quad vanos (shudder!)

We only have sport mode, which changes the rev limits etc - goes from cruiser to beast real quick :D

alloy blocks cant stand the high RPMs

the diff between the euro and us S50 engines was the dual VANOS and individual throttle bodies which allowed the euro model to get a crap load more power and sound cooler.
