Stupid V8 engine question.

[Zeuk in Oz]

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 !

V8 dont have it, dont know why.

[tnt525i]

i guess they dont have it cause they got enough torque as it is ,,, just my guess

[winfred]

they didn't get vanos till 00-01, that motor then got replaced with the valvetronic motor in the new pig **** ugly cars

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...

Zeuk, if it makes you feel any better i have always believed there are no stupid questions just stupid answers!

[ThoreauHD]

Yea, what he said.. Uh,.. Wait a minute...

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

[liquidtiger720]

You my friend, are missing a great thing...this vanos. VTEC YO!

[Paul in NZ]

i thought the euro m3 were aloy,only the US got the iron blocks?Is that a stupid Q?

[BillionPa]

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.
