(E34) Which engine is best for turbo set-up?

[clevertd]

VaNOS turns on/off at different RPM dependent on load and temperature. For peak numbers? Sure, I could see the NV route, but there is more power under the curve and better driveability when VaNOS is used. There are many people out there that tune VaNOS and are easily contacted. There is NO reason to half ass a turbo system, if you do, you've got bigger problems.

People half ass them all the time to save money(just look on ebay)! I'm not saying half ass the system. I'm saying that most people will not consider that vanos will effect the turbo. A non-Vanos engine will be easier to tune w/ cams and easier to produce a more predictable boost due to the consistency of the power curve. Unless you tune the Vanos (which I bet more then 50% of people who turbo there BMW do NOT) then I think it is pointless to get a vanos motor. I've seen m50 non vanos engines w/ low boost produce over 400hp

Good thread!
In the thread both my and your points are proven!
Vanos=good for street
Non-Vanos=better for track
