You are so wrong, it's not even funny. The hot cams and dual valve springs allow for a lot quicker response, a lot more power/torque in the lower RPMs, and so on. The point of vanos in the first place is to adjust the intake cam to breathe more at higher RPMs when it is triggered. The non-vanos already does that, but throughout the RPMs, starting at idle. You may be able to achieve better gas milage with a vanos version because of the cams and vanos, but in no way will you be able to compete with the power provided through the setup on a non-vanos one. I forgot to mention that even the block has better components in it. The connecting rods are a lot beefier then most of the other M50 versions out there, which include the M50tu, M52, S50US, and S52US. The stock form of the motor is a great platform for FI already, just think of what some simple headgasket and ARP studs could do with it. Before you start talking, make sure you know what you are talking about and have the ability to back it up. Thanks.
