turbo i can take most cars on the road and thats a win for me lol And i don't really know about the VANOS system as i mentioned earlier But i would like to learn and you seem to know a lot about it. And i do agree HP gain at high RMP is sooooo useless because you cant use it. It's never there.

Vanos is a variable valve timing system, and BMWs are not a strait line car, if you want to light to light, just drop a 3.91 diff on and go nutz

AHHH above 4000RPM i see i see, thank you.

Soo i've herd, the good old 3.91 differentiation never fails lol So VANOS is a valve timing system hmmmm did NOT know that. But i'm pretty sure that 3.91 is a bank breaker noo??

The condition of the chassis being considered is what determines whether or not the build will be worth it. Turbo-charging a power-plant that has not been boosted from the factory (produced in large numbers) can be very expensive.

Yah so i've been told it can be expensive. And you pretty much answered my other question, the chassis has to be in good condition ehh i don't really think mine would be since i have a 94 e36 325i but you never know i haven't gotten my chassis checked ever.
