Chevelle turbo sizing
Chevelle turbo sizing My brother has a 71 Chevelle with an LQ9 and L92 heads. It's equipped with a 4l60e and 3.55 gears. Compression is 10.4. He is considering a single turbo build with the hopes of a low boost, low rpm, torque rich characteristics. Is it even possible to find a turbo that spools up quickly, makes plenty of stump pulling torque and still gives you a 600hp motor at higher rpm? 
While a cam may fix the lack of torque, it won't give you torque and that high a hp correct?

Your going to have to undersize the turbine to get those characteristics. The new Turbonetics 7675 or a Precison 7675 would do it. On a budget the S400 is an option too and half the price.
The 4L60E wont last long if he drives it hard on 600rwhp.

Twins aren't an option. More piping, more parts to supply hp a single turbo can. Nova what a/r are we talking about for the S400. Personally I would rather he get a screw type supercharger but they are staggering in cost.
