What is a good street engine displacement for a motor with a turbo for a street/daily driver? I was told that it is better to go to a smaller displ. with a turbo set up than it was to go with a bigger displ. Is this true? I was told this because, with a turbo, it puts out torque like it had a bigger displacement and that with more cubes it would just be wasted power because of the added torque. Now I know some setups would just create the "wow" factor, but I've seen pretty decent numbers from stock 302s with a single or twin setup. So if any of you with different size motors with either single or twin turbos that your car is mainly street driven chime in.
