I'm of the opinion the Edelbrock manifold is too peaky-oriented for street use. You only want a plenum that's so big and runners that are so short. It's mainly useful for very high power applications. Otherwise stick with stock or use a skunk2.

If you're getting a turbo, worry about the turbo first and foremost. Get it running well and once you hit the wall with horsepower through tuning, go ahead and start adding things that will raise the output.
