This question can't be answered so simply...that really depends on you, the set-up you plan to run, and in the end how much power you plan to make. For most applications a cast manifold is fine, in fact I'd say 80% of the people who turbo their car for street use are fine with a cast manifold.

My point is this, the manifold is not the "achilles heel" in a turbo set-up and any manifold whether a high dollar tubular or cast will get the job done, you will only notice the difference when you really start turning up the power.

There are many factors to consider. But to simply put, given the same boost and tuning on the same engine, a tubular (tru equal lenght) will most likely produce more power. I think Boosted-Hybrid from H-T has a video of a dyno comparison between a log style and their Full-Race (ramhorn) style manifold. It yielded more than 50 whp at the wheels.
