I would say SC because it won't really surge which is REALLY bad, however I understand that our engines are set up more for turbo than SC. They make good torque down low and kinda die off up high. So from my understanding the power we make low will get us up off the line into boost territory, where as SC's (again this is my potentially flawed understanding) should be used for vehicles whose engines make their power up high and struggle down low.
Again, that may be flawed or at least overly simplified.
I'd say if you're gonna do it, go turbo.
