If you are after the safest F.I setup, go with a centrifugal S/C like jackson racing's kit. The way they build boost with RPM is less stressful on the bottom end, the rods specifically which are known to snap when you up the torque.
Turbo kits and twin screw setups will make a lot more torque down low which will put more strain on those components. The trade off is that they feel faster through the entire rev range, as apposed to centrifugal blowers retaining the factory powerband, just more of it.
