turbo motor build

Hey guys,

Know this has prolly been asked a hundred times, but y'all know I'm kinda slow.
If you're building a second gen turbo, would you start with a series 4, or a series 5 with the higher compression ratio and lighter rotors. Is it dependent on your HP target, or is the lower compression motor more desireable for turbochargeing?
I ask this with the assumption of not using a series 4 turbo/manifold combo with either.

Thanx, Gregg

series V. The compression of the rotors makes more power and it fine with big boost.
Personally, I'd start with a 3rd gen engine.... or a 20B.
