Is that also available with a twin scroll housing? I'm not concerned with headroom for more power down the road, I'm looking for the widest powerband available.

The 5130 easily did 300 @ 8-9 psi and 350whp around the 12 psi level. I don't have any experience with a twin scroll 28rs based turbo on the fa20 platform but housings are available (.82 ar t3 divided). You could do it with either the PTE 4828, Garrett GTX2863 or GTX2867. I'd expect 400-500rpm faster spool with a slight loss of top end compared to the open scroll counterparts.
