Stick with a twin scroll turbo setup. Far superior to outdated 16g. That's a ten year old turbo, if not older. Turbos have come a LONG way since the 16,18g turbos. Twin scroll is where it is at. 16g is a single scroll and slow spool. Max spool with the twin scroll stock is at 1750rpm. Only a twin scroll setup can reach that. Twin scroll means dual exhaust inlets.
