Yep, twin scroll would be the way ahead
OP, there is a reason you dont see many twin turbo'd 4 pots (or engines in that sense that use a smaller turbo then a bigger turbo), mainly the issues they had on the twin turbo legacy's was the take over period where you would get a bit of lag, plus what you gained in spool you wouldnt have lost that much with a single turbo anyway.
VW do a supercharger/turbo charger if you wanted to go that route but twin scroll would be the better all rounder (with avcs of course).
