well there are a few good stock subaru flanged turbos that are good, but most of them are more expensive when compared to a t3 flanged counter part.
although im not sure what clearance issues you may have some good size upgrades would be
forced performance: Green, or Red
Blouch: Dom 3, Dom 4
Element Tuning: Gtxx
im pretty sure there are more out there. All of the listed turbos will produce 350whp
I would if not too expensive, switch over to the garret t3 style flang to get more options at better pricing.
