ive been a member on there for a while and youd be surprised how little those guys know about engines period.  I can think of about 2 or 3 people who might know, but i havent asked.  They all talk about upgrading to larger Mitsu turbos like 14T, 16T, 18/19T... only one guy has made a kit and it uses a small trim t3/t4.  So really when it comes down to it, im in uncharted waters... again.  
I was doing somemore thinking and i think the Super 60 MIGHT do the trick.  With ONLY an ECU upgrade, i can make a 40bhp/52lb-ft jump... that leaves about 70-80hp left to gain from exhaust work, a turbo swap and nearly double the boost pressure.   
I dunno... ill have plenty of time to figure it out.
