question about upgrade
 

still noob with rotary, just got a question, what else do I need to upgrade when I am getting a bigger turbo and more boost??? apex seal? gasket?

The stock fuel system has at most maybe 10% headroom.
The stock turbo and intercooler have about 25% headroom.
The stock AFM & ECU have about 25% headroom.
Two piece apex seals have 50-100% headroom, but they are exposed more the piston rings and will not tolerate detonation.

So - fuel & spark timing are the most critical when pushing up boost more than 10%.
Then turbo & IC to get above 30%.
Also, to go above 30% (10-11PSI) you are going to need a stand alone computer.
