Stillen SC kit recommended upgrades?

I own a 2014 sport/touring and from what I have read on the forums, I plan to buy a SC kit, UpRev MAF GT, HKS Spark Plugs, 775cc injectors (in case I ever rebuild the motor and go for more power), FI Exhaust, Z1 clutch and flywheel combo, Z1Oil Cooler, and the Frozenboost Heat Exchanger. I can do all this over the next 6 months working as a contractor in Afghaniland.

Alright, now with the stock block I know that running 93 octane I should be wary of trying to go over 450whp. Would it still be cheaper if I upgraded my engine and pushed the Stillen harder with more boost instead of going the TT route to achieve the same power? Even with a TT at some point you will have to upgrade the engine. Hypothetically, with an impeller upgrade and pushing 12 psi with a built engine what would be some results that you think I could achieve? Would it even get close to competing with any twin turbo builds out there?

Also, I know a lot of people have older Stillen kits, but for those who have purchased kits this year; should I still replace the BOV that comes with the kit?
