More power from a 2014 2.0n/a

[Mrmcnulty]

Hello all I have a 2014 impreza limited 2.0n/a. I want to keep it naturally aspirated with a cold air intake. So far I've gutted the back seat removed the carbon filter from the air box and added a k&n after market filter. Plugged the hose port on the intake for the crank breather and added a separate filter. Going to remap and remove the egr and delete the ac but is there any other easy or bolt ons to gain easy hp? Also can I swap my 5 spd Manuel Trans for the 5 spd or 6 from a wrx or sti of the same year?
