N/A Build?

So recently, I got a raise at work, as well as more hours. I'm getting a little tired of a stock ej253 with bolt ons. I'm looking to have some fun, while still staying N/A. What are some recommendations for internals, as well as some suspension upgrades, as well as maybe beefier shift linkages for the auto 4 speed to handle more power?

I have a 2005 2.5 RS (auto, shut up dont make fun of me lol) catback, resonator delete, UEL headers, injen intake, and perrin LCP. Sitting on rokkor coils.:monkey::monkey:
