turbo upgrade

hello everyone, i have a 07 2.5 WRX with ecutek, K&N tayphoon, catless downpipe, center pipe and turbo back, and a fuel pump. Im running around 270HP and i have around 18.5psi boost. I want to upgrade my turbo now, im aiming for around 320HP. the question is, if i upgrade my turbo and stay with around 18.5psiwill i have to change my pistons and put reinforced ones?? or can i keep my car like it is and just install a bigger turbo?? will i have to worry everytime i drive my car that my engine might break? thx

If your pushing 320 to the wheels on a 2.5L you'll be fine. Just make sure your injectors will cover you depending on how big of a turbo you get.

I do believe the stock internals should be ok at 320 hp. From what I've read, i'd be more worried about the transmission going than the stock internals at that stage.

you will also need a protune to get the full effects of an upgraded turbo
