It all depends on what you want.

If you want a bit more lag, but a dyno sheet that says 300+hp. Ask MMS what to do. I'm 99% sure a STi sized turbo upgrade will hit this.

If you go in asking for 400hp (heck anything 320hp+) the wrx motor will require work.

Remember that a WRX motor is not a STi motor.
