If I decide to, in the future, get a VF34 turbo along with either the Process West TMIC or an STI TMIC, what other supporting mods would be smart to make sure my car is reliable but still quick. It is my daily, so the car needs to be reliable otherwise I won't go ahead with any mods what so ever, and I do not plan to race.

Current mods:
3" tbe
500hp fuel pump
ecutek tune, type 1.5

and approximately how much power would the vf34 and a new TMIC give me on top of what I already have?

EDIT: sorry forgot to say what car i have haha, it is an MY00 WRX club spec evo 4
