Ok i want to be able to stomp some serious ass at the strip and on the street but still be able to drive the car daily. What is the most powerful turbo i should put on there... i was told a stage T3/T4 was the best way to go?

a ball bearing T3/T4 can produce all the power you could want. unless you are building a strip only drag car.

1997 Silver RS
Wiseco 8.8:1 Pistons(back to low compression!)
Eagle Rods
T3/T4 Turbo
Custom FMIC
Greddy Exhaust
440's
Most current 1/8th mile time: 8.3@90mph 2.015 60'(Nitto Drag radials, i suck)

T3/T4 isn't the MOST POWERFUL you can use, but it's a great turbo for what you're wanting to do with the car (street/strip). Actually, Star uses this turbo in there kits. HRC uses a S16G, upgradable to a larger S20G. Or you could just use a big ass T4! }(

I believe a T3/T4 flows more than a 20g... could be totally wrong though.

either ore you will have to rebuild your internals to run more than 10psi daily

What kinds of things would i have to do to make it handle that kind of power??

Primarily pistons & rods. I think the majority is running JE pistons/rings and Eagle Rods.

and your gonna need to get bigger injectors and an sfmu
