300zx-tt Reasonable power for street
 

Hey I'm new here and looking for some insight. I just picked up a 91 z32 tt with a blown motor and my plan is to rebuild it and turn in into a fun weekend car. Since it's blown I'm just going to rebuild with forged internals/ head work and ill upgrade suspension/brakes/wheels/tires. My question is what is a reasonable amount of power for this car as a street car. I was thinking around 600whp but I figure that will be impractical and a little overkill for street. Is 500whp practical for street or still a bit much? Since I'm building it I wanna get as much power as I can out of it while still being a comfortable car to drive.
