New Turbo and mods questions

[choiceride99]

I just got an Evo III 16G turbo. I dont want any or little boost creep. I plan on porting exhaust manifold O2 housing and I also have an Apexi N1 3" downpipe, high flow cat and Apexi N1 3" catback exhaust. Will there be much if any boost creep? Any one with setup or similiar hit me up. Any help would be great turbo is not on car yet.

Hard to say...what kind of bov are you using? there are many things to think of b4 just asking hey i might have boost creep.....

If you want boost creep gone completely cut the divider between the flapper and exh. wheel and port the o2 housing as much as possible.

The BOV has nothing to do with boost creep. It stops compressor surge in between shifts.

How much boost are you planning on running? I had a big 16g with boost set to 12 psi and no fuel mods, and it would creep up to about 19 psi. So I just didn't get on it until It was safe. After I got my fuel mods and turned up the boost to 18 it would still creep to 19. After porting I just wanted to see how low of boost I could run and I got it down to 15 pounds. So just port out as much as you can and you should be safe. Or you could just upgrade your fuel system and run 20 pounds, and not have to worry about creep.
