How much should I port to prevent boost creep

I'm about to install a b16g onto my car and was wondering how much I should port the turbo, o2 housing, and turbo manifold to prevent boost creep (2.5", 3"???).

you will not preent creep from porting the o2 housing, or manifold, but you will gain performance, get rid of the step in the manifold, upen up the runners a bit if you want to, make the o2 housing, as big as possible, the more you do there the better.
But as far as theh turbo goes, porting the exhaust housing will give you more performance, but if you want to get rid of creep, make it so that the wastegate arm can opena full 90* at least, and do whaterver you have to do to maek it do that.
from porting thee things properly, you gain gain HP, spool up, top end, and help prevent creep, make sure you have some nice carbine burrs, and a free weekend.
I did all this to a 2g manifold, a 14b, and a o2 housing, and got some major performance out of it, and got zero crep when just running a open 3in downpipe, with No cat
good luck

how much did you port the wastegate opening? what about porting the exhaust side and the inlet side of the turbo. any tips and tricks for doing this that you have learned. i'm about to rip out my 14b and spend a weekend porting that and my o2 housing. allready have the evo III manifold so that wont be a problem.

thanks
