yeah im still thinking about my next step, but my plans were for an aftermarket exhaust manifold and plenum, aftermarket crank and pistons and new valve springs ect. after these mods i would feel more inclind to increse boost.
my gt30 is internally gated for now, i opted for that as i didnt have the extra 1000 at the time for the external, but that will have to be changed also.
i havent considered wmi as yet, ive got the .82 housing too, sounds the same as yours.
ive got pics on my phone of the turbo, hopefully get them onto the computer soon. its low mounted, but is obviously not stock, which makes me very paranoid.
