Port and polish is a waste of time on any turbo that flows less then 60lbs/min. For you, I would get either a set of cams and/or a sheet metal intake manifold. You will see great improvements performance mods from either of those mods. You don't need springs, retainers or valves unless something is wrong with yours or you plan on shifting past 8k.

Cool, thanks Jerrome.
