hi, ive been looking into getting an 06-07 wrx as my first car but one thing i'd really like to know before buying one is wether or not the aftermarket modifications will be swappable to an sti of the same year range. i would like to know that because after driving an automatic for about 2 or 3 years im probably gunna want to learn to drive manual so ill just upgrade to the sti.

i know the body of the wrx and sti are the same as long as they are both from the same year range but i plan on putting a lot of money into this thing: full titanium exhaust, intake, stage 2 turbo kit (and all the stuff that comes with it), CF hood + trunk, and some bigger (wider) wheels

so if anyone can tell me wether or not these parts (particulalry the turbo)would all be intercahngeable to an sti i'd really appreciate it.
