How upgradable is the APS ST? I know how Turbonetics is doing there thing on upgrading with the 1.5kit and 2.0kit, but is APS doing anything to upgrade? How upgradable is the single turbo that comes with the APS ST kit? Is the location a huge issue in this? Sorry for the long question, but the price is damn good for this kit not to ask...lol

 

not, no, not, yes. in that order.

 

upgradable? See sig.
