any turbo that is factory would best be described as conservative. they give a bit of power but retain good economy and reliability. we are not talking about factory fitting. we are talking about performance upgrades! where economy and reliability are sacrificed a little for that word that puts the sparkle in the eye! 'performance'. the turbo you mentioned would be lucky to wake you up and i think most people would find the return very disappointing for the money and effort they put in. the gtir turbo on my car makes 150hp on 12psi at the moment with potentual for 20psi of usable, drivable power around the corner. you are not gong to get near that with the mentined turbo.
