the boost on the turbo and how high it boost depends on the turbo and if u have it set to boost high via a boost controller. um if ur planning ot upgrade ur turbo either have ur head retorqued down, or what is more highly recommeded; get a metal head gasket and machine the heads flat. dont get anything ridiculously big if its the only upgrade u have so far. if ur tryin to go big make sure to upgrade ur exhaust. and u probly want to get a new intercooler
