hey guys. just got my new k03. and im taking it monday to have installed. the guy that is installing it is a mechanic but not a audi mechanic and hes a personal friend of mine. so hes not even charging me to install. he says its not a hard job because its bolt on. but i wanna make sure that he does specific things. ive read to oil the bearings in the turbo. is this correct? and if so where are the berings? and what else should i tell him to do?
