hey there ben....how long does the owner kept the car running?just want to know some background of the car....try n ask him back,what parts that have been changed......since u said the gearbox is hybrid,then better start gathering some money for future emergency...u'll never know what he has done to the engine......i hope ur not scared or panic....there are many zth member's here who can help u....or why dont u search around the force induction thread to get some more info for your self....currently what is your boost reading?surely the owner left a boost meter for u:D
hope all of us can figure out sumthing for your car..turbo need a lot of caring..try to treat her as your wife...ehhehe...but u know,once u play turbo a lot of money is going to spend if your
right foot is heavy..:D..cheers
