    Hiya guys just wondering befor i order a new turbo, was looking at getting a k04-001 hybrid for my seat leon cupra 180 allready at stage 1 and full exhaust system from turbo and induction kit ( soon to be a direnza fmic with custom pipework ) anyways was wondering if the k04-001 would be a direct replacement fit for the k03s setup or would there be any modification need in order to fit

    Any advice greatly appreciated

    Cheers guys

    direct replacement yes usually, but check what actuator psi is fitted to it.. i've seen them at 12psi which on your existing map will cause over boost

    As soon as the turbo goes on its having a stage 2 map done with fmic fitted so should have a problem with overboost. Would i need uprated injectors and possibly a 4 bar fuel pressure regulator to go with ?
