    from my past experience tuning turbo cars if you get hold of a cosworth T34 hybrid turbo and theres plenty about and they also come with a internal wastegate set to 11psi which is enough for the 325 and get a manifold and exhaust made up and get some bigger injectors with a walbro pump with a FPR and run a fmic thats the basics covered.

    You will then nee a oil feed pipe and also a oil return and with T34 turbos there also water cooled aswel so you will need to sort that out which is simple really just take a feed from the coolent pipe going to the throttle.

    You will need a good mapping company to setup the fueling and boost if you want to run a controller.

    The standard head gasket will do just fine aslong as the fueling is all setup correctly.

    This is a very long list its not as simple as bolt a turbo on and go weeeeeeeeeee tssssh bang


    hope this helps

    If you're not restricted displacement wise (e.g. keeping it 2.5L for competition reasons), I'd for the M3 engine. Best bang for buck, imo.
    There are only two products required to make the universe work properly: Duct tape and WD40. 


    If it moves (and it shouldn't): duct tape. 
If it doesn’t move (and it should): WD40.

    Everything else is just stuff.

    The turbo looks fine apart from there is no real description of the turbo at all and have you found a source for all the other components needed?

    just a rough guide
