you already have turbo so you will need
fuel pump, injectors, ecu/tune
boost control method... ebc or otherwise
z32 afm... maybe
clutch
spend money on handling/braking to make it managable (and more fun imo) to drive unless you want to drag (:thumbsdown)
mentioned above is probably more than two grand. the fact that you have chosen a large turbo means you'll require the extra fuel system items to make used of the turbo.
only tip is to do what you can yourself to assist the budget and yer keep an eye out for deals on the forums
