Your gonna need a full set of gaskets for your turbo. New bolts/studs/nuts to attach it to the manifold and down pipe, it's advised you do an oil and filter change too. You're also gonna need a bit of coolant. Speak to the r-tech guys about what fpr they reckon you'll need. Your fuel pump may require upgrading also. It may be worth getting either a high flow exhaust manifold or getting your oem one ported to help keep your egt's low and increase flow.
