[justmeeematt]

Hey guys, its time i think for my zxtt to hav a full engine overhall. I want the turbos also done as well as new wiring harness and new pipes. I have $6000 and im not sure how to spend it in terms of what parts shld be aftermarket or nissan. Aswell as what shld be upgraded or what should be left standard. At the moment everything is stock. I would really appreciate any advise you may have! Thanks!
