step one...buy thick header flanges lots of pipe and a welder/ If you cant wled just tack the parts good how you want them then take them to a fab shop to be welded up. look into master power turbos( brazilian garret knock offs) they are way cheaper than a comparable garret and quality is just as good. All i ghave to say is research research research over and over and collect all the parts you need before you begin.
