depending on the exhaust flange, you may need a td04 downpipe. the wepr manifold will foul on the standard rad, so they sell half sized ones, or you can use a different brand smaller rad. you will need, td04 manifold td04 turbo unit td04 downpipe obviously gasket set actuator if its not allready on the unit fuel pump fuel pressure reg larger injectors oil lines water lines fmic!! relocation pipe for air filter as well as rolling road time, and also an ecu (either chip, piggy back or standalone monster) im sure I've probably missed soething off the list, but that was quickly off top of my head bro to get the most out of a td04 you will need forged pistons and rods, unless you plan on never boosting it up ;) which would be slightly shite ;)
