NA head is slightly different but can still be used. Will need billet oil pump gears put in, I'd change the intake manifold as the na one has the butterflies in it but no biggy there. You'll need a Walbro 460 intank pump, adjustable fuel pressure regulator, 1000cc injectors should be enough. You'll need some way to control boost or swap out the wiring and ecu for a turbo model one. ZF not sure about, I've still got my na one on mine and it's up to 190,000kms with 330rwkw and it's fine. Would nearly be cheaper getting an FG f6 or 06/06 on XR6 turbo motor and doing valve springs, cheaper and it'll handle the power. Sometimes wish I had done that...
