The turbo manifold off the 1.8 4G62 will bolt straight up to the 4G63 SOHC head (I had one lying around and wanted to tempt fate but decided messing with the turbo was off the menu) The same style of manifold was used on the 2.0 version of the Starquest/Conquest/Starion engine. The Cordia engines we had in Aust were...dubious at best. They ran lean, causing the manifolds to get stinkin' hot and crack (buying a second hand one can be perilous - due to the fail rate they are scarce). The good thing about the 4G63 SOHC head is the bung at the back end of the head is perfect for the oil supply line on a turbo.
