For starters youll need some oem components, if you got the cash I would build up the internals for boost that way you can always KA-T it. Definatly get a new OEM timing chain kit and OEM water pump as the generic store bought stuff is pretty cheap and breaks often and your water pump and timing chain are really important. Look into getting a decent head gasket, again to withstand power. For this kind of information I recommend NICO and KA-T.org. Good luck! I might be rebuilding my daily drivers SOHC in the near future.
