97VtecIN

Hey all, I am finally getting around to actually installing the Garret T3 turbo to my 97' Civic EX. I have the turbo and intercooler ready. It has an internal wastegate so for the exhaust manifold if it has a place for an external wastegate is it usable? Or can anyone tell me a relatively inexpensive manifold that I could use. Also I have some Venom injectors and Walbro fuel pump, do I need to replace my fuel rail? if so will one off of a b18 fit? Thats about it for now, if anyone has any tips please let me know... Thanks
