I am wondering if anyone out there has put an old xr3 inlet manifold, The old ones that go to the left hand side with ford wrote on the top!,to an efi turbo head?? does a fez throttle body fit? Is it worth fitting it? does it give any flow/power increase?? Has anyone tried it? let me no as im intrigued to find one and fit one!!! Thank U!!!!!!!!!!!!!!!!!!!
