Hi, thanks for having me here, big hello to all you guys.
ok, I have a mk3 ghia x 2.5, really love the tub, want a little more performance if possible, ok I've read all about dropping the inlets and throttle body from the ST 200 onto mine, I have already seen a post here, regarding this, on a guys zetec s,
I have both upper and lower manifolds, throttle body, and bellows, and fuel rail, green injectors, and thankfully the throttle cable, I've read here, I wont need the lower manifold, as I already have it fitted, due to being the same.
ok so please correct me if I'm wrong, the upper manifold, throttle body and bellows, will bolt right on,without issue, they say the cable is different, how exactly, I have one , but just curious as to how its different, or the way it works, I'm unsure..plus the choke cable, is this the same as original
the next question I have is do I retain my original injectors, or fit the green ones, will fitting the greens cause overfueling, or running issues, and lastly will there be any issues regarding the maf.
thanks in advance guys
