S4 NA -- going 6port turbo. I put on my TII manifolds, now the NA secondary rail wont bolt up to the TII manifold. on my NA, the fuel route is opposite of this diagram below.



my fuel comes in on the front (left on the diagram) side, and exits on the left side as well. I had two ideas.

1) could i get a TII secondary rail and flip it (so the fuel exits the front/left side) and rig the mounts ? and that way i dont have to reroute the fuel lines.

or

2) get both TII rails and re-route the fuel lines, but then since the fuel is coming in the opposite side, do i need to switch the injectors from front to back and vice versa?

 

the easiest thing to do is to get the TII fuel rails... as far as routing, the most important thing is to make sure that the FPR is the last in line. otherwise you will not get the proper fuel pressure to the injectors

as far as "riggin" the mounts, you will find that the holes for the injectors are in a different spot on the secondary rail(IIRC the NA's are farther apart)
