Ok, removed emissions, bac, and oil injectors.

Where do these go?

Fuel injector-bleeds:
Fuel pressure regulator:
Pressure Sensor:

These should be the only six vac lines I need correct, everything else cap off? I assumed that all vac ports after the TB plates (did tb mod btw) would work. I'm having problems though.

Right now I have fuel injector bleeds capped off. Fuel pressure regulator goes to the nipple/port under the LIM, and the pressure sensor goes to a port after the TB plates on the TB.

Car won't run under 4k.

S5 N/A (and I can read text easier in this case than looking at the modified vac diagram for turbos)


Where do the ports go? Can they be connected to anything after the TB plates?

 

They all go back where they came from. You did take note as you were removing them didn't you?

Not all of the nipples positioned behind the TB are in fact fed from behind the throttles. Some have passages that lead to the front of them. Make you you use the right ones.

 

Ohh... kay? umm..well theres no vac rack anymore either?

 

That doesn't matter. If you didn't know where they went to before removal you should've traced them all the way back to their source before removal. The FPR for example connects to the manifold via a solenoid, so you follow the line from that solenoid to the manifold and connect the FPR to there. Same for anything else being reconnected. This seems so obvious, yet some many people don't do it and find themselses having exactly these problems.

Like I said, not all of the nipples are from after the throttles. The fuel injector bleeds need to be fed from before the throttle; the FPR and pressure sensor need to be fed from after the throttle. Where ever possible you should use the same nipple originally used, as that is where Mazda determined worked best.
