Almost done with my build and Im at a roadblock. With my build I got a crazy deal on an Xcessive intake manifold so I bought it just cause. And now I cant figure how to route A. The brake booster vac line and the FPR.
The manifold has ports for routing vac lines but my question is what about when the motor is under load and it goes from vacume to psi? Wouldn't you have this problem with the stock manifold too?
The reason I ask is because I have the booster and fpr already routed to the manifold and I took it out for a drive and no brakes and 0 power running crazy rich.
As of now its got 370cc's "Im not going for any crazy power" Im waiting on my RS. Enthlapy ecu so Ive just been messing with the SAFC 2 for now but even on that I had to turn the fuel down 50% just to get it to idle. As if I had so 550's in the car.
Long story short can anyone tell me where I should run these vac lines?
I know the majority of us are not doing some left foot braking so I should be able to figure that one out. But will it affect anything once the booster recieves psi?

Z31 turbos had a check valve in the middle of the brake booster line. $15 at Nissan. The fpr is fine. You need a GOOD tune. A safc is ok for fine tuning. But don't drive it until you get a proper tune.

My break booster leaks slightly under boost with out the check valve, So makes sure you have one. The FPR is fine to see boost.
