vaccuum hookup

[okinawa drift]

im trying to get this s*** all squared away so bare with me

OK so my current set up is ISIS intake manifold, and i have no idea what kind of throttle body i have heres a pic



ANYWAYS, there are 2 vacuum metal tubes that come off the intake manifold right below the throttle body, and theres 1 metal vacuum tube that comes off the throttle body itself (not visible in picture)..

anyways is the metal vacuum tube that comes off the throttle body at constant pressure? is that where i hook my FPR up too?

i hooked up my FPR to that with a T to my boost gauge, and its reading 0 psi at idle, and when i rev it, it drops around -15 or something like that

the 2 metal vacuum tubes on my intake manifold, 1 runs to bov, and the other runs to actuator

let me know if this is the correct way!

hopefully that all made sense..

No, Please make sure you run your FPR to a KNOWN good vacuum source. The one you have it hooked up to now doesn't sound like a vacuum source since it's not pulling any INhg at idle.

Check to see if the port thats cmoing off your TB is BEFORE the throttle plate, on the intercooler piping side.If it is hook up your wastegate line to that.And hook up the boost gauge and FPR on to the manifold port

But don't drive the car the way it is now since you're probably not getting the right fuel pressure

got it all firgured out! thanks for the reply man, i had the FPR hooked up to pre-throttle body, so i just hooked it up to the manifold and now its pulling around 15-20in/hg at idle
