hey guys, i need a hand with the settings on my boost controller and possibly where i've placed my vacuum lines and such.

i have a turbo back 3/3.5" exhaust with a high flow cat, front mount intercooler and a pod incase you need to know.

sounds pretty dumb but i don't know how to set the boost,

i thought one setting was 7 psi and the other at 10 but my boost gauge went up near 15 psi and i'm aware you shouldn't go over 13 psi on a stock turbo

the boost controllers pressure signal is tee'd in at the fuel pressure regulator and the gauge at the back of the plenum at the stock boost controller/gauge i'm not sure how accurate that is.

have the boost controller solenoid hooked up to the wastegate properly, i presumed the line coming from the intake pipe infront of the turbo was good enough for my pressure line then it said the 3rd port you vant to atmosphere but i have it venting into the intake pipe going to my intercooler

i have searched and read through the manual and searched some more

sounds like you have the solenoid lines wrong. run a line from the nipple on the cooler piping (after turbo) to the com port of the solenoid. then run a line from NO to the wastegate actuator and leave the 3rd port open to atmosphere (you could plumb it in before the turbo but its not needed, just make sure its not blocked and doesnt see boost).

ohh ok, yeah that makes sense. Thanks mate =)

i'm also thinking of moving the boost gauges Tee peice into the vacum line for the blow off valve

No you dont want to do that. T it in to the line that provides your fuel pressure reg with a vacuum signal.

If your lines are setup as per the diagram it should work fine.

Start off setting up the eboost with a reset. Then go for a drive and make sure its not overboosting. With everything reset to defaults it should run the lowest possible boost. Then, and only then should you start playing with the settings.

    • Kinda glad I never got to this ..    https://www.facebook.com/groups/1483859159195077
    • @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.  
    • I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.  
    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
