PS questions + vacuum? Rb25det

[mattleegee]

rb25det s1Stock PS resevoir has that little sensor thing and a harness plug in, i was told i didnt need it so can i take out that whole assembly and trash it? It just has that one nut holding it onThen out of turbo and from PCV system there is a airline that needs to go somewhere, can anyone give me some help?I thought about taking the sensor out and just looping it from where it comes from and just have a little bypass there instead

Here are some pictures, i have a hard time explaining thingsThe assmbly and that airline? where does that go?The assembly that comes off the PS resevoir mountingA view of the whole thing and where it goes

Thank you much

I just pulled the sensor off and by passed it! You will be fine!

that 7/32" outlet doesnt need to go to anything or you just cap off that hole line?

yea thats the factory boost solenoid. You may bypass it by just running the vacuum from your wastegate to a boost source (any port before the throttle body plate). If you have a boost controller you'll T into that line and according to your boost controller diagram.

As for the PS sensor, are you referring to the factory sensor located on the pressure line of the original KA setup? If so you'll be able to get rid of it. As its purpose is to bump idle when the steering wheel is full lock and pressure is increased in the PS system.

most people delete the ps sensor. just might need to rev the car with your foot if you're doing a lot of maneuvers in a parking lot to keep from stalling.

THe PS sensor from the KA is just hanging out, i got the custom PS line with no connection so i already figured on dumping thatYou lost me in that first paragraph, take a vacuum where the boost sensor goes and run it to that 7/32" that its my picture? That is what im trying to get at, to see where it goes

BTW RICKY you find that hose yet? haha

Good to know, im just trying to figure out if it needs to go anywhere now or just loop and cap off that whole area

I did, i'll shot you an email.

Anyone?I am really curious what to do with this line, it has to go somewhere, just spent 40mins digging into the FSM again and no goI know where the boost sensor outlet is on the intake manifold, it cant go in there can it?

Search for "boost solenoid". I posted pics in a thread a while back.

[mattleegee]

Thank you Darius, but no luck, i did spend over an hour getting confused though by different statements

[mattleegee]

So what i have come up with so far

Remove solenoidRun WG line to intake manifold boost sensorCap off PCV/Intake line that used to run into solenoid

Doesnt seem right but i will take anything other then leaving all these hoses danglin around in the engine bay
