hey guys, ive tried looking for a picture on how to put back the stock vaccums back into the solenoid. anyone got a pic of it?..

for an r33 gtst series II if it makes a difference.. it would help heaps :)

ive tried looking on search but all the pictures have been deleted.

thanks again

Should be pretty basic if you have the original parts.

Put the T-piece back in where the other solenoid was if electronic controller.

Or if just the wastegate actuator holding boost, cut the rubber line between the intake nipple and wastgate actuator and put the T-pice in there.

The end of the T-piece needs to feed a line into the bottom nipple of the original solenoid.

The top of the solenoid should then feedback to a nipple just after the afm i think.

That's it!

Might have the top and bottom nipples mixed up though

(I think I've used the word 'nipple' too many times :) )

The solenoid acts like a bleed valve boost controller.

Bleeding off some air to fool the wastegate actuator to raise the boost.

A turbosmart bleed valve lets the air go staright out into the engine bay but the bled off air from the standard solenoid gets fed back into the intake pipe just after the AFM. Probably for meeting Jap/Aus emmission standards and all that crap. Just follow it down and you will see.

with mine, the workshop re-connected it so that the original t-piece pipe goes into the outlet(horizontal one) of the bleed valve(same as above) and the other connector which i assume is the intake(vertical one in line with the screw) is pluged to nothing. does this sound right? i dont see how it could work as from my understanding the air passes through the bottom of the bleed valve, gets controled by the bearing and spring and exits out the side into the actuator.

they said its set to 11psi. car makes 199.6kw first ever dyno tune in shoot out mode with adjustable exhaust cam pulley, r34 smic full exhaust, arc induction box and exedy flywheel. seems abit too high for me to believe. stock guage reads 7 or just below that. how can i tell if im running free boost? i think its time for me to get a boost guage..ha.

what do you guys think of my bleed valve setup?

      Should I use rust converter on this?

      Should I use rust converter on this?

      By PranK · Posted

      One of the first jobs with the E39 is making sure the tailgate stays up. In BMW fashion they made a little cavity under the roof to hide the dampers rather than putting them down the side like everybody else.  As you can see I have these little cavities that house the dampers. When I cleared one out and vacuumed as much crap as I could out of it I noticed a fair bit of rust. The cavity is bone dry, even after all that rain we had only a few days ago so I'm assuming that whatever allowed the moisture in is fixed but I'd like to treat the rust in there.  I was thinking of just blasting it full of rust converter but I didn't know if this would be beneficial considering I can't actually get in there to prep anything.  Maybe there's a better product?  Thanks guys

      Help Understand GTT Boost Setup

      By GTSBoy · Posted

      The stock boost solenoid is just a valve. Power it and it is open. Unpowered, it is closed. When it is closed, there is no boost bleed out through the solenoid back to the inlet. The wastegate sees all the boost pressure, thus you get the wastegate's spring pressure as your boost pressure. 5 psi. When it is open, it lets some boost escape. This causes the static (boost) pressure in the line to the wastegate to be lower than the pressure in the intercooler pipe. There is probably a small restrictor in the solenoid or one of its lines to limit the flow rate of the escaping air, which limits how far the static pressure can fall, which limits the extra boost. The boost has to climb above the original/wastegate setpoint until the wastegate sees 5 psi. You get 7 psi in the intercooler pipework. A manual boost controller is exactly the same setup, just without the ability to change it on-off. It's always set to whatever you set it to. There is a small leak from the boost controller. The more you screw the adjuster in, the more it leaks, the lower the pressure seen at the wastegate and the higher the boost will be. So, yes, your diagrams are correct.

      Help Understand GTT Boost Setup

      By DraftySquash · Posted

      Hi everyone, Apologies in advance if this feels like a topic covered multiple times. I'm only asking because some of the old topics I found are missing images now. I'm in the process of getting a manual boost controller (BC). Nothing fancy, just getting a manual one for now as I don't plan to go crazy with it and would not go over 10 PSI. My car is not jacked up on boost steroids to do crazy numbers. I want to understand the OEM setup of the boost solenoid and vacuum lines on the R34 GTT so I know what needs to be changed when I do install the BC. I sketched the current setup to the best I could see and it's on the diagram attached. If the boost controller 'Wastegate Arrow' goes from nipple 1 to 2. My understanding is that the red vacuum line's "F" connector-end should be connected to BC nipple #2? Nipple #1 is meant to have the "pressure source" so what vacuum line would that be? Is it the green vacuum line?  From what I have read here, the OEM boost solenoid is not used at this point. So that can come out and then I can just plug the nipple that usually connects to the blue vacuum line?  So would the final setup look something like this?   Thanks in advance. I don't want to already be knee-deep into pulling out vacuum lines before understanding this. I'm a noob when it comes to boost setups so trying to learn as I go.
