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.

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?

      Lets say I wanted to buy this, specifically for this purpose. How do I actually perform the function. Can I still buy a Consult-1? Am I about to be burned by the fact my car is a 2000 model Series 2 R34 and thus will be some stupid other system? Do I just need this -> https://obd2australia.com.au/product/nissan-consult-14-pin-to-usb-ddl-diagnostic-interface-with-ftdi-ft232r-chip/ And with what software?

      That's probably OK. That's a face to face compression joint between two surfaces with the clamping load provided by those bolts. So.... it's unlikely that the bolts will end up feeling that load in shear, unless the clamping surfaces are not large enough, bolts not got enough tension on them, etc etc to prevent the two faces from moving wrt each other. Which... I would hope the designers have considered, seeing as it's probably one of the most important things the upright has to do apart from resist collapsing in its own right. But yes, it would definitely be worth asking them what their safety factor on that part of the design was. I tend to think that the casting, being a casting, is not necessarily the strongest bit of material in the world. It's about an inch square, and when you think about the loads that are being put into it, you have to wonder what safety factor the Nissan boys (and every other OEM engineer who has designed all the millions of other uprights that look essentially the same) used to account for defective casting, aging, severe impacts on the wheel, etc etc.

      Those bolts would be orders of magnitude stronger that cast aluminium though.  And its mainly clamping force, not shear they are dealing with?

      Except all that twisting force that is breaking a cast piece, appears to be going through 4 bolts in the picture Johnny posted of the BryPar one...

      R34 auto to manual conversion help

      By GTSBoy · Posted

      The smart approach is to use the gearbox loom from the manual car. Makes it a lot easier - just plugs into the switches on the box and plugs into the main loom up near the fusebox. Then you only need to deal with bypassing the inhibit switch. The other approach requires you to use the wiring diagram to identify those wires by colour and location, perhaps even indulging in a little multimeter action to trace them end to end to make sure, and then.... you will have the answers you need. The R34 wiring diagram is available on-line (no, I do not have a link to it myself - I would have to do a search if I wasn't able to go to the copy I have at home).
