Does this look like its setup right?

the left hose is connected just after the compressor,

the Tee feeds 2lines to the tial 44mm which has both hoses on the bottom row of ports, should there be one on the top and one on bottom instead?

the hole with nothing in it is labelled "NO", and when doing a pressure test for vacumn leaks it was leaking massively, is that normal ?post-70965-0-11252900-1372838132_thumb.jpg

ok thanks for that link, ive studied that and its clear that its hooked up wrong, but im still trying to understand why when I hooked up compressed air to the system that the "NO" was leaking out air, this was with 0.3Bar with combined 14psi springs in the gate..

could the solenoid be stuck open or is definitely due to being plumbed up wrong?

I could be wrong, but have you tried testing it with reds "on" this would power up the AVCR and solenoid. My understanding is that the solenoid pulses lots of times to control boost. If you put some air into it while off, it may have stopped in an open position. I could be entirely wrong though! haha

thanks for the input guys, all good now, tuner setup it up for me today same as above link, the solenoid is actually meant to vent air off if running spring pressure and when adding more boost it uses that air to push on the spring to adjust boost higher than spring pressure. if that makes sense. :whistling:

Mate could you possibly update or pm me with how you have the avcr set up with the gate or a sketch so I can make sure mine is done properly when going back on Dyno in a few weeks?

Had to cut last Dyno short as I didn't have it hooked up right damn it.lol

I have a gtt as well

no probs, see in the pic on my first post

the hose on the left goes to the top row of ports on the tial

the 2 hoses on the right of the solenoid - one is plumbed just after the turbo compressor, cold side

the other plumbs into the bottom row of ports

all other ports are plugged, the solenoid works by bleeding off air until you want more boost than the spring pressure , in that situation it forces are to the top port to help the spring keep the gate closed.

which is what the diagram in the manual in the above link shows ...

hope that helps

      Single Turbo Conversion On R32 GTR.

      By StevenJames32 · Posted

      Hi everyone, I'm about to complete my first single turbo conversion on my R32 GTR and I thought I would post the step by steps that I will be following. I will list the parts I have / the parts I will be buying. I will be redoing this guide after I have completed the conversion. Parts list: - 3576 turbo 0.82 v-band (coolant and oil)  - v-band top mount turbo manifold - 50mm wastegate - manifold copper gasket - titanium manifold stud kit - turbosmart 3 port boost solenoid - link can lambda kit (wideband) - link ECU - radium 12AN push in valve cover fittings (pair) - hi octane catch can - 3.5inch downpipe - screamer pipe - pipe from turbo to intercooler - intake pipe setup - power steering relocation kit - oil drain block off plate - coolant and oil lines Now onto the step by step guide (please add / correct me if there's anything I missed: 1. remove fluids, twin turbo pipes, pod filters and afm's 2. remove the factory coolant hardlines from the hot side. 3. remove heat shields  4. remove the downpipe 5. remove turbos and manifolds 6. remove factory manifold studs 7. clean whatever mess you have made 8. install power steering relocation kit 9. install new manifold studs 10. install new turbo manifold with gasket 11. install new wastegate with screamer pipe 12. install new turbo  13. install new coolant and oil lines  14. install rear oil drain block off plate 15. stop and appreciate that you now have a single turbo in your GTR 16. wipe away tears of joy and install downpipe 17. install the wideband sensor into downpipe 18.install pipe to connect turbo to intercooler 19 .remove stock boost solenoid  20. install new boost solenoid 21.  install intake setup 22. setup the rest of the can lambda kit with the ecu  23. refill fluids and hope for the best 24. ask forums for help with issues 25. fix issues 26. drive your single turbo swapped r32 GTR into the sunset. Doneeeeeeeeeee. Now I know this isn't detailed at all but I will be doing that when the conversion is done. I will be posting pics and any helpful details i can and ill make sure to fit in as much information as I can. If there's anything I should know before i do this PLEASE let me know. Stay tuned for what's next. Thanks...

      Nismo GT Pro LSD configurations

      By tidi0x · Posted

      I have wasted too much time on this, more than I am willing to admit. I hope someone can set the record straight for me.  I want to replace my Nismo (non GT pro, non GT) standard 2 way in my R33 GTST with a 1.5 way... Ideally I want to get an ATS 1.5 way Carbon LSD, but I don't want to reuse my 29 spline 5x1 axle stubs, and new 30 spline 5x1's are impossible to get a hold of ($$$), and I don't want to drop the cash on going to 6x1 stubs and axles ATM. Which leads me to the Nismo GT Pro 38420-RSS15-B5 or RSS20, as they come with new axle stubs meant for the diff, and is "Convertible" from a 2 way or 1.5 way to "Other ways", but that is where I am stuck as the documentation is a bit all over the place.  To sum up what I have found I believe the all the Nismo GT Pro PN's are convertible from 2 way, 1.5 way, and 1 way; but Nismo sells 2 skus (2 & 1.5) so people do not have to disassemble to convert it.  I found this thread on 350z but it left the question unanswered. https://my350z.com/forum/engine-and-drivetrain/620032-nismo-gt-pro-lsd-1-5-vs-2-way-and-torque.html  Essentially the way I think it all works out is like follows...  2 way  1 way  and 1.5 way would be the center pinion shaft in the 1 way block, but with the with the center flipped 180*. So the ramped side of the pinion would face the 1 way gate and act like a ramp.    I can only get my hands on the 2 way in the states, and I am not trying to get stuffed on tariffs by ordering from Japan or anywhere else. I want to confirm that if I get the 2 way I can convert it to the 1.5.

      Single Turbo Conversion On R32 GTR.

      By StevenJames32 · Posted

      Hi everyone, I have purchased my first GTR and I want to do a single turbo conversion to it. I've been doing as much research as i can and there are a few things that I can find and need to know. I need to run a coolant feed, coolant return, oil feed and oil return for my turbo setup. Here's what I know so far: On the hot side of the rb26 there is coolant feed, oil feed and oil return. Coolant return will be going around the front of the engine to where the thermostat is located. I will need to block off the rear oil return port. I will be running a turbosmart boost solenoid so any of the factory boost stuff wont be needed. Now onto what I don't know: 1. What do I do with the coolant / vacuum hardlines that run around the back of the motor?. 2. What do I block off or loop or move or remove?. I will be running the OEM intake manifold. 3. Is there anything in particular I need to buy for the cold side of the rb26?. I already have the intercooler and pipes sorted. If you have any pictures or information it would be appreciated. Thanks....

      "Cheap" bolt on turbo on RB25DET NEO

      By Murray_Calavera · Posted

      The fab work can be as simple as a couple of silicon hoses and clamps to the factory piping.

      "Cheap" bolt on turbo on RB25DET NEO

      Just sounds like either way you need to do some fab work to get everything to fit, so why limit yourself at that point? If the GCG high flow option is zero effort in and out swap though I'd probably do that. It's almost certainly lowest risk, lowest cost, etc. The HKS GTIII-RS option that Kapr mentioned is laughably expensive for what it is, they charge the exact same for two turbos on the RB26 so their margins are off the charts on that thing.
