my r33 gtst needs to pass an EPA test and to do so i need to have standard boost control parts running. at the moment i have a duel stage boost controller and it runs fine with the duel stage. when i put the vac lines to the standard controller it overboosts. can someone tell me what vac lines need to go where? also i have made sure the plug that comes from the standard controller is plugged in and i have even tried another one from a mates car. could the wiring for the standard controller be used for the aftermarket unit? if so what should i be testing for with the multi meter? the after market controller has an earth wire and a wire running through the firewall and i cant see if the wire from the standard plug has been cut as it dissapears into a loom. any help would be much appreciated. thanks, brad (also my car has a standard turbo,FMIC and at the moment the airbox is fitted and i have checked for vaccum leaks)

You won't need a multimeter... the standard solanoid should give 5psi if it's not working properly, and 7psi if it is.

I suggest that your plumbing is not quite right... from the intake pipe down the bottom, the pipe should come into the bottom of the solanoid (I think.. if not, switch them around), and then the top one goes to your wastegate actuator.

i treid the lines both ways but i was a little worried id do some damage can anybody confirm which way they are supposed to go? also id like to know what im looking for with a multimeter with the wires coming from the solinoid as i said before i tried the vac lines both ways and i even tried another solinoid from my mates car which i know works.

from memory one of the lines was running to a T peice, also one line had a little restrictor in it, if thats not in the right place that may cause your problem.

Let me work out what needs to go where cos im in the exact same boat as you, i have a dual stage boost controller installed and i need to put the standard one back on so i can get it trough RoadWorthy.

Ok here is what i worked out on how to properly install the stock boost controller.

First off there is a hose from the actuator goin to a T peice, its only short and it has a yellow band on it because it has a brass restrictor in it.

From the T peice it goes to the BOV retuirn pipe.

Then from the T peice it goes to the bottom of the boost controller.

The last is a straight hose goin from the intercoller pipe to the top of the boost controller.

Can someone please confirm this for me, i just want to be %100 sure.

I mainly want to know if the restrictor is in the short hose coming off the actuator and goin to the T peice.

I hjope this helps, im %99 sure this is right which i would love someone to confirm this all for me ..

no thats wrong.

(if you have a front mount there will be a hose from the bov pressure line (the vacuum hose that opens the bov) instead of the intercooler pipe)

there should be hose hose from an intercooler pipe. this goes to a T piece. from the T piece there should be 1 hose going to the wastegate, and 1 to the lower hose of the factory solenoid. the top hose of the solenoid should go back to the intake (bov plumback pipe).

Ok this is straight from the Nissan Fast program, so thjere is no disputing it.

Top of the boost controller goes straight to the wastegate.

The bottom goes to the T peice.

One side of the T peice goes straight to the intercooler pipe.

The other side of the T peice goes straight to the BOV return plumbing.

Thats it, 100%..

I also found a picture in another thread showing the stock setup i described.

The restrictor is in the short hose goin from the intercooler pipe to the T peice, make sure you have the restrictor in place.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
