Hi, took my car out today.... put my foot down, as u do ... and anyway I could hear this weird air whooshing sound under boost, I popped the bonnet and found something apart, so I clicked it back together and went for another spin, same noise.

When I checked under the bonnet again the thing had come apart once again.

Ok so I dont know what its called but I took some photos, hopefully someone can help me, hopefully this is the cause cause it looks like i can tape it back together but I dont wanna cause im not 100% sure.

all it is is the charcoal canister feed from ur throttle body.. just super glue it back together, and it should be ok. its popping apart under boost.

ok well i just superglued it back together after giving it a good clean, going to take it for a spin in 30 mins or so ...

you think this is the cause of the whistling noise tho ?

Ok so i glued it all up and took it for a spin , same noise tho :(

car still goes hard and seems like the boost is a little higher .. or takes less time to get to full boost...

anything else i can try before i take it to the shop?? :)

you can check all your boost lines. maybe one has come off? its happened to my car a few times, but easily fixed with truckie ties (cable ties). IF not that then maybe a loose gasket? i had a 180sx which the exhaust flange gasket popped making it have a whistling noise.

oh the possibilites......

what it sounds like is one of two problems... 1) vacuum lines 2) intake piping

1) what i do to find the whistle is spray each line individually with some hair-spray. so spray one, wait for it to dry (10 seconds), rev up the engine... if it still whistles, check another line/connection. keep doing it until you find which one is giving you grief and then replace the bad one.

best part about hairspray is that it's water soluble, it's cheap, non-corrosive and hardens very fast.

2) I have had less experience with this issue, but the best way to check is to pressurize the whole intake system without the engine running (valves sealed and no other noise)... you can do this by using a valve-stem mounted inside a piece of capped off PVC piping. Just place the capped off piece of PVC piping with the valve stem in place of your air filters (cap off one of them), pressurize the system with a bicycle pump and listen for any leaks. you may have a cracked coupler that's causing air to whistle as it quickly gets vacuumed into your piping.

I recently had something like the whistling noise coming from my engine and it quickly progressed to a heavy whoosh. no boost issues, no sputtering, nothing. turns out one of my intake pipe clamps came loose and with every close of the throttle I wasn't using the BOV but rather a piece of piping was completely coming off and then sealing itself again.

check those two possibilities and see how things turn out :)

Hey really weird ... took a mate to show him the noise ... gave it a little aswell... dropped him home, went inside for 5 mins anyway when i drove off the car sounded ok ?? no more whistling ... so i reved 2nd gear out and it sounds ok now.

This sucks in a way cause i want to know what it was :P ... can anyone suggest anything lol ?? :)

I have a similar problem, running a SR20 over 10psi the turbo almost sounds like it is spoiling harder or with a distinctive whistle. the car still boosts the same but the noise is there, started when i had to drop the clutch comming out of a servo one night

    • 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"
