Hello

I am hoping that someone might be able to shed some light on the shiney new ticking noise coming from my turbo.....

i have just installed a new blitz dual sbc type R, at the moment it is in the off mode, which lets the car run at factory specs, 7psi, but when it's turned on and the boost is set at 12 psi thats where I am having issues, as the boost increases past 5 psi there is a ticking noise... it wasnt there before and it isnt there when the boost controller is off... any ideas at all would be great

thanks

Did you rubber mount the solenoid for the boost controller?

If not then it's most likely just the solenoid for the boost controller tapping against metal. I had the same problem with my Greddy EBC and just placed a piece of bike tube between the solenoid and the mounting surface.

yeah the solenoid comes with rubber mounts already attached to it, but it would make sense that it is the solenoid... i thought it would have been silent though?

did your tick change with the boost?

Does anybody have pictures of where you connected the tubes etc. from the stock solenoid? I am also wondering what I should do since I have a blitz intake pipe with the BOV fitted onto it. I have rifled every post on all the usual forums and can't find a good picture of the skyline with this boost controller installed.

are you after pictures of the tubes for the stock setup or for the blitz dual sbc? if you want a picture of the blitz i can post what i have, but i do have the tick problem still.... but only when running over 7 psi and it will be a week or so before i can take a photo

As for the ticking sound; is it actually coming from the solenoid or not???? Use a screw driver to the ear.

They should really only hum, or buzz - Describe the "tick sound - slow, fast, constant with boost, revs what...?

i dont think the tick is coming from the solenoid, but it has only started to do it since it has been installed, the tick starts when the engine is under load and the boost gets to about 5 psi, if i had to describe it i'd say it sounds like a sprinkler ticking off in the distance, i was thinking it could be the waste gate? but if it was the wastegate it'd do it on stock boost too, right? the noise gets faster as rpm increases...

my blitz ebc doesnt tick. it does have rubber mounts though so maybe thats absorbing it.

it really sounds like the solenoid from what your saying as it increases with rpm and only happens when theres boost.

whack your stock solenoid back on and compare.

my soleniod has rubber mounts, the stock solenoid doesnt make any noise, when the blitz control unit is turned off, it runs 7 psi, for the turbo to run at 7 psi the blitz solenoid still has to control the waste gate, but it makes no noise..... which is why i thougth i was the waste gate, but if it was the waste gate it would do it on stock too.... so it looks like i spent $500 to add a noise that gives me the sh!ts.. awesome!

I'm having the same problem with my Blitz dsbc Spec S. It was silent when i first installed it, however the following day the noise started after driving for 20 min. It starts ticking at around 3psi and stops at around 9. However It won't do it at all when the boost is set at 15psi (56%). Anyone know what could be causing this? (solenoid is rubber mounted and it doesn't sound like metal on metal...)

If its ticking like a relay noise

Its normal for a EBC. Plenty of threads on EBC ticking, all the same thing... its the solenoid working @ different rates

So i've seen after a bit of research... But why would it only do it on lowish boost settings (doesn't do it on 0/7psi) regardless of what the cacr is boosting at. i.e 15psi setting it won't do it in the 3-8 psi range. If it is meant to do it why doesn't everyone's solenoid do it? Is there just a lot of faulty solenoids going around with audible ticking?

The ticking WILL be coming from the solenoid, rubber mount it or deal with it!

It ticks (only once on boost not in vac) becuase its trying to close the wastegate because it has not reached desired boost level.

If you turn off the boost controller it will stop ticking to prove it.

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
