R33 Turbo 'clicking Noise'

2 problems from 2 different skylines.

1 First problem is when my friends S1 is underload and boosting a rapid clicking noise can sometimes be heard coming from where the turbo is. This only occurs occassionally however more so when its colder or higher boost is run. Just your thoughts on what it could be thanks.

2 My other friend has a series 2 which recently had a bosche 500hp rated fuel pump installed after the stock one failed and has noticed at about 4500rpm the engine begins to struggle with something and shudders when the foot is to the floor. He took it to Toycar and they said it was because he didn't have enough back pressure from a turbo back 3 or 3.5 inch exhaust. Just wondering if anyone has any other theories as i know plenty of skylines with large after market exhausts that don't suffer from this problem.

Cheers for any help

Thanks for the help guys i think i have the Series 2 problem figured out with a little help from Mick, thanks mate.

As for the series one clicking noise i'm still unsure. Almsot sounds like a car with a flat battery trying to turn over and it just clicks if any one knows the noise. Or the compresser or impeller clipping a wall, which i know it couldn't be.

The car was recently serviced and tuned running at 9psi

Mine does this too... I'm running an apexi turbo tho..

What boost controller is he using? It sounds like a relay clicking back and forth reeeally quickly aye.. .maybe 20 times a second?

Yeah i'm running the Apexi Power FC Boost solenoid kit.. Its ticks like a little bugger when on boost but i can hardly hear it over the exhaust/turbo whine anyway! Im pretty sure there is nothing wrong with it...

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
