lol! I wonder what is 'normal spooling noise'? Can anybody with a S2 that is 'normal' be bothered to record the turbo sound on boost? That might give those of us who suspect something is wrong a better idea... just a thought... objviously if you have an exhaust which covers it up that might be hard

I've still got the stock system. I've just never paid attention.

I'll endeavour to 'listen out' for what is normal and try to report back here.

:whistling:

the turbo shaft should not move more than 1-2mm in and out, and less than 1mm side to side. any more than that and it is on the way out

Thanks Duncan :thumbsup: That's good news.

When I had mine apart I'm pretty sure it had less than a milimeter; will try to check again. I could feel no play side-side.

Hi all

I have a S1 until just recently all I had was a nice turbo whistle. What I had was a very loud sound something like a mettle Bering grinding away at high revs. It turned out to be the exhaust manifold. I had two broken studs and the manifold was loose. I tightened up what I could now we are back to just the turbo whistle. I am doing some work on the car the week after Easter so I will try to fix the two broken studs then.

cheers

Oh, broken studs... :( good luck hope you can get the old ones out

Is an exhaust manifold gasket really $94 from Nissan??? Think I will look at aftermarket ones if I ever need one!

Hi All

I am not looking ford to working on the broken studs but it has to be done. I am hoping that the other 10 will come out easerly (If 2 are broken the others may be close to being in the same condition hence the reason for doing the lot).

I thort that $94.oo sounded a bit dear but I got it anyway

Cheers

:P

Hey Reuben what can you hear :P ?

My turbo is pretty noisy to my ears; I can pop the bonnet and rev it a little and it sounds like a noisy fan. When it's making full boost (with the high boost mod, so it happens at ~2,250 RPM and there's less engine noise to compete with) it sounds like a pretty loud noise, bit like a jet plane taking off but not that loud. Not loud enough now for people on the side of the road to hear - I don't think - but disturbing. Dunno if it's normal... will try to record a sound clip for you all...

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
