thanks steve and luke.. we left it idling in the driveway for about an hour once first started up, and drove it gingerly for the 5 k's , but you still think the squealing is because we didnt prime them and the turbos are stuffed because of a split second without oil??

sorry for the blatant obvious, but maybe let a mechanic have a look at it before you go pulling a turbo off again........possibly needlessly

What area are you in? There's always a decent workshop nearby.

But also, can't leaky exhaust manifold gaskets make a car squeal under load? Thinking of cars I've heard around Malalla/Winton here.

Yup, mine has howling/squealing like a banshee at the October track day last year when the engine gave way, and it was due to a gasket on the turbo spacer blowing out.

Cheers guys !! Sled it's getting looked at right now, but the owner is a mechanic and we had another mechanic look at it last night, it could quite possibly be the exhaust manifold gaskets as when the new turbos were put on the old manifold gaskets weren't replaced (all other gaskets were though)

Hopefully thats what it is, I dont reuse gaskets ever, unless they are like just the joins in the exhaust or something, every time the turbo or the manifold comes off the motor its treated to new gaskets.

I think the gasket kit for the turbos didn't come with one for obvious reasons but I just think it was overlooked because of that reason. not exactly sure. and there's a lot of burning coming off the turbos as in smoke, would that just be due to touching every part numerous times with oily hands and it's simply just burning off??

Use the genuine Nissan turbo gaskets, a lot better then the aftermarkets, I have used the Garrett ones on mine and the Nissan ones are far better.

Also, did you reuse the copper washers or use new ones?

is there anything to do with a plug on the turbo? a drain of some sort that your meant to unplug?? or does this ring any bells for anything that might make more sense to you guys?

Hi pitch squeal, look at the induction side of the turbo's, the y piece between the turbos may be loose or gasket leaking you should be looking for a boost leak through a very small orifice had this on mine before.

Hope it helps

Word. Get the OEM VRK (?) set and you'll get every gasket that you need, to nissan spec. If its good enough for nissan, 99% its good for every other dude out there... only non nissan gasket I got is the cometic MLS 1.3mm head gasket....

I even have gaskets left over I reckon I'll eventually use - won't have to pay for the individual component when the 20 year old oem eventually gives way

    • 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...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
