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

    • When you crank your car, and hit it with a timing light, can you see a steady crank timing?
    • Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).    
    • Car is on factory injectors/z32 maf/ q45 throttle body/ z32 ecu with nistune 
    • Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov
    • yeah I was shocked when I checked my spare OEM on and as below that's how they come from Nissan. (side interesting note new NEO gearbox and replacement park lack the brass bush on the tips and its just all alloy) unsure about damage to the box currently back at 1110 to be pulled down/inspected and selector fork replaced as he built it previously and given the never before seen failure on his billet forks he is replacing it under warranty. He said he has used always OEM the keyway tab without issue for years so it could be an unlucky coincidence. I did talk to him about the sharp corners and stress concentration too. Re: hard shifts i got 7+ years out of the OEM one and the fork itself failed not the keyway. so could be bad luck as I said or an age thing + heat cycles in box and during fabrication of billet?
