Hey peeps i've got an r32 gtst with an rb20det. When i go to put my foot on it, it starts to spool but it also sounds like its leaking boost from somewhere as there's like a "pshhhhhh" noise and it seems like there's a little lack of power. Has anyone else experienced this or know what it could be?

what boost is displayed on your boost gauge?

do you know what a turbo sounds like?

11psi. which is what its set to. yeah this is a really loud shhhhh noise tho..doesn't sound like a spool unless i'm on crack and have got it completely mistaken..but it feels like i lose power

If you can see 11psi, then "if" there is a leak, it is after the turbo.

so being an RB, most probably a gasket leak at the turbo manifold.

My guess from this side of the monitor is that you have a bolt missing from the turbo to the manifold.

you might be able to just tighten replace and tighten it and it will go for a while longer.

"IF" there is a manifold leak, and you leave it, it will get worse as the whole in the gasket gets bigger.

eventually, it will start to sound like a lawn mower when idling.

"OR" you are most likely on crack and it's just the sound of an RB20 with exposed pod filter.

ok cool. i'll have a look. I think everyone may be right i think it is probably only the pod induction. I was just wanting to make sure because i'm selling it..i'm not the most technical minded person and sometimes i can be a bit thick

      My extinguisher mounted like this unscrewed a little (Maybe from the chair sliding forward) and dumped a bit of white on my mats. I'll need to get a more narrow one for future.

      I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)!   I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.

      I know which one I'd prefer to have in my garage, and which one I'd actually drive as intended

      I definitely agree with you there - I never click on content for cars I would never ever be able to get or compete with/against/be seen next to. Seeing a MX5 compete with a FD RX7 will make people upset though, for sure. Even in 2.5L Turbo form which is pretty grass roots. (or at least as grass roots as classic cars can be) Yes we're all classic car owners now.
