My turbo has a loud scream too.

Its a hiflowed 25 turbo on a RB20, Spools around 2700rpm. then at 4000rpm it hits boost real hard and squeals real bad.

18psi of boost.

No shaft play.

Will a leak in the cooler piping show up on a boost gauge? or becasue the leak is consistant it will not vary the gauge?

I to have a whistling turbo that drives me crazy. noticed the whining and louder exhaust note after installing a stainless steel front pipe.when i take my foot off the accelarator it kinda sounds like theres some kind of back prssure if that makes sense. think one of the gaskets is stuffed or might even be missing a gasket. pretty sure thats wat my problem is unless any one can tell me otherwise?

ok guys, i just got my hi-flowed turbo installed, took it for a drive and its still making that noise, hypergear said it might be the gaskets any ideas, 2nd opinions? the noise is, putting my on the accelerator alittle bit it makes a tick tick tick tick, then hit boost, a high pitched sound.

Ill put a pint on an exhaust gasket. Manifold, or turbo-dump.

ya me to.

mani to turbo is the bet.

tighten up the bolts on the mani to turbo. also check the gasket, make sure it all still there. some of the gasket may have blown away.

tho looking at the above, you will have replaced the gasket when you put the turbo bak in...? same with the dump end?

boost leak? have you tested the it like this? http://www.youtube.com/profile?user=mighty.../13/atretf9u-Mc

i'd triple check for any leaks in the inlet

my squeals like a baby being used as a squeaking toy when coming onto boost, but the reasoning behind that is im using a panel filter (stuck a pod on it to test and it stopped) so possibly restriction from the filter onwards?

      WGNC34 - floor mats

      By soviet_merlin · Posted

      I'd be very surprised if you can buy new OEM mats. But if you can, I want some too!  Do you have links to the variations you found? Also, where are you located? I found that Nengun is happy to list items to purchase but when you do buy them you'll get an email that it's actually discontinued. As far as I know the variations in floor mats are different colour schemes as well as automatic and manual having a slightly different shape. The automatic ones fit into a manual car without issues, but I think you'd have trouble fitting the other way around. I have photos that show the shape difference if you care. FWIW I bought sets of used floor mats in decent condition at yahoo auctions.

      WGNC34 - floor mats

      By Marek · Posted

      Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.
