hey guys, was at a mates house today and decided to put in a manual boost controller, went for a drive, put my foot into it just a little, it spiked... so i pulled over, wound it down... got back in the car, cruised for about 2 minutes then got onto a straight bit of road and gave it another squirt... it almost choked up, coughing and spluttering and so on, took my foot off... when i went to put my foot down again, i hear a noise like a siren, i look around only to find the sound is coming from my car... so now i cant make boost, no matter how hard my foot is on the accelerator, it sounds like its coming from the inside the pod filter... so i go back to my mates house and pull it apart, all the way down to the turbo blades, checked it and nothing caught in there or any of the piping, put it all together again but still making the noise... i took the boost controller off but still it makes the same noise...

SO... was just wondering if any of you guys have ever had this issue or know what it is at all... just lost my job two days ago so cant really afford to go and get another one... any help would be greatly appreciated...

Cheers

Guy

maybe, was a bit dark to finish the elimination process... so tomorrow morning ill check piping and all... spoke to hyperdrive and they reckon might be a leak on the manifold or exhaust somewhere... not sure, but the noise is really loud, like almost copper siren loud... just odd!

Be careful. If its the bearing then the turbo will be spinning out of alignment. Hence the fins are spinning into the housing. Slowly feeding ur engine small metal filings. Did the boost gauge move to like 10psi? or nothing? Blow IC piping = no + boost

yeah it did before it stopped... now it just sits on 0... wont go past it

If it was blown turbo, wouldnt there be smoke?

    • I have done smoke test and can’t see any leak on high or low side.   checked pump and fluid can flow through. Removed the high pressure from steering and did smoke test and same on low side, no leak.   puzzled. Thinking why if it was all ok it suddenly went as car was off road for a year. Don’t want to disassemble pump yet as i can see fluid / air( compressor) can flow through with no issues
    • Which manifold mate? Meanwhile......Mark is wondering how bonnet vents would look on the NC 🤣
    • Actually,  just remembered there should be info in the threads (somewhere) about swapping to a manual steering rack and deleting power steering all together. 
    • Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open
    • Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.
