noticed on weekend when car reaches 8 to 10 psi of boost i get this weird noise all of the sudden.... it hard to explain its like a metal screeching noise......car runs fine. only does it on higher boost......car has stock turbo running 11psi from turbotech boost valve...could the turbo be on its way out or a boost/vacuum leak?

Could be many. I had the same noise though and all my bolts holding the turbo to the manifold had worked lose and the gasket wasnt sealing.

Luckily the gasket was still fine and a simple socket on the bolts fixed my problems :P

Check all your gaskets for one.

+ 1

and check the turbo for shaft play while you're down there.

oh the joys of imports. Pretty sure its not the exh manifold on mine, looks pretty solid on there, but will go out n have a poke around the engine bay in a minute, got most of the leaks i can find fixed, just have to do this V-band!

I actually thought that KKR turbos were meant to scream on high boost for some reason lol ;s

I had to put the heat shield off and walla. Could move the turbo up and down. Once it was all back together its amazing how quickly it builds boost. I guess over time you dont notice your reponse slowly dropping...

Thats probably the more extreme case, but the little lugs just couldnt keep the nuts in place.

If looks could kill... Dosent hurt to put a socket on and see, mine was finger tight on the last 3 (near No 6)

    • I replaced the whole clutch line with the chase bays braided hose, I think it removes that loop, is it the short hose that comes immediately off the slave or is there a drawing in the manual to find what you’re referring to? It was just re-bled when I upgraded to the nismo slave, old slave worked fine but I thought that might help, didn’t change a thing. It’s like the first half of the pedal is pushing air and then when it finally actuates the master the friction zone is tiny. Makes it practically impossible to launch the car
    • Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.
    • I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it
    • If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣
    • I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.
