my r33 gtst has blown another bush bearing hiflowed turbo. only 3000k's old. never been boosted past 14 psi.

the comp wheel has disentergrated but no shaft play and rear wheel in tact. still spins perfect. and nothing has gone through the turbo as the afm and panel filter are still in perfect order.

the last turbo that had failed was due to apparent oil contamination but i done an engine oil flush, new filters, and braided oil lines. so i dont think there was a chance of that happening again. made damn sure of it but this new one has gone on me. so upsetting. i was told it would be perfect and up to spec and should be fine for 18psi if i wanted to boost the turbo more at a later date.

i hope the 12 month warranty will cover this.

as i am in the hunt for a new turbo setup,( ball bearing this time ) what would best suit me to reach a goal of 260-270 rwk on say 15 psi that is a direct bolt on application for my r33 gtst.

thankyou.

i think the cause of the turbo dying was too much preload off the actuator???

i never had a boost controller. had to boost the car like this.

another tuner i took it to said whoever tuned your car has put too much preload on the actuator.

Too much preload wont kill a turbo unless it cant handle the boost you are running (which is so unlikely its not funny) :down:

So whoever was feeding you that - is full of shit :(

More pre-load the better if your running higher boost levels. Leads to less chance of boost spikes and creeps.

looking at a garrett 3071r turbo... will it make about 260-270rwk without ringing its neck. i dont know much about specs so if someone could reccommend a turbo for me for that power running about 15-16psi would be much appreciated

You run a BOV as opposed to a so called 'dose' pipe or none at all?

i run the standard BOV. the bov is slightly squashed to incerase spring tension ( was told to do this on the forums).

was getting compressor surge still. not huge amount though

There's nothing inherently wrong with a bushed turbo. You don't see 15 year old s13's spitting out compressors every 10k.

My last turbo was bushed and that copped a flogging for 2 years that i owned it without missing a beat. It wasn't water cooled either. Hopefully the new owner gets plenty of enjoyment out of it too.

I can't really add any more at this stage other than you are either very unlucky, or you have missed something on both your installs. You don't still have the stock banjo at the block end or something like that? Have you tried cranking the engine with the oil feed off and see if it is getting oil through?

There's nothing wrong with a k&n panel. I run one myself as do numerous other members. What sort of intake pipe do you run? is there evidence of paint/chrome/rust flakes on the inside?

The 3071 seems to be the turbo of the moment. I have a few teething problems atm so i'm not going to say it will or won't meet your expectations, but an initial lazy run of 260rwkw on 16psi looks promising, as does the boost response if you can keep the gate closed. I just have to work through a boost control issue at the moment which i strongly suspect is dump pipe related and hopefully it will be good.

      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.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.
