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

this time im gonna do it right

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.

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
