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.

    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
