i agree with dave

there are lots of cars that run bush or journal style bearings and they last 100,000+

i dont suspect the bearing type would cause what you have experienced (unless installed incorrectly etc)

SOUNDS VERY UNLUCKY

it could be that both the highfows just havent been up to A1 standard

my slide highflow hasnt missed a beat in 18months of 1bar action

and that was with a dodgy-brothers backyard install job, where 1st fireup spat all the engine oil out lol (nut on oil line not tight enough)

make sure the oil is completely unrestricted from engine to turbo and back again.

Id suggest to get a brand name BB turbo this time round, such as a HKS 2530 for lighting response and 230rwkw (lets face it who needs 270+ lol) or a 2535 pro for more power if wanted.

search the net and you'll find a decent buy. BUT - what ecu setup are you running? have you got the z32afm, injectors, etc etc to use a 3071-turbo at 270rwkw?

anyway....bad luck, but good luck for the next one

Sorry to hear that mate, thats really bad luck. Go the 3071 or the 3076 ball bearing next time and you will be alright. I have been running a gcg hi flow for a couple of years and still all good. Unless both turbos were not rebuilt properly.

i am running all the supporting mods like power fc, 600cc injectors,z32 afm, tomei fuel pump, blitz fmic and all that.

i have supporting mods for 300rwk just incase i ever wanted to upgrade in future.

looks like the time has come :D

My slide highflow is still running awesomely as well....my one was one of the first batch so probably had extra love during manufacture :D

Seriously though, when I dropped the dump pipe of recently, it had less play that the original R34 BB turbo...which was also bugger-all

R33GOD, you haven't got an issue with the oil gallery that feeds your oil pressure line by any chance...2 turbo's on the same block spells an underlying issue.

i dont know. all i know is i used larger braided oil lines as i was told to.

would a dying oil pump be the issue??? (seems fine on the oil pressure gauge) what else could it be if this was the case??

Dont know if any of you have noticed, but the ones that keep breaking are all journal highflows..

Random? I think not..

Nothing to do with the cartridge (bearing) type :D

Without the failure analysis report from MTQ (post up when you get it) a lot of stuff will be speculation

well said dude,mine has been on for about 14months,done 18k,not a problem,will be going on my rebuilt motor,hoping for 350hp at wheels!have new denso highflow fuel pump in car,will get 550cc injectors,motor will have forged pistions and good set of conrods,so dont have to worry about it when putting a even bigger turbo on it if turbo blows,which i think wont happen!

i am stuck in 2 minds for these internally gated turbos.

gt3071R or gt3076R. Do they both come with .72 exh housings?

Just go have a look at the Garret Website mate! Got all the info there for ya!!

http://www.turbobygarrett.com/turbobygarre...R_700382_12.htm

thanks for those pages but i dont know what im looking at.

what means what? is the exducer the rear housing size?? a/r?? it has 2 sections: compressor, and turbine.

this is the 3071r :

GT3071R COMPRESSOR TURBINE

Turbo CHRA

700382-3 700177-3

Wh Dia Trim A/R

Ind Exd

53.1mm 71.0mm 56 0.50

Wh Dia Trim A/R Type

56.5mm 84 0.64 Wastegated

and the 3076r

GT3076R COMPRESSOR TURBINE

Turbo CHRA

700382-12 700177-7

Wh Dia Trim A/R

Ind Exd

57.0mm 76.2mm 56 0.60

Wh Dia Trim A/R Type

60mm 84 see below see below

someone please educate me on this.Ive only ever ordered hiflows..just cause they are bigger.. which one do i need for the power i want? i know i definately dont want the smaller rear housing or the biggest. something with fullboost by 3700-3800 where i can make 260-270 odd at 15-16psi.

you have very low expectations.

3076 will have that response and make a fair bit more power

3071 will have significantly better response and make that power.

Why 15-16psi? Thats not a lot of boost. Id suggest cams if you want to gain power but still run lowish boost.

The 3071 cart you have listed has the cropped turbine. With your reference to the .71 housing i assume you are chasing one with a copy OP6 housing? Thats the right cart for that housing. SimonR32 has some good results with that one.

thanks for the info guys.

i do want to find this problem of comp wheels blowing. would a modified stock bov do this as it always compressor surges no matter what?? i have blocked the bleeder hole in the stock bov and squashed the bov right down..

oil pressure is fine and oil color is perfect.

i just dont know where to begin to find out why this is happening or if its just another dud turbo..

im really keen on the 3076r at this stage. with the .7 rear housing.

do they come with that size from garrett ?

only thing is, would it require a specer to the manifold as it is still going to be low mounted

    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
    • I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
