    For BB turbos to have a bearing failure in that sort of time frame it means your engine oil is contaminated and it does not related to how often you you service your car. In Garrett book this type of failure is not cover by warranty. Once you change the bearing catridge in them they will be good as new. You need a in line oil filter system setup for the turbo before you put new turbos back in. And we do not import turbos from Asian. Our turbochargers are made locally.

    Its really not the case of upgrading actuators. won't make much difference. What happens is the stock R33 turbin housing is too small, and it will build very high exhaust pressure with bigger turbo internals. So the manifold pressure it self over comes the actuator's spring pressure and force open the wastegate. Only solution is to get a .63 turbine housing.

    Nice, I guess Benji can't be bothered updating on both sites. It made 243rwkws at 20psi. The RB20's Tried now. He's Currently building a RB30 with 25 head. We are maing a .84 TR43i for his current setup. Should pull some decent results.

    The larger rear would be a .63 rear with RB25's bolton pattern. If you perfer 230rwkws BB GT2871 CHRA should do it fine. You can get that with stock turbo's rear housing. Stock R33's rear is only .48

    I've PMed you with our address. Thanks

    Any way adding some photos of the OP6 reared hi flows. This is a complete ATR28G3 high flowed into a OP6 Rear housing (note the mark on the housing) GT2871RS CHRA high flowed into R34 OP6 Rear with stock comp housing: This is a Custom made GT3076RS in a .63 Rear internally gated setup bolton to stock Manifold

    We do use 65mm Turbine. Need some thing to flow as possible in a small turbine housing. If you can get a OP6 turbine housing we can use ATR28G3 CHRA with 76mm comp wheel. That will be able to get you over 250rwkws. You can drive it on low boost no problem, as for the best results get it dyno tunned with Power FC and supporting mods. As for RB20 using ATR28G2 hi flow you can probably get some where between 200 to 230rwkws.
  8. hypergear
    The high flow will cost $800 plus $80 oil feeding line. We will be using ATR28G3's profile which should get you around 260~270rwkws (OP6 rear) with supporting mods at peak and not too bad down low either.

    I got a 71mm .60 comp / .58 65mm Turbine T3x internally gated turbo came off a SR20det test car. This is a very good responsive spec for a RB20det to make upto 230rwkws. Turbo's 5000KMs old, No shaft play, $700 with 12 month warranty. If interested send us a PM.
  10. hypergear
    It fits stock RB20 manifold with a 5mm spacer. Its not really responsive. But do make good power and torque.
  11. hypergear
    mmm.. The oil feedling line is half meter long. it runs straight into your block and to the top of the turbo between the turbo and chassis. Do not use stock oil delivery line as its got a oil restriction valve in it. stock T3x oil returne flange fits. I've got a mobile mechanic who works on site. If you want give me a call and I will pass on his contact information. As long as the turbo's getting enough oil flow its not going to get cooked. So do not use stock oil delivery line and fittings.

    Its a T"D"O4 with out the "D". Its a 57 trim T04E in .63 rear housing with .50 Compressor using 76mm comp wheel. Assuming turbo is proper made, its rated 160Ps Diesel application or about 260RWKWs on 98 patrol application.
  13. hypergear
    You can check for a OP6 rear. We will have the the bigger rears soon. The engineering place just take their time doing it. Hopefully be available in Mid May.
  14. hypergear
    Thats abit of too much play if you can manage to get the comp wheel to touch its housing (over 20 thou). Do a check up before putting it in to your car.
  15. hypergear
    Should be able to give a 7% discount for a minimum of 10 orders. Thats about the best We can do to have them made.
  16. hypergear
    depends on the noise it makes. The Shinnning noise is normal, If its making a Zzzz... zz... noise, very noticeable when you switch off the car then it means bearing cartridge needs to be checked.
  17. hypergear
    Stock injectors gets maxed around 230rwkws. Should see 220rwkws no problems. The TR43G2 is some thing to get if you are targetting about 270rwkws. Its running off a .63 rear. It will be making more power then the high flow. Or you can go for the TR43i which is made to archeive 300rwkws if you have cams and injectors upgrade in mind. For the CT20s we can also high flow them with ATR28G3 CHRA. which can produce about 260rwkws on a stock 1JZ. The GTR high flows will be using the TR28KAI's CHRA. They produce about 550HP as a twin.

    Its a ATR28G2 CHRA. using the GT2871RS Comp wheel. It might be in a None OP6 R34's rear housing. The comp wheel is not big enough to surge and we’ve opened up the air gap to avoid surging. Its been dynoed 233rwkws in smaller R33's rear housing at 1.1 bar. It doesn't seems to be a turbo issue. Check in take pipe, EBC, timing and tune.

    Below is a dyno sheet with Boost map of The ATR28G3 based on a worked 1.8L CA18det starts from 17psi to 24psi in a .64 T28 rear which is roughly size of OP6 (I don't think they are .63 thou) T3. This might not be relevant but I don't currently have any data of it running full potential on RB25det engine. RB25det Neo it should pickup roughly 20% more in response and 10% in power.
  20. hypergear
    excellent result. I believe this is with the Neo's OP6 rear housing?
  21. hypergear
    They can be water and oil cooled depends on customer's request there is no extra cost. Stock injectors and AFM can archeive 230rwkws max: TR43 (old version) on R33 Rb25det @14psi. With FMIC, exhaust, Pod and Dr.drift's tune.
  22. hypergear
    I really don't see why they can not last 200,000Kms. They are build using Garrett parts and some are using complete Garrett CHRAs. Work has been carried out with very well know turbo builders and engineers who's been building turbos for more then 25 years. Our job is getting every one working together to produce a quality and affordable product in Australia.

    Well come to profile a turbo it all depends on what the customers want. Some just want bit over 200rwkws with stock response and some want power and etc. But it all depends on the type of Turbine housing that people bring in for high flow. Small R33 turbine housings probably can only push out 240rwkws wither the bigger R34 rear housings get maxed close to 260rwkws. Also have to be very careful about the back pressures with the high flows, if the turbo profile is too big for its housings then it will create high exhaust pressure that pushs every thing against the comp housing. The thrust bearing is made to stop that but if the pressure is too high then the bearing will fail.

    Ball bearing mainly fail from oil contamination we've had few come in for repairs and even had one failed on our test car. They all Garrett turbos, Its not the quality of the oil. Its more due to the "mass" travelling with the oil. They needs to be filtered out before enter the turbo. How ever this does not happen often. I guess the main idea of going through the high flow is to get rid of the stock ceramic turbine wheel. 360 degrees thrust bearing does not make the shaft spin faster, Its more reliable at high boost. For sleeve bearings turbos out perform BB turbo. here is a classic example: Our ATR28SS vs stock RB25Neo BB turbo:

    Well the other slightly cheaper option is to high flow your existing turbo with Garrett GT2871Rs CHRA. The BB CHRA will spool up slightly quicker as there is less friction. The downside on a ball bearing turbo is in the oil purity but you can run in line filters to solve this issue. As in terms of sleeve bearing turbos not be able to spin at high RPM this is not true. It depends on how much tolerance on the balancing, the material mixture and treatment of the bearings, seals, and the perfect design of the actual turbo. That determines the performance and quality. There is no reasons that a sleeve bearing turbo should not perform as in the same standard as a ball bearing turbo. if 230rwkws is all you looking for its achievable with our high flow (date is with slight exhaust leak):
