    Yes but that was in stock R33's turbine housing. Now they are running in a .63 T3x rear housing, The spec of it is very similar to a GT3071. So it should make around 260rwkws at 18psi of boost on 98 fuel

    Well stock turbo won't make 520HP. Bigger turbos will creat more lag. This is a G4 profile, made for 300rwkws. We also have this in G1 and G2 profiles which are rated 350HP and 450HP. The G1 would have very similar response as the stock turbo to produce max of 240rwkws, G2 is about 300RPM laggier but but its good for upto 270rwkws. Price wise This turbo is $1300 to complete. With normal Turbine housing which comes out in a Vband rear is $1050 internally gated. or $950 externally gated with a 5 bolt flange.

    The Very first ATR43i 520HP G4 in T3 .64 Turbine is complete: We'll be making few more different A/Red turbine housings in the next few weeks. We will also be engineering a 650HP profile CHRA to suit a .84 Bolton Rear housing.

    Is this a proper build turbo or a ebay special? assume is a proper build turbo. The other reason for it to leak would be oil drain related. The turbo runs off a gravity drain system, So when you do see smoke it means the drainage cell on turbine end of bearing housing has been filled. unless bearings are worn which allow movements to the shaft its very rare for the seal it self to fail. For ebay specials. It could be vibration from bearing and shaft tolerance, broken seals from bad materials, faulty bearing housing, bad oil division and so on. This is what a oil seal looks like:
  5. hypergear
    Well oil seal it self won't fail. Its just a stainless steel circlip. Its the bearings that fails, Then it lose control of oil flow and cause 0il to hydraulically leak through the seals. To check the condition of turbo, simply move shaft up and down then left and right for shaft play. Should not have any thing above 20thou.

    Today got the turbine housing made. It is .86 in a T28 which is equivalent to a .63 in a T3x. It is bolt on to stock T3x manifold and 6bolt dump.
  7. hypergear
    Yes. Should have one made today in .63 rear end. Price wise they are $500 each. I need your turbo back to match the profile to suit its turbine wheel.
  8. hypergear
    Yes This model made for bolton application on a RB2x engine. There are 4 profiles for any thing from 240 to 300rwkws
  9. hypergear
    Compare to ATR28G4 it has lighter turbine with shorter bearings. So it should have slightly better response. I might update this CHRA into the ATR28G4 once its been evaluated. Turbine housing is getting made. I'm going to swap this 2x with my existing high flowing customers. probably Geraus and SS8_Gohan for some dyno and evaluation results. For time been we will still be using proven ATR28 CHRAs. Price wise I don't know at this stage. depends on how much it cost to build the rear housing.
  10. hypergear
    Yes that can be done. Just file the bolt wholes on the actuator bracket 5mms down, then pre-load the actuator about 4mms and you can adjust to get around 0.9Bar of boost reading on the gauge. We do that to all the high flowed turbos that we make.

    This is a prototype ATR43 G4 520HP CHRA. It runs on shortened bearings and weigh reduced turbine for maximum response. engineered to produce about 300rwkws at 20psi on .63 ATR43's turbine housing using RB25det engine with supporting mods. The smaller one on the photo is ATR43 G1 350HP CHRA. Its made for 240rwkws with excellent street response.
  12. hypergear
    ATR28 is also avaialble in .58 and .63 T3 rear housings to suit Rb's manifold.
  13. hypergear
    The .63 TR43i is made to produce 300rwkws. For the RB20det engine .58 T3x ATR28G3 internally gated is a better option. They can make around 260rwkws on stock RB20det with excellent on road response. Price wise it cost $100 more. In Garrett range its some thing in between GT3071 and 76.
  14. hypergear
    Its similar sort of CHRA. Rear housing is different. It will be a.63 Rear housing. that we made our selves. I'm plaining to make 4 different types of CHRA with 2x different sized A/R housings. which are powered from any thing at 230rwkws to 330rwkws depends on driving ability. I will post some photos once I get the housings finished.

    The guy got EPAed and defected on the way back from SA. its going to be a while before it go back to the dyno. Hoo and by the way there are plenty of ATR43's progress. The laser cutters finally got our flanges ready. So just matter of putting them together now. should have 2x samples done by weekend.
  16. hypergear
    Well if you run around 10~12psi of boost with factory ECU is fine. The VG30's got .63 rear end which is very good for high flowing. But to get that 280rwkws you need injectors, fuel mods, ecu, afm and etc.
  17. hypergear
    I think HKS wanted that turbo to be noisy. see the surge slots on the comp housing. as in the angle of where they are and how they sits. this thing will be howling very loud when air pass by. Been told by our engineer that this turbo's going to make lot of noise. I sent the core to Garrett for bearing analyze and been told its fine before went ahead with the repairs. it should be all good.
  18. hypergear
    Just $800 to high flow. with the VG30's rear housing it can be high flow it to produce around 280rwkws with supporting mods. I haven't had VG30 turbos been BB yet. the topic says its VG30 ball bearing turbo. so maybe a unusual version.
  19. hypergear
    Its dead needs to be highflowed or replaced. BB turbos are not suppose to have any play. There are only 20thou between wheel so its probably touching its housing.
  20. hypergear
    Most people who brought in their dead skyline turbos for high flow said similar thing before their turbo totally died. Its good idea to check for shaft play and see it spins freely.
  21. hypergear
    Well depends on how cheap you can get the turbo for. You can bring us a 2nd hand T25G/T28 .64 turboine housing with your turbo and we can machine it to suit your new turbine wheel for about $150.
  22. hypergear
    For about 280rwkws with fast response you can try a 52T 76mm comp on a GT30 Turbine in BB assemble using .63 rear housing. Or .58 rear housing which would definitely increase response shaving off about 20KWs top end power. You can also replace the standard .50 To4E compressor with a .60 T04B comp. Which can also increase turbo response.
  23. hypergear
    Its funny how cops can find and EPA you on a high flowed turbo, which they are just identical looks to any other stock turbos. I also had a customer who got defected in Vic over a high flowed GTiR turbo that we worked on. I really believe they have X-ray eyes or some thing to looking through metal housings for bigger wheels. Nistune is good and cheap. You can get away from most of cops with it. But I don't think Matt have made one for R33 yet. Most people I know is running off a R32 ECU with modified loom.
  24. hypergear
    the stock thread is definitly M12x1.25. Not M12x1.5. Don't get the wrong one. We currently supply quite a few on weekly bases to high flow customers. The speedflow fitting is better to use compare to benjo bolts, The 50mm line runs between the turbo and chassis.
  25. hypergear
    We can supply you one for $80 is required. Its a half meter long dash 3 SS braided hose with one straight hose tail and a 90 degrees hose tail. 2x speed flow fittings. One in M12x1.25 to engine and the other one depends on the thread that is in the turbo. Factory turbo thread is also in M12x1.25 Factory oil line is held by a hollow screw, Once you remove the screw it comes off. If the high flowed turbo is using sleeve bearings, You will need to get aftermarket oil line or drill out your stock oil line's restriction valve.
