    At this stage for dyno sheet I only have one with a 1KG actuator, not a very good boost controller either. http://www.digi-hardware.com/images/dynosh.../atr43360hp.jpg The best result a customer had was 282rwkws on 17psi with a strong actuator. But have not yet sent me his dyno sheet. A/R generally stands for the geometric characteristic of the housing. Bigger housings with greater A/R No. flows more, greater top end power, more lag. Small turbine housings picks up better response, but less top end. All turbine housings are made and machined here with cast steel with mixture of inconel.

    Well the boost pressure drop depends on the turbine housing pressure and the wastegate's spring load. Most of .63 and bigger turbine housings used on RB25det can be internally gated with a high pressure actuator to hold boost curve steady to certain point (18~21psi). Most of turbos we built or high flowed are fitted with a standard actuator. With high pressure actuator below, I've tried it on my own and also few customer's R33s which did manage 21psi flat using .82 turbine housinged ATR43G3 turbo. This actuator Cost $150 additional with all high flows and brand new turbos: To build a sleeve bearing GT3076 spec turbo in .82 turbine housing with OEM bolton pattern we charge $1450AUD including oil feeding line. To build it with Garrett GT3076 Ball bearing CHRA using our .82 turbine housing with OEM bolton pattern is $1850AUD.

    The CHRA as in the same spec. Just the housings are different. How ever we can build those turbine housings to suit GTR upgrades.

    BB units shouldn't rub against housings unless there is a bearing issue. If you an not feel any shaft play in them it means the wheels are broken from foreign objects. Which means they only require a new comp wheel which is a pretty cheap repair. If the bearings are worn due to oil issues (which can only be this issue) then this repair will be very costly.
  5. hypergear
    Including the .70 comp housing and the anti surge slots, it will cost $1230 to carry out. If your current internal gate works then your are still be able to run it internally gated.

    No need. easiest way is to insert a 2.5inch metal pipe into the stock intake pipe, then clamp it over to the turbo with a 3inch rubber hose. But steel intake pipe is perferred. Also do make sure the inside of the pipe is 100% clean before botting it on.

    Disco: Since we are talking about the turbine wheels and obviously your self works in the turbo industry. Would you think the Factory Garrett GT30 turbine wheels would out flow the TA34 turbines with crop for high flowing applications? The GT30 turbine is obviously lighter in weight and spools faster. Just have to go through the trouble of installing a custom shaft for sleeve bearing high flowing options.

    I actually got some 1 bar and 1.8 springs made to suit HKS 50mm gates. If you want PM me your wastegate spring Dia. I might be able to help you out with a lot cheaper solution.
  9. hypergear
    I thought the VG30det's got a .63 turbine housing. If its true high flowing it with a Cropped TA34 turbine with 52T 76mm or a 56T 71mm comp wheel using a .60 comp housing and a strong actuator should crack just over 270rwkws.
  10. hypergear
    Very slightly higher trim on compressor wheel, Anti surge slots for the noise, and bolton turbine housing for R33's manifold and dump. It should make just touch bit more power then stock GT2860RS
  11. hypergear
    Here are some updates. I spent a day working on this and turned a blown R33 turbo to a sleeve bearing HKS2530 (Yes even machined matching compressor trim). By calculation it should produce exact amount of power and response as the actual 2530. Its for sale complete with $1000 with oil line and high pressure actuator (1.2KG) for how ever's interested to provide some dyno sheets. From calculation this turbo is good for a super responsive 220~230rwkws on about 15psi of boost. The cost to high flow any R33 or R34 turbos in this way cost $1050 including braided oil feeding line or $1150 with high pressure actuator.
  12. hypergear
    Standard VG30 turbo is good for about 210rwkws. Once high flowed to 3076 spec its capable of about 270rwkws.
  13. hypergear
    Yes it should. I fitted one to my own car and it seems to be ok. Well you are welcome to send the unit back to swap for a bolton turbine housing.
  14. hypergear
    you can run around 12psi for little bit. No guarantee the turbo can last. With 98 fuel Stock engine and management should be ok.
  15. hypergear
    The HKS250 Is not exactly a GT2860R. Its running a GT2860R"S" CHRA with a 64T 60mm comp wheel. (GTRS turbine wheel is different) Well if you have a working GT28R we can machine your stock housings to suit its CHRA, Still be a cheap option for around 200rwkws.
  16. hypergear
    If the turbo is working I suggest to sale it and we can buil you a new one. But if its dead we can high flow that with a Garrett GT3071 chra. will have very similar sort of response, and maxes at about 260rwkws. This will cost roughly $1350 mark.
  17. hypergear
    We can modify your R33 turbine housing for lot better flow which class under the PU highflow options. So basically yes we have to modify every thing on it. The VARA is still under development at this stage. will be ready for public soon. Excellent result Lowrb. Please post dynosheet when possible. Thanks
  18. hypergear
    Well visually the high flowed turbo appears to be same as the stock turbo. You can use your stock actuator. Or we can modify your stock actuators actuation bracket to suit a high pressure actuator.
  19. hypergear
    With the high pressure actautor you will be seen a lot more steady sort of line with out the drop. and will be making more top end. Once high flowed you basically get a brand new turbo back in your stock housings so it doesn't matter if your current turbo is blown or with heaps of shaft play. The old and blown CHRA in your stock turbo goes into the bin unless you want it back.
  20. hypergear
    I would say around 280rwkws with high pressure actuator. full boost by 4200RPM. be just like this one here: (Dynosheet below is running a normal 1KG actuator) http://www.digi-hardware.com/images/dynosh.../atr43360hp.jpg and No we can not get standard size wheels in steel.
  21. hypergear
    We actually build a brand new turbo core with bigger wheels, then machine your stock housings to suit it. We only use steel turbine wheels. So are you actually getting back a brand new turbo inside your factory housings.
  22. hypergear
    Standard from $800 + GST + oil line $80 = $960 Powered up high flow from $1100 + Oil line $80 + $150 High pressure actautor = $1310
  23. hypergear
    Probably not at this stage. They are too small to work with.
  24. hypergear
    If your turbos is still making boost without too much noise its lot cheaper to just get it rebuild with a new set of Garrett bearing kit which will cost only $660 assume your stock wheels and housings are in ok condition. We will email you a inspection report before starting any work. So you know what you will be paying and why your turbo has failed.
  25. hypergear
    Convert that into OP6 R34 turbo cost $1000 including braided oil feeding line and oil drain adaptor. To do this we have to modify T28 bearing housing to suit a T3x pring turbine housing.
