    I really liked the way how the KKRs560 had the center divider grinded out for the internal gate to work. But either way that is not a "real" twin pulse housing. The pulse in the center must have the exact clearance to the turbine wheel as the rest of the turbine housing profile does (20 thou), with the pulse separated from the manifold all times. Realistically it needs two external gates and gets treated as "twin" turbos. I seen one ( I think it was a Toyota turbo) which got 2x wastegaes in the turbine housing as in one per pulse. It will has to be setup that way for the to work. To get that working the pulse will need to be twisted so it actually faces the dump pipe area, Will need a new casting and etc to get that working. But nothing is impossible.

    Thats ok, you can run as much boost as your engine's happy to take it. I will warranty the turbo no worries.

    Well you can start by checking engine oil level making sure it’s not over filled and the rubber on the hard oil drain pipe is not kinked or blocked. The turbocharger usually leak out oil from both ends if it can't drain oil fast enough or can't drain at all. Once above has been checked with any issues repaired, start and idle the car for couple of mints see if the smoke clears away. If not it would be likely been that this turbocharger needs a service, Do check out our turbocharger high flowing thread and alternative options available if that appears to be the case.

    Hi Dave: Yes standard high flow will make around 260rwkws mark after high flowing on stock manifold. You will need a 3inch metal induction pipe for this sort of power level. Std injectors will max around 230rwkws, you will need 550ccs to get up to that power level. The turbo will fit all factory bits excluding oil line after high flowing. The price is $960 including braided oil feeding line required and GST inclusive.

    For example: .82 rear housing using identical chra. Standard V Type A FNT. Use above .82 Type A V Type B FNT The power to response trade ratio after compressor maximization is 1:10 means the lost of every Kws can be converted to the gain of 10RPMs. Take example that ATR43G3 CHRA is capable of making 330rwkws pump, how ever based on factory manifold and internal gate restrictions it can only archive 280rwkws, resulting a dead weight lose of 50kws. Assume the maximum power level this turbo can reach based on factory setup is 300rwkws, I can configuration the fixed nozzle in my turbine housing for it to max out at 300rwkws while trade the dead weight power for 300RPMs of response, as shown on type B housing graph above.

    Once every thing tired and nothing makes a differences then you can have them removed send it to us for the FNT turbine setups which proven differences in response. I'm also personally interested to see the differences they makes on a GTR.

    The turbo is not expansive to produce. all I have to do is slot the .82 rear housing in the center and insert an divider then profile the housing to suit turbine wheel, and we have a real twin scroll turbine housing. How ever it must be used on a twin scroll manifold as well external gate (preferably 2).
  8. hypergear
    Yes that is. I'm recently putting in lots of thoughts into modifying stock exhaust manifold. All we had to do on it is basically mill out the top layer of the cast, weld in larger diameter of steam pipe and external gate port. Should be producing same results as any of the $1000+ exhaust manifolds, while probably cost a third of it.

    They are 1600 for the pair. Equivalent to 52t.

    Preferably Allstar in WA, Just get them do a check up and some patch up if required.
  11. hypergear
    You can dill at where the two main collectors meets then mill the divider 20mms in and weld a screamer from there. I saw couple done and worked that way and getting better result then externally gating from the turbine housing.
  12. hypergear
    You can run an 50mm external gate from the factory exhaust manifold, which results the most significant gain without having to go through the hassle of changing the whole exhaust setup.

    E70 was like $1.02 when I filled last Thursday.

    Well, there are no differences in fuel between the two runs, They all been drained out through the fuel pump, and the pump had a rubber pickup that sit on the bottom of the tank. So the fuel are identical. The 98 was carried in 20L drums and removed on the end of the run using same method. The tank is then filled up with E85 again.
  16. hypergear
    Well my car's on E85 full time now. It keeps every thing clean including engine oil, and E85 servo is just 500 meters off road from where I am. My current pump is wabro with a rubber fuel pickup hanging off the bottom, there could be a 1L of E85 diluted into 20L of 98. E85 generally makes a average 40kws more then 98 then lets say it maxes at 300rwkws on pure 98 on my setup, generally means maximum of 280rwkw when fitted on stock manifold internally gated. Either way I'm pretty happy with the final result as it had the most area under the curve for the power level it archived, with brilliant road drivability.
  17. hypergear
    The pump is actually in a small corn on the base of the pump right?
  18. hypergear
    The e85 has been drained by the fuel pump. And filled up with 20l of 98. Difference was about 10 degrees of timing. The 98 runs appears to be slightly more responsive.

    I was running .80 gap pretty much all the time. Probably need to check and make sure it is the right plug. I accidentally used some CA plugs in there and it was miss-firing up top.

    TR43 made in 2007. Brings back lots of memories, but old now.

    It can be done, gain is more significant if the external gate is fitted on to the exhaust manifold. Obviously Externally gated setup would pickup more power. There should be 20kws gain running external gate on my current setup.
  22. hypergear
    The 5 bolt externally gated version is cheaper then the bolton internally gated version. That is $1100 The factory bolton version is $1375 and oil line is additional $88 which is required to complete the setup. For any one whom's looking for the externally gated setup, I can supply brae auto's high mount manifold with any turbochargers, with $200 discount off total.

    93 model R33 GTST Forgied CP pistons, valve springs and stock every thing else. 800cc injectors 600x300x75mm Front mounted cooler Xforce 3inch turbo back exhaust Profect B electric boost controller Brea bolton manifold. SS2 prototype (290612) Internally gated. 14psi actuator, internally gated. 4inch intake pipe Adaptronic Plugin Greedy EBC Max of 312rwkws on BP 98 and 210rwkws by 4000RPMs 22psi by 3750RPMs, 20psi by 3650 RPMs: Max of 348rwkws on E85, probably another 15kws in it as my fuel pump is out.

    Further updates. This is the 2nd SS2 prototype been trailed. More responsive and made more power to previous version. Internally gated. Max of 312rwkws on BP 98 and 210rwkws by 4000RPMs 22psi by 3750RPMs, 20psi by 3650 RPMs: U Max of 348rwkws on E85, probably another 15kws in it as my fuel pump is out. I believe this turbo would make a pretty responsive 250~280rwkws internally gated on a stock manifold on pump with around 18psi of boost. Would go crazy to run on external gate and e85.
  25. hypergear
    You will find most int gated turbo do that. ext gate will help.
