    Yes and I think I can make it street drive able too.

    The turbocharger is complete. I'm waiting for Trent to come back from the UK to tune it. I've also made an even more advanced VNT system, it should be able to knock lag out even further, Looking to trail it on the SS4CBB turbocharger. Hopping to archive 20psi before 4000RPMs and 450rwkws+.

    Did you get the braided oil line with the turbocharger from whom ever you got it from? many of them were high flowed using a bush bearing setup which do require lot more oil to run compare to factory turbochargers. There is a oil restrictor in the factory oil hose as well as the benjo bolt. You can not use a bush bearing highflow Unless they have been replaced.

    Thanks for the input Disco, that would share us with more light into the turbo systems of the EVO series. When making a customized compressor wheel, the size of the actual wheel no longer represent the approximate power output, how ever depending on blade and hub profiles, plus individual preferences. In comparison. I'm pretty certain that the the standard 74mm SS2BB with .82 turbine is a very close match in terms of power and response to the HTA3076. And VNT result of that is in page 395. SS3 is closer to a 3582 equivalent, and pretty laggy in standard .82 turbine housing. I've only built 3 of those in the past and one of them was a high flow that made 344rwkws on E85 Auto, internally gated, stock manifold as a factory replacement.

    I've had few CHRA options to high flow the 300zx turbos, how ever the smaller ones didn't shown an great difference in terms of response, while the largest combination I've used (ATR28G1) made the most power. So I stick only to this profile now. Bennys high flows where using the ATR28G1 CHRAs, Which are 2860rs equivalent. We can run FNT nozzle in those housings and bring up the down low response, while Billet SS1 and 1.5 are also now options to consider, since none of them where invented during my time with the 300zx. Best is highflowing them with a pair of stock manual turbos that has .63 T2x rear housings. Also VNT option is now available. I've only released it with SS chras, and for standard Engine under comparison it worked best with the SS2 CHRA. Price starting from $2000 with optional roller bearing centers for now. I Will be into VNT Type B developments for the next few weeks. It will be an expansive and time consuming project to build, how ever for some thing makes 20psi by 3500RPM and 400rwkws+ is welly worth the efforts.

    For the 300zx turbocharger high flows, I've seen 320rwkws on pump 98 so far. that is from Benny's blue Z on the 300ZX forums. those are capable of doing around the 360rwkws mark with supporting mods.

    The two T67s had very similar response while our billet version made 40kws more then the Kando item. We can certainly do the upgrade if you have a Kando T67 item. Either way, I think the SL2 + 25G type of turbochargers might be good for certain tracks or drags that response don't bother too much. The standard SS2 which made 20kws more then the Kando T67 and 15kws lesser then our SL25.5, is a much of a better and smoother turbo to use on road. While the VNT version of that is even more responsive then a 21U high flow while maxing out at 385rwkws. It is probably the best road turbo there is.

    I don't really know much about other wheels. The SS wheels has been developed through time from data collected from many dyno runs. Like a mm difference in the trim of hub, tip height, wheel crop or degree in the blade angle, they all contributes to a small change in the dyno reading (that's also why a hub dyno is an accurate tool, it can map the tinniest changes made from a small alteration) , and from there I could work out the best combination of a good performance wheel for a Rb25det. Once a base wheel is worked out its just a matter of extending/retracting wheel length using trail data to work out the size required for a particular power level.

    There won't be any carbon build up there. Original VNT won't work in a high performance application, It is not a traditional VNT system, but based on its principle and has the same effects. I'm not worried about the reliability of this housing at all. But more interested in how to have them produced with better affordability. The aim to to retail them at around $1500. Its interesting of how much water content E85 has. My exhaust manifold and turbine housing is always filled up with water when I remove them.

    Been driving the VNT SS3 every day for almost weeks now. Unlike other turbos at certain rev ranges stepping the paddle on the floor result in a blank spot. The SS3 VNT has no blank spots, G force comes in straight way with a touch of acceleration. It doesn't have a "hard forced in seat pull" feel after 4500rpms like most turbos do in this range, it has a very smooth acceleration sensation, that pulls harder and harder from the start revving towards limiter. Also because the smoothness in acceleration there isn't a sudden peak of torque, which helped those tyres to grip a lot better. It makes a very fast car and should definitely pull some serious lap times on tracks. Might get Sxxricho into sponsor ship with this turbocharger, Pretty sure he will break his previous records with it.

    I'm building one now for the R33. Probably be ready by the end of next week then just have to wait for Trent to come back from UK again for tuning. But if that works out well then the same concept can be used in all T2x turbine housings.
  12. hypergear
    PU.82 is possible. The current turbine housing is based on the external gate version of that.
  13. hypergear
    No Need for oil restrictors. They already got a .5mm oil restrictor built into the thrust pin.

    NSW wake field Time attack 4th fastest lap from John Sxxracer (?) with stock Rb25det with a 21u High flow making 265rwkws.
  15. hypergear
    There are bit more in it. When it maxes out the upper rev power and torque merges together per additional psi of boost. This one is still increasing both power and torque evenly per additional boost added. We didn't bother squeezing maximum power out of it as the project goal was 400rwkws and this car needs cams.

    Some of yous have already seen my result. It is still reasonable to keep this thread updated with latest reslults obtained from a Rb25det. Plus I think this is also the most responsive 407rwkws any 2.5L Rb25det ever got on stock cams and factory cam gears. Details: 93 model R33 GTST Forged CP pistons, valve springs and stock every thing else. 800cc injectors 600x300x75mm Front mounted cool Brae high mount exhaust manifold HPVA 50mm external gate plumbed back. Xforce 3inch Cat back exhaust 100 Cell Cat Profect B electric boost controller 4inch intake pipe Adaptronic Plugin Power so far is 407rwkws @ 24psi E85 Fuel HyperGear ATR43SS3 CBB VNT Turbocharger. Turbocharger reached peek power of 407rwkws on 24psi of boost This turbocharger had big turbo's top end while retains small turbocharger's down low. I've overlaid my result against result from a high flowed stock R33 21U turbocharger.

    Thanks for the feed backs. I will be back with the SS1PU with VNT turbine next week, if test of it goes well with the Rb25det then I will leave this turbo with Trent for his Cefferio for some track work and in comparison to his current TD05h. With the GTR I can modify the original -5 turbine housing you have with the VNT setups, the only problems is fitting 2nd actuator and bracket, which you might need to make some alterations under the engine bay to make extra room for. But apart from that it shouldn't be a issue.
  18. hypergear
    Thanks for the feedbacks. I can make it work with the GTR turbochargers, you will need to find room under the bonnet as they will need to run two actuators side by side. I don't think there should be a reliability concern, concept is pretty solid and working well. I can make it working with your PU high flow as well, once again just need to find room to fit the additional actuator unless going high mount. It should knock lag off by about 500rpms.
  19. hypergear
    Check Page 365 for actuator preloading instruction. Note it is a analog valve so it doesn't require a lot of boost to initiate the opening process, Preload keeps it shuts for longer, resulting in better response. Some one drop off a dead Evo 10 turbo last week for high flowing. That is pretty interesting working with inverted wheels (why would they do that). Its going to be a inverted SLSS2 will upload photos after its completion.
  20. hypergear
    Well, with the current turbine housing on it won't make any differences compare to before the turbine wheel was grinded. We can supply a .63 or .82 turbine housing that is machined to suit your wheel. With a customized wheel it is hard to approximate the output.
  21. hypergear
    By trimming down the inducer height can result in increasing of response as gas velocity is higher when they squeezing though smaller gap. Been used on a smaller engine previous perhaps assume it had the right turbine housing, or it might be be people experiencing concepts. To make this work the turbine housing needs to be sleeved up to the height of the wheel tip then machined to suit the wheel profile. Can be done.

    That is the wastegate lever extender piece. They all been tiged by a well know member here, I haven't seen any with this issues but I guess shit happens and I will rise the concern. It won't damage the turbocharger or the engine, If you like to send me the adaptor piece I will have it repaired for you under warranty. If you decide to have it welded your self, make sure preload the actuator rod after welding. That will makes a big difference in response.
  23. hypergear
    I can ask him next week. Going back to tune my Kia . As far as the result concern, it doesn't seems like this turbocharger is maxed out. As shown with increase of boost result in evenly increasing of power and torque. When the turbocharger is getting maxed, the upper rev power and torque usually merge with an additional psi of boost. I guess it was late and we all got excited that it made 400rwkws+ and left for hamburgers.
  24. hypergear
    Thanks for your support. This particular one will cost $2500 to produce, the ceramic rollers alone is $400. Plus all other little engineering work, the making of it is very involving. I can also build you a ATR43SS4 in VNT turbine setup for the same price. Which is I believe para with GTX3582 in terms of HP, without the lag.
  25. hypergear
    The VNT system made a large turbocharger drive like a baby turbo while still been able to pull the numbers up top. I've overlaid today's result against a high flowed R33 turbocharger's result:
